The patent pending Chamber-View® product for shotguns is designed to fit most currently available side ejection semi-auto and pump style shotguns. These include models from the top seven manufacturers: Beretta USA, Benelli, Browning, Franchi, Mossberg, Remington and Winchester.
The tapered design allows the Chamber-View® to fit in most .410, 20 and 12 gauge shotguns. It has also been tested and will fit into some discontinued shotgun models not readily available.
