Brownells Brownells Brownells 75th Anniversary - A Shooting Heritage

Precision Forged From High-Strength 7075 Alloy For High Quality Custom Builds

M4/A3-style upper receiver is available stripped or with the forward assist and ejection port cover already installed. Precision machined from a 7075 T6 aluminum alloy forging to USGI dimensions, and ready to mate with the mil-spec lower and internal components of your choice. Includes M4-type feed cuts and alphanumeric position markers stamped into the rail slots. Hardcoat anodized to resist wear, add strength, and protect from corrosion. Hard dry-lube surface treatment protects the anodizing from scuffs and reduces friction between bolt carrier and receiver walls for ultra-smooth operation, less wear, and longer service life.
