I was having an issue with my CZ 455 rifle. The bolt was just sliding freely out of the receiver without pulling the trigger to release it. I found that a pin had shimmied out of one side of the sear assembly allowing it to lower slightly which in turn allowed the bolt to move freely out of the receiver. I put the pin back in place and put locktite on it to hopefully prevent it from comming out again. This is the second time the pin came out of place on me. Post your links and comments on how to improve the CZ 455 below.
