I have a CZ 712 utility, I have the Nordic Comp +3 extension tube. The problem I have is that the nut that holds the forend in place doesn't seem to have enough thread on the mag tube to grip. It screws on fine (a little wobbly) and snugs against the forend fine.......but if you put some pressure on it it comes loose. This is a problem because this holds everything together. After shooting 7 rounds thru it the nut came loose and I couldn't get the extension to sit right. Any ideas how to fix this?
Thanks,
Frank
