I posted this in the AR Discussion section earlier today. So this is a double post.
Thought someone might know?


I bought a RRA Upper last week from PK Firearms. I got it today!! Do manufactures usually but there name on the upper. I don't see a RRA Stamp on the flat top? I'm new so sorry if this is a dumb question. How would anyone know who manufactured it if it's not labeled or marked?
Thanks

I bought a RRA HBAR upper from PK last month.

It has no stampings of any sort on the barrel.

The finish is the most beautiful shade of solid black I've ever seen.

Did you get the 16 S.S Barrel?

No, it is a 20in HBAR flat top.  I was suprised also not to find any stampings on the barrel.

I had a RRA 9mm upper, but can't remember if it had any markings or not on the barrel.

I haven't seen any with marking on the Barrel, Just on the Receiver by the Charging handle. The little RRA Logo. There are no markings anywhere on mine.
