Re: AR 15 Guys ??
the faster the twist rate, the better it will stabilize heavier bullets. I think there's a 77 grain match bullet out there that is better suited to the 1/7 twist. 1/9 is universally the best choice for most shooters but you won't be disappointed by a 1/7, unless you are shooting really light bullets. Colt, Smith and Wesson, Stag, Daniel Defense, Rock River Arms, CMMG, there are so many good ones out there, I don't think you can go too wrong with any of them. I'm not a fan of Olympic arms, however...
I have a Colt for work and a personally owned Bushmaster. both shoot fine, the colt is a 1/7 twist, but I don't shoot match bullets so it doesn't really matter to me.
