The XCR-L MID has a Mid length monolithic upper which can accept a wide range of calibers and barrel lengths from 12” up to 18.6”. The upper covers a 12” barrel up to
the threads of the muzzle. It uses our Standard (longer) Gas System for supersonic
calibers and our Short Gas System for subsonic calibers. In either case the gas system
is inside the upper receiver and can be adjusted without removing the barrel. The
XCR-L Mid can be used for almost any purpose including competitive shooting, hunting, home defense, military and law enforcement. It is available in Rifle, Pistol, and SBR configurations. See all XCR L models.
