I have a Burgundy junior lockdown with a 4 date code that the cap will not screw on. I have switched the cap with a similar Grey model and that cap screws onto the Burgundy barrel well. The Burgundy cap will barely catch the threads on the Grey barrel. I removed the section and the cap screws right on. I've checked the widths of both caps and they are the same. The sections are the same also. I have measured from the cap edge to the inner cap and it is the same on both caps. It seems to me that the inner cap is the problem but I can't figure it out. Any suggestions? Is it a relatively straight forward fix or should I just get a new cap?
