Noveske Lower, LMT MRP/CQB Piston 556 Upper PWS Buffer Tube, VLTOR Imod Stock, etc....
I forgot,.... I should thank Ranier for getting me that rail.
I went to them because they are a board sponsor, and they came through on a part that nobody knew you could even order.
So, thanks to Mike over there.
Nice. Now slap some sights on it and go shoot it.
I am waiting for some sites from Troy. It may be a week or two.
I have a bunch of others sitting around that I can use to shoot.
Looks good. How is the gas block on there? I don't see pins or screws on the bottom.
I hope this answers your question:

Cool.
I've got the same upper on an M&P15 lower. Great gun, great customer service on LMT's part.
Keep your eye on any carrier tilt. My LMT had an issue with it it.
