So I just got the new knoxx forgrip for my mossberg today but to my dissapoitment it will not work. The tube that the forgrip sides on is about and inch and a half to short so I cant put the bolt on the end. Why would this be its for a mossberg 500. Does anyone have a thoughts of what to do? It was only worth 20$ and to ship it back to the shooting edge will cost me like $10 so there not to much point. Was thinking of sanding the front down so I can slide the bolt down to the threads. Thats all I can think to do thow. Any thoughts would be helpfull.
