Description
The Aero M4E1 Lower Receiver is a flagship product from Aero Precision.
The M4E1 has several proprietary features, most notably it is a FORGED receiver, making it stronger than similarly styled billet receivers. This custom-designed enhanced forging is machined from 7075-T6 Aluminum and compatible with all mil-spec AR15 parts, with a couple of features that make assembly easier.
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 Skeletonized 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 should be lightly snugged and not over torqued
- 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
