This A2 Colt marked upper" C M " looks to be painted in some durable black spray paint.
It comes stripped.
Just below where the A2 sight is to be placed is bent. Not much, but is still bent.
As usual, I describe these kind of uppers as parts for a toilet dispencer or a fixture for a A2 upper LAMP body.
I have one in my gun room and it is really cool.
However, with a a little work, it could be usefull in an A2 build.
Has 1\4 blemish on the right side.
$15 takes it.
