Re: WOA 26" Match Upper or RRA 24" Bull Barrel Upper
I shoot a WOA on my Colt lower, a 1:7 twist with the double pinned sights. Its a 600 yd MR gun I wouldn't consider anything else. John can fix you up if you can handle the wait. I have a a 1:8 RRA NM and its not quite as predictable but I have no real problems with it other than the sights don't measure up to the WOA.
don't ever be fooled into believing security is a good alternative for freedom.
