I have NIB Speedfeed 4 pistol grip stock and Knoxx "hogue" forend for the Remington 870 series. Neither have been shot with.Link to Speed Feed Stock
The Knoxx Fore-end
is NIB also, never shot, is similar to a hogue stock, it has a rubberized texture.
Trades I would consider are in priority: CQD DIETER Grip for AR15
Wilson Combat 8 round Government Mags
Ruger 22/45 Mags
