Complete Diemaco upper for sale. 16" barrel C MP marked, government profile. Have the original semi BCG and a second full auto carrier. Came off a trade in rifle with a Rock River lower, the upper was a recent replacement and is in really good condition. The lower has definitely seen some use. I'm asking 500 for the upper. The KAC 300m rear sight is another 150, the aim point PRO is 350, lower is not available. If you want it all, I'll take 900.
