ok ordered a new barrel received it and went to install it but it only goes in about half an inch and got tight dont want to gorilla it and mess things up. The original goes in and out with no problem and asked some one else about it and was told the threads on the new barrel were max and the action might be a minimum thread tolerance.. Any one have any ideas on what i might be able to do instead of maybe calling the barrel mfg and asking them to match it up??? Thanks
