Yes, I was wondring if anyone could help me. I have a Mossberg 88 maverick, and i recently bought pistol grips for the forend and rear from top advantage. I was wondering what i should do to be able to use a forend grip. Is it possible to buy a mossberg 500 tube assembly that will fit the maverick 88 ? and the forend pistol grip just slide over that assembly? i would like all the help i can get thanks.
