Cradelshooter, what caliber is the MVP you were shooting and looking at? The one I bought and have put only about 100 rounds through so far, is 5.56/ .223, it takes standard AR mags. As for the feeding issue you refer to... haven't heard about that, but didn't have a single issue with the three 30 round mags I put through mine. I tend to NOT coddle a bolt gun though, without abusing it, I do it with authority.
