Just got a new m&p 15 sport 2. My rifle is jamming and bending rounds. When I first received it I field stripped it, cleaned it and oiled it, like it says in the manual. It would not feed a round when you first loaded, round gets stuck and bent, its hard to pull it out with charging handle. If it does feed then after firing, next round would get stuck. I loaded like it says in the manual pull the charging handle, press the bolt catch, return charge handle and lock it, set to safe, insert magazine, release bolt catch. This happens with 3 pmag genm2 magazines. The ammo that i am using is PMC x-tac 55 grain FMJ. I have attached pics of bent rounds. I have shot about 90 rounds thru it and this happened with 20 rounds. Any one alse have this issue or know what could be causing this. I have contacted Smith and Wesson and waiting for reply from them if I should send it in for repair.
