I bought a carbon volquartsen barrel for my magnum research lite 22lr. I put it on put my spectre II on it and didn't even have close to enough adjustment it was shooting 24ish inches to the right and also 12-18 inches high. I took the can off and it shot great. I took the can apart and couldn't find any lead smears or damage to the baffles. I put the can on my 77/22 and it shots great there. I talked to volquartsen and they said to send it in that the threads are probly not lined up correctly with the barrel. Anybody ever have anything like this happen??
