Q: What is the status of my order?
A: The stunningly high level of orders, combined with turbulence in delivery or acceptance of supplies, makes it impossible to provide accurate lead-time forecasts. Remember that a single delay or quality rejection affects literally THOUSANDS of rifles in the production schedule. Under those conditions, we cannot respond to requests for status. We tried, but the level of requests is absolutely higher than the staff can handle even if they did nothing else at all.

Q: What is Armalite’s policy on selling firearms and components to individuals?
A: Armalite only sells firearms and components in accordance with federal, state, and local laws. If you have other questions, please contact us.

Q: I am building a custom Armalite and need some parts. Why aren’t you shipping them?
A: We are now taking orders for even scarce items, but can ship only as supplies allow, and parts are heavily backordered. Some items cannot be shipped because dispatch of those items literally prevents us from shipping a rifle. Rifle shipments must take priority for the moment. We’re pulling supplies in to support the important need for parts and other supplies. Please be patient with us.

Q: I ordered a rifle from my dealer. Do you have the order in your records? When will my rifle ship?
A: All status info from your dealer must come from that dealer. Please remember that many dealers order through distributors, and even if the dealer ordered directly from us, we don’t know which order is dedicated to specific customers. Most importantly, normal business practices dictate that we must communicate through the parties who order from us rather than directly with their customers. Please forgive the inconvenience.

Q: Could you tell me from which date orders are shipping? My order number is **** in case you ship by numerical order.
A: No, as previously noted – we cannot accurate forecast shipping dates. Because one erroneous forecast merely generates many later requests for status, we’ve had to halt status reports until we definitely know when materials will be on hand. At that time, we call each customer due to receive product.

We try to ship in order sequence, and this generally works well with individual orders for parts and accessories.

It does not work well for complete rifles because huge orders placed by many customers block any deliveries to other customers for many months. In this case, we try to allocate some product fairly to everybody. We feel it’s better to get something to many of our friends and customers than to deliver many rifles to the early few who ordered.

We know we won’t satisfy anybody completely, but we can satisfy many customers partially. Please understand that we’re pressing to resolve the situation as quickly as possible. It will seem to you that nothing is being accomplished until you’re notified of your shipment. We apologize to you for any irritation.

Q: Does Armalite accept checks by fax?
A: No. At this time, Armalite does not have the capabilities to accept checks by fax. Please contact us to discuss your options of payment via check.

Q: What payment options does Armalite offer its retail customers?
A: Website customers have the option to pay with Visa, Master Card, Discover Card, and American Express. Retail customers placing orders over the phone have the option of Visa, Master Card, Discover Card, American Express, COD certified funds, personal check, bank checks, or money order. However, Armalite reserves the right to hold shipment until checks clear.

Q: What payment options does Armalite offer its dealers?
A: Please contact us to discuss payment options for dealers.

Q: If I place an order with my credit card and the items are back ordered, will my card be charged?
A: The Armalite website will not allow backorders. If you would like to backorder an item, please call customer service to place your order. In this case, your card will not be charged until the product ships.

Q: How do I become a dealer?
A: If you currently hold a Federal Firearms License, all you need to do is email or fax a signed copy to us. To make it easy for us to contact you, please include your phone number and email address on the FFL. You’ll get dealer pricing for all firearms, parts, and accessories with no minimum to buy, and we won’t bill you till the product ships. If you don’t have an FFL, ask your dealer to become an Armalite dealer in your behalf.


Q: Why do I get an error message when trying to place my web order?
A: The most common cause of errors when placing orders is incorrect payment details or billing address. If your problem persists, please contact customer service.

Q: Can I get my dealer pricing on orders placed on the website?
A: Yes. Please email a signed copy of your FFL and tax information to dealers@armalite.com.

Q: If I place an order over the phone, can I see it on your website?
A: At this time, phone orders cannot be accessed through website. Due to privacy/security and credit card processing regulations, we keep these systems separate.


Q: How do I return a firearm to Armalite to be repaired?
A: If you would like to return an Armalite firearm for repair or have accessories installed, please contact our Repair Department at 623-780-1050 ext 1217 or use the Customer Service section. After talking to the Repair Department you will be given a Return Materials Authorization (RMA) number and instructions on how to ship your product into Armalite. You can email them at psd@armalite.com as well.

Q: How do I return parts or accessories to Armalite?
A: If you would like to return a recently purchased Armalite product, please contact our Customer Service Department at 800.336.0184 or use the Contact Us section. After talking to an Armalite Customer Service Representative you will be given a Credit Return (CR) authorization number and instructions on how to ship your product into Armalite.


Q: Where are the technical notes that used to be located on the website?
A: Over the last few years, Armalite and its parent company, Strategic Armory Corps, have been working diligently to adhere to International Traffic in Arms Regulations (ITAR) set forth by the U.S. Government. These export controls prevent us from making some technical information readily available to the public via web or any other media.

While we understand that this can be an inconvenience to our customers, we believe that these policies are important in preventing our technical knowledge from getting into the hands of foreign governments and groups that wish to cause the United States or its allies harm. We take the safety of our country and troops very seriously, and appreciate your understanding.

If you have any questions regarding these technical notes, please do not hesitate to contact our customer service team so they can assist.

Q: What is a .223 Wylde chamber?
A: .223 Wylde is a specific chamber size originally designed for precision shooting to make the best use of case pressure. 223 Wylde incorporates a longer throat. A longer throat in the chamber allows the shooter to utilize longer length bullets such as the 80 grain HPBT Sierra MatchKing.

What does that mean for 223 Rem and 5.56 Nato (5.56X45)? Your .223 Wylde chambered rifle CAN fire any 223 Rem or 5.56 NATO rounds. The difference between those two rounds is the case pressure, with the 5.56 having the greater of the two. The 223 Wylde chamber was developed to shoot both and achieve optimal accuracy with either.

Q: My rifle doesn’t function properly or isn’t experiencing the accuracy I expect out of it. What should I do?
A: Most technical problems can be resolved by carefully reading the owner’s manual for your firearm. Owner’s manuals for all Armalite firearms can be found in the Library section of our website. If you want a hard copy, just call or email. (See the Contact Us section of our website.) Our manuals are updated as we make design changes or as we receive questions from customers. It’s a good idea to download the most current manuals.

If you still have a problem after reviewing the latest owner’s manual and Technical Notes, thoroughly cleaning the firearm as explained in the manual, and absolutely assuring that your ammunition is not defective, feel free to contact our technical support personnel.

Functional problems must be analyzed as “system” problems. We must consider the firearm, the ammo, the mounting conditions, maintenance schedules, and the shooter.

When you contact us, it’s important for you to have as much specific information about your problem as possible. Information that’s very helpful to us includes:
— Model of the firearm
— Serial number of the firearm
— Sights or scope being used
— Manufacturer and specific type of ammunition being used (including bullet weight)
— How the rifle or pistol was mounted or held (e.g. shoulder fired, bench rested, one-hand firing) and how tightly was it being held
— Approximate number of rounds previously fired from the firearm
— Approximate number of rounds fired since the firearm was cleaned and method of cleaning previously used
— The specific nature of the malfunction or problem encountered.

In order to provide meaningful support to you, we’ll need you to be as specific as possible about the problem. (There’s simply no way to analyze “My rifle doesn’t work.”) Let us help you diagnose your problem.

There are eight steps in the cycle of functioning of any firearm. They are:

  1. Firing – Pulling the trigger to release the hammer or striker to fire the cartridge, 2. Unlocking – Turning the bolt to release it from the barrel, or (in a pistol, tipping of the barrel to release it from the slide,
  2. Extracting – Pulling the fired case out of the chamber,
  3. Ejecting – Throwing the empty case clear of the firearm,
  4. Cocking – Resetting the hammer or striker so that it is ready to be released to fire the next cartridge,
  5. Feeding – Pushing the next cartridge out of the feed lips of the magazine.
  6. Chambering – Pushing the cartridge up the feed ramp and into the chamber,
  7. Locking – Rotating the bolt or (in a pistol) lifting the barrel so that it is held in place to support the cartridge for the next shot.

Try to determine which step in the cycle of functioning is not being performed successfully and provide that information to us.

In addition to cycling problems, it is possible to have a problem with the firearm’s controls including the safety and the bolt (or slide) stop. If you have a problem with any of the firearm’s controls, describe the problem as specifically as possible.

Q: I want to replace the stock of my Armalite and want to know if it is built with a MIL-SPEC or commercial tube design.
A: Armalite currently uses Mil-Spec diameter receiver extensions (buffer tubes). But, previously we used commercial diameter tubes. We can’t tell what you have without knowing the tube diameter. If you tube has a diameter of approximately 1.145 – 1.147 inches, it is Mil-Spec diameter. Anything else is commercial. Note that there is a tolerance in both Mil-Spec and commercial tubes and stocks. The stock will tend to have a little play in it.

Q: Can a DPMS/POF/KAC/RRA/other brand’s upper be put on an Armalite lower receiver?
A: You can install Colt or high quality components made to military standards to Armalite M15 lower receivers, but Armalite doesn’t recommend it. We recommend that you use Armalite upper receivers for optimal fit, matching to the deep black color of your Armalite receiver, and the basic knowledge that your rifle isn’t totally mixed up.

No other brand of upper receiver fits the Armalite AR-10 family of rifles.

Q: What are the difference between the Armalite tactical and match triggers?
A: The mechanisms are based on the same basic design. The difference is the location and shape of the trigger bow, different weights of pull, and tuning the second stage hook in a manner similar to the M14.

The NM trigger bow is mounted farther forward for better trigger finger placement, while the Tactical Two-Stage trigger has the same bow as the usual single stage trigger of the M-16. The trigger weight of the installed NM trigger is approximately 2 pounds lighter than the Tactical Two-Stage trigger, and the NM trigger is tuned so that the shooter won’t be distracted by movement in the second stage.

The two triggers serve different purposes, so a single standard isn’t practical. While NM triggers are outstanding for match use and for casual shooting, the officials of many Police or Military organizations require a trigger of higher weight.

Armalite may use un-tuned NM triggers as Tactical Two-Stage triggers in standard rifles when supply conditions require.

See the M-15 and AR-10 manuals for more information on our Match triggers.

Q: What’s the difference between Eagle Arms and Armalite?
A: There are normally very few differences. Armalite rifles are the top of the company’s line. They tend to be more up to date and include higher quality parts such as chrome lined barrels. They are produced from selected forging. However, internally, they use exactly the same parts. Eagle Arms rifles are intended to compete with lower priced brands. They are extremely high quality rifles in their own right. Armalite used to use only “Armalite” lower receivers for actual factory built guns and sold “Eagle Arms” as stripped lower and upper receivers. This was to differentiate between the two different warranties. Armalite has a lifetime warranty and EA has a one year only warranty. Armalite now offers “Armalite” stripped lowers for sale.

Q: What are the differences among types of muzzle devices?
A: A “Muzzle Brake” is a device that reduces recoil by redirecting gases rearward. It does not hide or eliminate flash. Physically, it typically contains slots or holes that angle rearward. It may greatly increase noise and blast rearward toward the shooter.

A “Flash Hider” is a device that hides flash from the rear and sides. Physically, it is typically cone-shaped without any holes or slots on its sides. It does not reduce recoil or suppress flash. It merely hides flash. It may increase recoil somewhat.

A “Flash Suppressor” is a device that reduces flash by dispersing hot gases radially outward from the muzzle. Physically, it usually has holes, slots, or prongs that radiate outward completely around the suppressor, (or at least horizontally and upward from the suppressor).

A “(sound) Suppressor” is a device that reduces sound, flash, and recoil by containing and cooling hot gases in a cylindrical canister.

Q: Do you still offer custom colors/camouflaging?
A: We are not currently offering custom cerakote or camouflaging. Considerations may be made on a case-by-case basis for quantity orders.

Q: What is the thread pitch on all of your muzzle brakes?
A: The thread pitch depends on the model of your rifle:
AR-10 = 5/8 x 24
M-15 = ½ x 28
AR-30 = 5/8 x 18 UNF-3A
AR-50 = 1 x 14

Q: Will a sound suppressor affect the performance of my M-15™ or AR-10®?
A: Yes. A sound suppressor will increase the rate of fire, which may increase the rate of some malfunctions and may increase rate of wear on some parts. That’s why our Super SASS has a gas valve to reduce the amount of gas powering the gun when the suppressor is installed. When we manufacture rifles specifically for use with a suppressor, we reduce the size of the gas port appropriately. Please remember that suppressors are NFA controlled items, so please observe federal, state, and local laws regarding their use.

Q: What does LSA stand for?
A: Lubricant, semi-fluid, automatic firearms. It was specifically designed in the 1960s for use on the M-16 rifle.

Q: Does Cryogenic Treatment (Cryo) of barrels help in any way?
A: We have not seen any evidence that it helps. Armalite has frequently been offered cryogenic barrel treatment services, with promised increases in accuracy, life expectancy, and easier cleaning. In each case, we have stated that we would consider the treatment only when provided solid engineering data proving the promised benefits.

In late 1998, an experienced High Power competitor and official of Sierra Bullets, Mr. Kevin Thomas, published an excellent article in Precision Shooter magazine that reported results of a well designed test that confirmed no measurable benefit from the treatment.

Until independent, scientific evidence to the opposite is provided, Armalite will not resort to, or recommend cryogenic treatment.

Q: Why does Armalite offer three types of barrels (chrome moly, chrome lined, and stainless steel)?
A: Each barrel has advantages suited to different uses.

Armalite’s chrome moly barrels have excellent internal surface finishes, and offer excellent accuracy for a reasonable price. Chrome lined barrels offer excellent corrosion protection and longer life expectancy, but are more expensive than unchromed barrels. In addition, the process of electro polishing the barrels, and the chroming process itself, tends to reduce accuracy somewhat. Stainless is easy to process to fine surface finishes, and provides moderate corrosion resistance.

Thus, chrome moly is used for Eagle Arms standard rifles, for good accuracy at a low price. Armalite A2 and A4 rifles, in both .223 / 5.56 and .308 / 7.62 normally are produced with chrome lined barrels for hard service use or use under adverse conditions, with stainless steel as an option. All Armalite match grade rifles, the Ts and National Match rifles, are made with stainless steel barrels for superior accuracy and good corrosion resistance.

Q: How accurate are Armalite’s rifles?
A: That depends on which model you have. Armalite manufactures a wide range of rifles with barrels of different materials and different lengths. Generally, the stainless steel and unchromed barrels are more accurate that chrome lined barrels, but the chrome lined withstand moisture and wear better.

In general, when shooting match ammo from a bench or machine rest in calm conditions, our rifles will shoot the following sizes of 5-shot groups:

–Match grade rifles are guaranteed to have accuracy better than 1 minute of angle.
–Carbines with 16 inch long stainless barrels will shoot better than 1.5 minutes of angle.
–Chromed standard grade barrels will shoot within 2 minutes of angle.

A minute of angle (MOA) is approximately 1 inch per 100 yards of range.

Q: What is “Match” ammunition and how does it differ from “Ball” ammunition?
A: The term “match” is much abused in the world of ammunition sales. too often, it’s applied to whatever a seller has on hand in order to sell it to innocents.

Properly used, the term is applied to ammunition that is assembled from specially produced or selected components to improve accuracy. Specially designed bullets, such as open-tip, especially uniform primers, specially weighed charges of stable powder, and high-quality very uniform cartridge cases are often used in match ammunition.

“Ball” ammunition is similar, but of standard quality, often using less expensive open-based bullets rather than open-tipped. It is ordinarily used for military or police use, or produced for sale at low prices to hobby shooters.

If you are looking for high-quality “Match” ammunition, we recommend the Match Grade line from Nexus Ammo.

Q: How many shots can be fired from a barrel before it has to be replaced?
A: Barrel life will vary greatly depending on the caliber of the rifle, the particular ammunition being fired, the rate of fire, how well and how often the barrel is cleaned, and how accurate the shooter insists the rifle must be.

Shooting tracer or armor piercing ammunition, or shooting the rifle as fast as the trigger can be pulled can ruin the barrel in just a few hundred rounds. Firing jacked lead-core bullets at reasonable rates with good cleaning often will allow a standard grade .223/5.56 or .308/7,62 barrel to last for up to 10,000 rounds with acceptable for police use. Target shooters fire at very moderate rates, but their higher accuracy requirements may dictate barrel replacement at approximately 7,000 rounds. The most intense 5.56 match loads with heavy bullets, such as those used by the Army Marksmanship Unit, may require barrel replacement as early as 2,500 rounds. More conservative loads may remain accurate for over 5,000 rounds.

Because of the variables that must be considered in approximating barrel lift, the barrel of your rifle is considered a wearable item and will be evaluated for warranty on a case-by-case basis.

Q: Do both 7.62 NATO and 7.62×39 cartridges fire projectiles of the same diameter?
A: No. In spite of their similar designations, they do not fire the same diameter of projectiles, their cartridge cases are entirely different, and they are not interchangeable in any firearm. And firearms that fire them have different bore diameters. (7.62 NATO projectiles are 0.308” in diameter. 7.62 X 39 projectiles are 0.311” in diameter.)


Q: Why does Armalite object to other companies calling their rifles “AR-10”?
A: First, we object because they aren’t AR-10®s. The AR-10 is a special rifle manufactured by Armalite. Second, the model term “AR-10® is a registered Armalite trademark and may be used only on Armalite rifles or rifles made under license.

Armalite spent a lot of money producing the AR-10 when no one else would. We have spent a lot of time building the name and reputation of this rifle and trademark law requires us to prevent others from infringing on the trademark.

In addition, assuring that our model designation is properly used only with our rifle reduces the likelihood of owners of problematic lower-grade semiautomatic 308 rifles from referring to their problems as “AR-10 problems”.

Q: Can other (DPMS) magazines be used in my AR-10B?
A: No. You can only use Armalite proprietary GEN-II mags, or a modified M14 mags (GEN-I), or unmodified M14 mags held in the receiver with the sling.

Q: Can I use M-15 parts in the AR-10?
A: Some, but not all, parts are interchangeable.

Q: Is the chamber on the AR-10 .308 Win or 7.62×51?
A: All of our AR-10s are NATO chambered and will accept both 7.62 and .308 ammo. The AR-10 can shoot 308 or 7.62 NATO. See the AR-10 owner’s manual for more detailed ammo information.

Q: Will an AR-15 pattern (CAR) stock fit an AR-10?
A: Yes (with caveats). You will need to use either the carbine AR-15 carbine lower receiver extension (buffer tube) with an AR-10 spring and a shorter AR-10 buffer (to allow for the longer AR-10 bolt carrier group) or an AR-15 pattern stock and the AR-10 buffer tube (but it will not collapse all the way). The A2 stocks are the same. The AR-10 rifle buffer is a little shorter in the AR-10 rifle.

Q: I’ve built an AR-15 pattern rifle in the past. Can I build an AR-10?
A: Yes. They are basically the same parts except you will need bigger tools (vise blocks). Armalite even offers a kits part #GSK10A4 (minus the lower receiver—-Call for info.) just for this purpose. Note: You can use a regular AR-15 barrel wrench to take off a standard AR-10 barrel nut, but you will need a special AR-10 barrel nut wrench to tighten the large AR-10(T) barrel nuts.

Q: Where can I buy AR-10 lower receivers and parts?
A: You can order parts directly from Armalite or from DSG Arms and 762 SASS (stocking dealers). If you want to order an AR-10 rifle, lower receiver, or parts, your FFL dealer can order one direct from Armalite.

Q: Why is the AR-10 more expensive than other rifles that look similar?
A: Armalite rifles employ more expensive components and offer features those rifles don’t have (chrome lined barrels, lifetime warranty, better triggers, forged receivers, and Minute of Angle guarantees). These extras cost money.

Q: Can I use an AR-15 pattern gas tube on the AR-10?
A: No. AR-10 gas tubes are longer than the AR-15 tubes.

Q: What range should I zero my AR-10?
A: If using standard NATO Ball ammunition, you can zero for any range shown on the elevation knob.

Q: Why is my bolt locked in the bolt carrier?
A: This problem (normally found with very early rifles) and its resolution are explained fully in the owner’s manual. The bolt has been inserted too far into the carrier before inserting the cam pin and the gas ring has expanded behind a small ledge in the carrier.

When inserting the bolt into the carrier, the holes for the cam pin should align. Never insert the bolt past the cam pin hole.

Q: Why won’t my port door stay shut?
A: It’s possible that the port door detent needs to be freed up. Tap gently on the door with a rubber or plastic hammer. If that doesn’t solve the problem, contact our service department. You may need to send in the upper half of your rifle.

Q: Can you install an AR-30 muzzle brake on an AR-10?
A: No. The muzzle threads are different on the AR-30 than on the AR-10.

Q: What ammo do you recommend in my rifle?
A: Armalite recommends Match Grade ammunition from Nexus Ammo.

Q: Will the M-15 front sight tool fit the AR-10?
A: Yes

Q: What are the torques on an AR-10 barrel nut and the gas keys?
A: Torque for the M15 should be 35 – 80 FOOT lbs. and for the AR-10 45 – 90 FOOT lbs. The torque for the gas keys for both the M-15 and AR-10 should be approximately 55 INCH lbs.


Q: If your M-15’s are MIL-SPEC, why don’t other manufacturer’s parts fit in my Armalite rifle?
A: Because their parts aren’t Mil-Spec.

Q: What brand of ammunition do you recommend?
A: Armalite recommends Match Grade ammunition from Nexus Ammo.

Q: Why does the firing pin leave marks on primers of chambered, but unfired, cartridges?
A: This is normal in all manufacturers’ AR-15 style rifles as well as other designs such as the famed M-1 and M-14 rifles. The M15 firing pin does not have a spring that holds it rearward. Thus, as the cartridge is chambered and the bolt carrier stops, the firing pin is free to fly forward, slightly indenting the primer. However, the firing pin, by itself does not have enough energy to fire the cartridge.

The heavier AR-10 firing pin DOES have a spring installed to assure that its heavier weight won’t initiate a “slamfire.”

Q: How do you remove A2 handguards and install 1913 handguards?
A: Simply pull back on the slip ring, remove the old handguards and replace with the new ones. Sometimes the 1913 handguards are a tight fit, so you may have to slide the front sight forward for more room to work. See your owner’s manual for more information.

Q: Why is there a stamped eagle on the front of the magazine well?
A: It is a factory inspection stamp similar to, and sometimes confused with, the government acceptance stamp. It doesn’t include the additional characters of the government stamp.

It was initially used to mark Eagle Arms rifles that were built in the factory, to differentiate them from rifles built from Eagle Arms receivers.

Q: The front sight base of my rifle has two screws running through it below the barrel. What are they for?
A: They are used on National Match, and occasionally on other rifles, to allow the owner to zero the front sight. Normal manufacturing tolerances may result in the rear sight being somewhat off center when the rifle is zeroed. Armalite’s exclusive clamp style front sight base allows the owner to zero the front sight for windage, and thus to center the rear sight. The military refers to this step as zeroing the rifle’s “mechanical zero.”

To do so, put the rear sight in the center of the rear sight base. Fire a three-shot group. To adjust the next shot group to the left, shift the front sight to the right (and visa versa). Tighten the clamping screws and finish zeroing in the normal manner using the windage knob of the rear sight. Elevation is adjusted normally.

The clamping screws also allow the sight base to closely seal the gases that pass through the base to the gas tube, this improving the power of the operating system.

Q: My receiver has “EA15 J15” marking on it. Could you give me background information on it?
A: Receivers with that marking are manufactured by Essential Arms out of Krots Springs, Louisiana. They have no affiliation with Eagle Arms nor Armalite.


Q: Why won’t my bolt fit in my AR-30?
A: You may have installed your scope base incorrectly. One of the scope rail screws is shorter than the others. The short screw should be installed in the front hole. This is explained thoroughly in your owner’s manual.

Q: Can I adjust the trigger pull in my AR-30?
A: The AR-30 trigger is not user adjustable or user removable. Only the factory can adjust the trigger and assure its safety. User adjustment voids your warranty. Contact us if you would like any trigger adjustments.


Q: Why can’t I sight in my Ar-50 when I have both the 15 and 50 minute rails?
A: There are some variables that are out of our control that can contribute to the problem. Perhaps the scope is defective. Scopes are delicate instruments and can fail internally with no outward appearance of the problem. Also, some scopes have far less range of windage and elevation adjustment than others. If you’re just having trouble “getting on the paper”, start your zeroing at short range with a large target paper. We suggest starting at 50 yards with at least a 12” X 12” target.

Q: Why does my AR-50 leave longitudinal markings on the fired cartridge case?
A: It is normal for small hair like markings to be left on the case due to the pressure of the ejector spring causing the case to hit the locking lugs during extraction. These marks are only cosmetic. They do not reduce the strength of the case.

Q: What types of .50cal ammo can I shoot in my AR-50?
A: Although the AR-50 will satisfactorily fire tracer and armor piercing ammo, such ammo can significantly reduce barrel life. Saboted ammo is not recommended because the sabot can hit the rifle’s muzzle brake, potentially damaging the rifle. See your owner’s manual for more information. Because of the large amount of powder and pressures generated by .50cal ammunition, Armalite recommends factory match grade ammunition loaded by reputable manufacturers.

Q: Can I adjust the trigger pull in my AR-50?
A: The AR-50 trigger is not user adjustable or user removable. In order to fire the large primer in .50 caliber ammo, the sear surfaces are put under high loadings. Thus, the trigger pull is set at the factory to be within safe operating limits and no further adjustments are to be made. User adjustment of the factory pre-set trigger is both unsafe and voids the warranty on the product.
