Shop with KYGUNCO for the best selection, competitive pricing, and exceptional customer service. Experience the difference that comes with buying from a trusted outdoor retailer with over 20 years of experience in the industry. - Threaded Bolt Catch Roll Pin - Allows for simple installation of the bolt catch and virtually eliminates the chance to damage the finish during installation (pin included). 1/16" Hex Key required for assembly. - Integrated Trigger Guard - Eliminates the possibility of breaking the trigger guard tabs by integrating the trigger guard into the lower, creating a stronger more rigid platform to build upon. - Upper Tension Screw - Allows users to fine tune the fit of the upper and lower receiver using a nylon tipped tensioning set screw inserted in the grip tang of the lower receiver. This provides a tight fit with any standard AR15 upper receiver. - Threaded Takedown Pin Detent Recess - Allows user to easily install the Takedown Pin detent and spring with the use of a 4-40 set screw (no more launching detents across the room). - Increased Magwell Flare - Increased the flare of the magwell to aid in quick and efficient magazine changes. - Marked and milled to accept short-throw safety selectors, but will work with standard selectors as well. INCLUDES: - Stripped M4E1 Lower Receiver - Nylon tipped tensioning set screw - Threaded Bolt Catch Pin ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
