Armalite AR-10A4 Carbine Complete Specs and Full Gun Specifications

The AR-10A4 Carbine offers the same sighting choices as the AR-10A4 SPR™ in this handy compact format. Hard hitting and rugged, at home, on the range or in the field. All our AR-10A4 and AR-10(T) 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.
