My bud is a National Match shooter.
He attended Camp Perry regularly in the 80's and 90's and made the President's 100 one year, so he's no slouch.
Recently he had both M1A's rebuilt and after much thought and research, he bought a RRA rifle.
He had some work done to the trigger and sights, and liked it so much he bought a National Match version too.
He says RRA was the only maker to offer a guarantee of accuracy of 1 MOA.
He's getting astounding groups, says his reloads aren't "there" yet, and he's still getting used to a totally different type of rifle.
His 600 yard loads are a 80 grain Match King, and his shorter range is 52 grain Match King bullets.
With a 10X Leupold scope on his first rifle, he's getting 1/2 inch groups at 100 yards which you don't get with the M1A.
If I was looking for a Match AR, I'd be buying a RRA with results like that.
