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.
Inside our upper features M4 feed ramps to aid in chambering during high rates of fire. And outside the T-marks in the Picatinny rail’s slots are painted to aid in fast exchanges of optics.
Please note: this is a truly stripped upper receiver, with NO forward assist or ejection port cover installed, so you can truly customize every aspect of your rifle. The Brownells M4 Stripped Upper Receiver is a top-tier upper receiver, at a great price.
