Help me ID this upper!

No, it doesn’t matter. It’s more of me being curious.

It’s an old beater that I paid very little for. It works fine as is...but I have a bunch of extra parts that include a barrel and a BCH...I figure I’ll build something just to pass the time.

I think I shall call it boredom.

K, pretty sure i know which upper... Is there a prize? Lol

I do believe you are correct.

Prize? Hmmm

Do you need any small AR parts (springs, detects, etc)? If so PM me what you need and if I have it to spare...it is yours. I’ll even cover shipping!

**edit to add: I also have some 1911 parts

I was just kidding. Thanks but I will pass.

Oh that's a 'Ghost Gun' upper... I'd know it anywhere.
