I just got to get my second G3c out and shoot it, put just under 50 rounds through it and no failures and real accurate. However while I was cleaning it I found a small nick on the underside of the feedramp. The top of the ramp is smooth all across but just underneath the bottom edge there is a nick. will this cause trouble in the future and get worse or not? I ain't gonna worry if it won't get worse cause the gun shoots great. Thanks for any help
