I use a socket on a long extension.
i think it is a 12mm.
Grizzly + Knoxx stock = Good Shotgun![]()
So Josh what you are saying is that when you grab the receiver with one hand and the rear stock with the other you can twist the two.If thats the case you have to pull out the little rubber plugs from the recoil pad unscrew the recoil pad from the rear stock and the get a long screw driver or socket and extension and tighten up the stock bolt.Don't over due it but make sure its tight.
