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 Type III Hardcoat anodized. Spike's cut the M4 feed ramps before the anodizing process to avoid reliability issues down the road. The side walls of the receiver are flared to eliminate accidental bolt release problems and the upper receiver is also machined in a way that lets you use the popular Magpul BAD lever.

NOTE: Not all aftermarket bolt catches are compatible.
