I'm interested in trading two AR uppers (a full-featured A2 Gov't profile and a stripped A2 heavy-barrel) for a 1/7 Chrome-lined 14.5" M4-profile flat-top upper receiver with carry handle and a permanently affixed Phantom Flash Suppressor and, either a CAVARMS collapsable stock assembly or a Colt M4 collapsable stock assembly. Basically, I wanna turn my 20" into an M4gery.
Here's a photo of the uppers I have to trade; I haven't got a bolt-assembly for the HBAR and have never shot it. The para-cord comes off the Gov't profile upper quite easily. They're both Colt 1/7 Chrome lined barrels on Colt uppers.
I'll toss-in the A2 buttstock on a whim if I can pick up a collapsable one easy enough.
