So something unexpected happened to me at the range yesterday, I was shooting my CZ 550 and I had just loaded it put the bolt forward and down and the safety was on as I lined up my scope I went to flick the safety off with my thumb and on release of the safety the rifle fired without anything on the trigger. No injuries other than the safety taking some skin off my thumb from the recoil , but a failure like that has me a bit shaken. Someone lightened the trigger tension on it (this was done before I owned it so I don't know how or anything like that). Has anyone had something similar occur? I'm going to take it to a gunsmith this weekend to get it looked at I tried recreating the failure (with the gun empty of course) and it wouldn't do it again (I tried about 50 times). Any advice or anything that might save me a pricey trip to a gunsmiths?
