So I bought a Hogue stock and fore end for my Mossberg and I really like it, feels great in the hand and shoulders really well and it's Hogue so it has that nice rubberized texture and keeps the weapon in the hand. But my Mossberg is slightly older maybe from the late 80's maybe the early 90's and the fore end moves forwards and backwards ever so slightly maybe a 1/4 of an inch if just shy of that and it does not keep the gun from functioning at all just when i'm holding it, it just moves forwards and backwards when i'm cycling it. Does anyone know of a way to maybe shim the fore end to get it tight and I have checked and I do have the nut as far as it can go.
