Re: Sooo....Who sells a real 1/2" moa AR Upper?
Oly Arms Ultramatch is very accurate, but the minimal SAAMI specs chamber (Clymer reamer)was not suitable for my purposes. I need a chamber that's accurate, but not too tight (from a reliability standpoint in a combat environment), and something that can handle higher 5.56mm load pressures. That's why I went with the Wylde chamber on my SDMR. Also some of the really accurate AR barrels mentioned are bull barrels and that's also unacceptable for me for combat applications, (bench rest ok) --if I have to carry it, I want it to be light. Weight is a whole different subject, but I've seen M4's w/ so much commercially marketed AR junk attached, their almost as heavy as an M2, lol.
..So when the individual does make the decision about 1/2" MOA capable upper, the obvious question they must also ask themselves is "what do you I want to do with this?" and is an important one. If it's benchrest, the 300 lb barrel with the heavy baseball bat scope -- not a problem. Or the 1/2" space gun for competition -- that's is fine. If it's a rugged environment like Afghanistan or Iraq, different considerations and there will be trade off's.
My SDMR set up was my choice for my purposes, and I believe mine is 1/2 MOA (or close to it). Headed back to the range with the Gieselle trigger now installed (and GI trigger out)..will post soon.
