Aero Precision M4E1 Lower Receiver
The latest offering from Aero Precision.
Made from 7075 T6 aluminum that is precision machined to final dimensions for compatibility with all standard "mil-spec" AR-15 parts this receiver has a streamlined profile, without the chunky appearance of many milled lowers.
Includes an integral triggerguard, which creates a more rigid, structurally sound receiver than a standard AR-15 lower, while providing extra clearance when wearing gloves.
Comes with:
An easy-to-install threaded bolt catch roll pin that eliminates the risk of damaging the lower’s finish during installation.
Flared magwell opening facilitates fast, one-shot mag changes.
Threaded takedown pin detent recess for easy buffer removal without chasing down a flyaway detent
And has a polymer-tipped tensioning screw in the grip tang that you can adjust for a tight, rattle-free fit with the upper receiver.
Hardcoat anodized matte black to resist surface wear, it accepts standard mil-spec AR-15 fire control components, grips, buffer tubes & stocks
