Brownells BRN-15 M4 Stripped Lower Receiver Black

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 Lower Receiver is that component - the perfect starting point for many an AR-15 build. Starting with a 7075 T6 aluminum forging, our stripped M4 Lower Receiver 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 anodize Mfg: Brownells
