The XT3 is a durable gun with very high-quality components, including a precisely milled action bar with weldless design, a ratcheting barrel lock ring, and a solid, dual-ring gas piston. Fed by a detachable, bottom-feeding magazine, the XT3 also is the fastest-cycling semi auto we've ever seen. This popular tactical version features a removable muzzle brake and 18.5" barrel. Ships in a hard case with sling and two five-shell magazines. A limiting screw may be installed to limit the magazine capacity to two shells.
