The Aero Precision M4E1 Complete Upper 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. An 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. The M4E1 Complete Upper 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. The Aero Precision Threaded Takedown Pin Detent Recess allows users 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). An Increased Magwell Flare means an increase in 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.
