Aero Precision M4E1 Stripped Lower and Assembled Upper Combo Set (BLEM) -FDE
M4E1 Lower Receiver in FDE
M4E1 Threaded Assembled Upper Receiver in FDE
M4E1 Lower Receiver Features:
- 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).
- 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.
