Overview
The Rock Island VRBP-100 is a gas-operated, magazine-fed semi-automatic bullpup shotgun chambered in 12 gauge. Manufactured by Derya Arms of Turkey and imported by Rock Island Armory, it places the action behind the trigger to deliver a 20-inch barrel in a compact 31-inch overall package. It feeds from detachable steel box magazines shared with the VR series, uses a Beretta/Benelli Mobil screw-in choke system, and ships with interchangeable light and heavy gas pistons to cycle both 2.75-inch and 3-inch shells.

Notes
Built on the same VR-series action as the VR80, the VRBP-100 reconfigures it into a bullpup chassis with a 13-inch Picatinny top rail, folding front and rear backup sights, and an adjustable cheekpiece. Supplied with two 5-round magazines; 9-round and 19-round magazines are available.
Background
The VRBP-100 grew out of Rock Island Armory's VR-series of magazine-fed semi-automatic shotguns, repackaging the proven gas-piston action into a bullpup layout to give buyers a defensive shotgun with a full-length barrel in a maneuverable, short overall length.
