Receiver

The Spike's Tactical PHU Skull stripped lower receiver is precision forged from 7075-T6 aluminum and finished in a black MIL-A-8625F Type III Class 2 hardcoat anodize, the same finish specification used across mil-spec AR-15 platform components. The low shelf trigger pocket supports standard Mil-Spec AR-15 fire control group components and carries RDIAS compatibility. The receiver is compatible with standard AR-15 pivot and takedown pins, standard AR-15 safety selectors, standard AR-15 pistol grips, standard STANAG magazines, and Mil-Spec AR-15 receiver extensions, making it a straightforward Mil-Spec compatible foundation across the multi-caliber AR-15 build spectrum. The Pipe Hitters Union skull logo is roll marked on the receiver alongside the Spike's Tactical roll mark, giving the lower a distinctive exterior marking that stands apart from standard roll mark patterns.
