If your question was directed to me (The OP) the lower is a Rock River. The barrel is a GI A2 FN 1/7 chrome lined. It was used and gauged at a four on throat erosion. So... well used and well past 1/2 or better of its service life but good enough for the time being and the price. It does group nice enough at 50meters with SS109 junk. The upper receiver is an A2 DPMS like new. The stock is a A2 ??? that looks kinda gray IMO. The bolt and carrier are Young Manufacturing. The lower parts kit is Double Star. Incidentally I was a little concerned with the Double Star as I know nothing about them. But it was all GTG. Even the little things that bug me like the selector not lining up correctly. It does.
Now I need a Dura Coat job. Anyone have suggestions on who and where?
