Hi all , just go a c93 and I'm new t roller locked actions but I understand the workings. My question, this gun had almost no bolt gap (.003") right from the start. I fired 120 rounds through it with 2 FTE in the first 20 or so rounds, the rest cycled flawlessly and the gun shot well.Accuracy was on par with my friends Stag arms AR. I installed +4 rollers, still no gap. Should I get a new locking piece or does the barrel need repressed like I'm reading about these rifles. The locking piece is worn some but I have no experience to know how much. Does the locking piece acount for that much gap if its worn? I will not send this gun back to Century to let them work with it becuase besides the bolt gap issue and ugly refinish on the stock the rest of the gun seems ok. I don't want a dfferent rifle from them. Thanks for info guys , great site.
