M4E1 Low Profile Stripped Lower Receiver - OD Green Anodized (BLEM)

NOTE: This part features a colored anodized finish. These finishes are held to different aesthetic standards than parts finished in black anodizing or Cerakote. For more information on colored anodizing visit our Knowledge Center. Featuring a more subtle Aero 'A' Logo this Lower Receiver compliments your low profile rifle. The 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 features that challenge much more expensive billet options and 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.
