The Aero Precision M4E1 Lower Receiver delivers billet aesthetics in a forged package. This custom designed enhanced forging is machined from 7075-T6 Aluminum and compatible with all mil-spec AR15 parts. Aside from the visual upgrades this custom engineered design provides that challenge much more expensive billet options, we have added several functional features to the lower receiver to simplify the assembly process for the at home builder.
M4E1 Lower Receiver Improvements:
- 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 Aero Precision M4E1 Lower Receiver
- Nylon tipped tensioning set screw
- Threaded Bolt Catch Pin
Armstopia (store manager) –
VERY easy to build and I definitely recommend it for your first AR build.
Benjamin –
I built my first AR-15 on this platform. I like that the trigger guard is part of the machined block. Theoretically this adds strength to the lower. I’m also a big fan of the moderately flared magwell. The fit and finish are great. I like the coordinating threaded upper and intend to buy another for my next rifle or pistol.
Look forwards to doing business with Armstopia again.
