I have both mvp patrols in 223 and 308, you have to get used to how the bolt runs, that's all there is to it, its got a different feel to them, its lose yet ive managed to fire off all 5 rounds very quickly once I figured out how, ive used your standard AR-15 pinned GI 30 rounder (people at the range are like WTF!) p mags( feels way to loose but feed surprisingly well) and the factory stock mag for 223, as well as the norinco mags from my m14 in the 308 version, they are light, I love the trigger personally, and they are NATO stamped 5.56 and 7.62, what are you going to be using this rifle for, plinking, preadator, hunting, Long range shooting, ?
