Quick Takedown Upper Receiver Build Kit, 13" Rail

Allows Barrel & Handguard Removal Without Tools

Specially-designed receiver and handguard incorporate a unique barrel mounting system that allows the user to quickly and easily remove the handguard and the barrel without tools and break down the rifle for easy storage or transport. Barrel and handguard are secured to the receiver with a hand-tightened barrel nut along with a pin and cam lock for a rigid, rock-solid setup. Accepts barrels with rifle-length gas systems and A2-style front sight tower/gas block or shorter barrels with low-profile gas blocks. Extra barrel nuts can be purchased to allow additional barrels to be used with the takedown system for maximum versatility.
