AR-10® B-Series Carbine


Hard-hitting and rugged at home, on the range or in the field, serious carbine shooters deem the Armalite AR-10A4 carbine as the heavy caliber to own. Tactical flexibility combined with the compact length of the 16-inch barrel and collapsible stock are standard to any A4 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. All of 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 leaving full left and right windage movement available when shooting in strong winds.
