When I benched my 18" SS I was able to get 1/2" to 3/4" groups, faily easily with a 10X scope and 69 gr FGMM. I'd say the Noveske SS barrels are 1/2" to 1" guns. Many people claim the short barrels(i.e. 10.5" to 14.5") are sub-moa barrels. I've never really benched my short barrels, but I'm getting 1", to 2" groups at 100 yds with a Crusader barrel with my Aimpoint T1, which is a 4 MOA dot. I know it would tighten up if I put a scope on it. With a Noveske, the barrel is really what its all about, although Noveske only uses the highest quality Mil-Spec parts, put together properly. Fit and finish is great. I've owned all types of AR'S (Noveske, LMT, Armalite) and been issued, Diemaco's and Colt Canada C8's, and I like my Noveske's best (Disclamer: Never owned/handled/fired a KAC). Noveske is also a small company, run by John Noveske. He is a fanatical about his guns and I love his personal philosophies.
