Hard Hitting and Rugged, at home on the range or in the field, serious carbine shooters deem the Armalite® AR-10A4TM Carbine as the heavy caliber to own. Tactical flexibility combined with the compact length of the 16" barrel and full length stock are standard to any A4 post-ban carbine model; but add in the advancements that our engineers have made standard on every Armalite AR-10, such as improved feeding, extraction and ejection, and there is not another heavy caliber carbine that can compare.
The AR-10A4 Carbine offers the same sighting choices as the AR-10A4 SPR in a handy compact format. Hard hitting and rugged, at home, on the range or in the field. All our AR-10A4 and AR-10(T)TM rifles feature our clamping gas block, allowing the removable front sight to be rotated to zero. This assures that the rear sight is centered and full left and right windage movement is available when shooting in strong winds.
