Ok I just got my lvl 10 in. I bought it used. anyway, my problem with it is that the bolt wont go in past the breech! It stops right before the feedneck! The tip of the bolt is fater and im assuming that thats the problem. I have an E-Mag with the stock center feed body. and the stock bolt does slide in all the way.

SO what i was thinking (since i dont know how much new lvl ten bolts are just for the bolt) that i could sand the end down untill it fits? But my concern is that maybe its the body? or the bolt is supposed to be like that also if i sand the bolt down it probably wouldnt be round anymore. so i dont know what to do!
