Retroarms New Gen CNC Body for M4, 7075 Aluminum, Black

The Retroarms New Gen CNC body for M4/AR15 is milled from a solid block of aircraft-grade EN AW 7075 T651 aluminum (duralumin), a material stronger than ordinary structural steel. Inspired by the receivers of real firearms, it offers far greater durability than zinc-aluminum alloy cast bodies, at a low weight.
