Aero Precision M4E1 Stripped Lower Receiver

The Aero Precision M4E1 Stripped 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, they have added a threaded bolt catch pin, and a milled in, oversized trigger guard. The lower also features a flared magwell for reloading.
