The Nuke is a 9mm-dedicated upper, based of the Colt 9mm 633 "breifcase gun" that was purchased to defend nuclear power plants within the continental United States. 


Differing from a regular slicksided upper the Nuke has no cam groove, nor does it have a gas tube hole. 

This is to prevent gas from venting out of the receiver and into the handguard area, which is espcially usefull when running suppressed. 


For pistol calibers only- will not accept any rifle caliber or direct impingement parts. 


Machined from billet and available in Black Type III hard coat or bare bead blasted.

Does not have feed ramps
