Take it down and put a piece of that paper in the hook, and put the barrels back on. If that tightens it up and the fore end goes back on, shoot it and see if you like it. As with the tape this isn't a permanent fix but it will let you know if you want to have it fixed correctly. Which fore end attachment does your have? If the barrels are good and you like the dynamics of it get it rejointed. MKII
