The Spike’s Tactical billet upper Gen II receiver is not just another different cosmetic alternative to forged upper receivers but it’s actually designed with functional upgrades that aren’t available on other billet upper receivers! It is machined out of 7075 billet aluminum and finished off in a durable Type III Hardcoat anodized. 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 don’t let you do.

NOTE: Our billet upper is not compatible with all aftermarket bolt catches.
