Sometimes you want the latest, updated, tweaked component, and sometimes you need a basic stripped receiver where the production effort goes into quality, rather than bells and whistles. The Brownells M4 Stripped Upper Receiver is that component - the perfect starting point for many an AR-15 build.
Starting with a 7075 T6 aluminum forging, our stripped M4 flattop upper is precision machined to final dimensions that make it compatible with the multitude of available "mil-spec" AR-15 components. It has a matte black, Type III hardcoat anodized finish, mirroring the military requirement.
Machined from 7075-T6 aluminum forging
Matte black Type III hardcoat anodized finish
Mil-spec dimensions for maximum parts compatibility
Standard .250" dia. pivot/takedown pin holes
Inside our upper features M4 feed ramps to aid in chambering during high rates of fire.
