try getting off the bench and see which one you shoot better. try to put 5 rounds in the black from 50 yards in 5 seconds and then post the pics.
neither were designed to be shot from benches at 100 yards.
Mine will.
Every AR I own will shoot 1" or under, five-shot groups @ 100 yds. One of them will shoot 1/2" or less groups @ 100 yds. Either you're a lousy shot or you need a better scope/trigger on your AR.
My Yugo SKS is also the most accurate semi auto I own. It's been the value ever for the $90 I spent on it.
My Chinese SKS (which I paid more for) is a POS that doesn't shoot worth crap in comparison.
