The Aero Precision AR-15 barreled upper receiver is built around the M4E1 Threaded upper receiver and is designed for use with standard barrel nut setups. The receiver is forged from 7075-T6 aluminum and precision machined to M4E1 specs to ensure proper fit with Mil-Spec and aftermarket parts. It is matte black hardcoat anodized and features laser engraved T-marks. This 18” .223 Wylde barreled upper comes with the Atlas R-One M-LOK free float handguard with a full length picatinny top rail and an extremely slim 1.3” inner diameter.
Features:
The .223 Wylde 18” barrel is machined from 416R stainless steel with a bead-blasted finish, a rifle-length gas system, and a 1:8 twist rate. It has an M4 feed ramp barrel extension and is magnetic particle inspected and high-pressure tested. A standard A2 flash hider with 1/2x28 threading is attached to the muzzle.
Aero Precision takes some of the most state-of-the-art manufacturing techniques and equipment derived from their work in the aerospace industry and applies it to their products in the firearms industry. They have utilized their knowledge from years of building aircraft components to design and engineer AR-15 handguards, receiver sets, scope mounts, and more. They treat every product as if it were a precision flying machine and adhere to strict quality standards to ensure law enforcement, military, and civilian customers receive a product they can rely on.
