Yep but Smith is the only one that advertises 1MOA barrels out of the ones you listed...and when Smith is not building Mil-Spec rifles that kinda blows all that out of the water. And when you look up the specifications for a mil spec AR they spec at 2 to 2.5MOA barrels. Smith doesnt Smith is building Modern Sporting Rifles to modern material specs, the pieces may be the same size as the pieces the emulate but the materials are better, the tolerances are tighter and they ARE NOT made to 2 to 2.5MOA accuracy. Where as the S&W15PC is guaranteed to be 1MOA, Colts, and Sigs and Armalites are not. I happen to like the term Modern Sporting Rifle...it is there to keep the mil-spec people from getting their panties in a bunch!!!
