Aero Precision, M4e1 Forged Ar-15 Lower Multi-Caliber Flat Dark Earth Cerakote

The Aero Precision M4E1 Forged Stripped AR15 Lower Receiver in Magpul FDE Cerakote brings the M4E1 series� workmanlike improvements to builders who demand a durable, user-friendly foundation for range, duty, or hunting rifles, and because this is a stripped lower it ships to an FFL dealer per federal law. Machined from 7075-T6 forged aluminum and weighing just 8.61 oz, this lower features an integrated trigger guard to eliminate fragile tabs and deliver a stiffer platform for match triggers and two-stage setups, a threaded bolt catch roll pin (included) that prevents finish damage and makes installation straightforward, and a nylon-tipped upper tension screw in the grip tang so you can dial tight receiver fitment with any standard AR15 upper. The rear takedown pin detent recess is threaded for a 4-40 set screw to keep springs and detents from disappearing during assembly, the magwell flare is increased for faster reloads in competition or high-pressure scenarios, and the lower is milled and marked to accept short-throw safety selectors while remaining compatible with standard selectors and AR components. Made in America and finished in Flat Dark Earth Cerakote, the M4E1 lower is an ideal choice for custom builds across multi-caliber AR platforms where durability, repeatable assembly, and refined ergonomics matter.
