Re: The good AR10 builders?
Noveske is outstanding. I have a AR-10 Noveske in .308win with a 21" barrel. The lower is Armalite, handrail is Noveske and I understand he uses PacNor SS Super Match barrels. I'm very happy with the service, build quality, and accuracy. John N. did some repair work on it for a cycling problem and the cutomer service he provided was very good. Rifle shoots blistering groups with 175gr BH and HSM ammo.
I think he is hard to get hold of these days, and I'm not even sure they are taking new build orders right now.
