I just got a c93 and after shooting one time has no bolt gap. I checked the barrel pin and was able to move it half way out with 2 light taps with hammer. I'm glad for this site because I called Jeff today and ordered a new barrrel, as soon as I get it the rifle will head off to Ghillie. The rifle functioned well and seems to be built decent(straight sites , most welds are pretty good) , it just had no bolt gap. I can't wait to get this gun redone I have a couple thousand rounds ready for it!
