I'm currently in the process of scoping out parts for an A2 build and to my surprise (not really), finding certain parts is not as easy as your typical run of the mill AR15 parts these days. The first AR style rifle I ever handled was a beat up A2 back in 2006 when I went through USAF basic. Scored marksman at 47/50, and immediately fell in love with the rifle. I want to build one as a nostalgia piece that I can have fun shooting. I did buy the Aero A4 upper and lower a couple years ago when they came out, but it wasn't the same since it had the removable carry handle. I want the real deal A2.
With that said, I'm seeing that A2 stripped uppers are not as common to find. Just for parts reference, I'll be using a PSA Stealth lower receiver and I've noticed that PSA's anodizing isn't as dark as your typical BCM/Aero/Colt finishes. I keep seeing these "teflon" coated A2 uppers and they look about as dark as Mega receivers are. I just want the same anodizing as the PSA lowers, really.
Any suggestions on which uppers to look for? Not looking to spend an arm and a leg on one and prefer to have the rear sight assembly already installed but not a necessity, I can learn how to do it.
