A tactical workhorse, the AR10TAC18 is the perfect tool for duty and defense. All Armalite Tactical Series rifles come equipped with MAGPUL MBUS flip-up sights and MOE+ pistol grips. The dual-purpose flash hiding compensator tames recoil while reducing signature. The sturdy 15″ tactical Key-Mod handguard provides ample hand placement and a full-length MIL-STD 1913 12 o’clock rail for sights an accessories. An adjustable gas block also allows the rifle to be individually tuned for optimal performance for your choice of ammunition and/or suppressor use.
