A few months back my father in law picked up a MPR in 6.5 prc. Took it out to sight in and after 7 or 8 shots it wouldn't eject the brass from the chamber. The brass looked fine not over pressure or anything it just quit ejecting. He sends it to them and a few weeks later gets it back after they fixed something they said. He takes it back to shoot and rezero and after a few more shots the bolt starts locking up and having issues ejecting the brass again. So he sends it back and a few weeks later gets a new rifle from them. Did he just get a crap rifle or is Christensen Arm's a hit or miss sort of deal
