Spike's Tactical Gen 2 Billet Upper Receiver, 223 Rem/556NATO, Black Finish, Mil-Spec Barrel Nut SFT50B2
We machine this bad boy out of 7075 billet Aluminum and finish it in a durable Type III Hardcoat Anodized finish. Of course, we cut the M4 feed ramps before the Anodizing process to avoid reliability issues down the road. We also flared the side walls of the receiver to eliminate accidental bolt release problems and we also machined the upper receiver in a way that lets you use the popular Magpul BAD lever or other aftermarket bolt catch levers which most other billet upper receivers donít let you do. Because of our beefier design, it allows for less flex than forged upper receivers.
