Hard Use Umbrella Corp Receiver. It's how Umbrella Corporation designates a receiver that might not be the prettiest thing to look at, but it gets the job done like a pro. You don't take these home to momma, you spend a few bucks and use them like the HUUCRs that they are. As Umbrella blems, they may very well look better than other manufacturers' standard parts, but even so these uppers may have some dents, dings, and anodizing issues. All of our standard upper receiver specs apply including M4 feedramps, no "T" markings, our deep laser engraved logo on top of the rail, along with a new surface mark to designate these as HUUCR uppers. Even though their standard uppers come fully assembled, these are only available fully stripped....

Barrel assembly should be performed by a qualified Armorer: Mil-Spec AeroShell 33MS barrel nut grease is included.
