The Rock Island Armory VR60 Semi-Auto shotgun from Armscor is designed to function just like an M-16 or AR15 and be just as reliable! This is a no-nonsense shotgun built using a conventional gas operated action set in a 7075 Aluminum upper receiver. The VR60 features a removable carry handle, polymer furniture with a hefty combat style pistol grip, and an elevated bead front sight. The precision reamed ordnance steel grade barrel is threaded to accept the Beretta/Benelli Mobile Choke system. The 5 round removable box magazine is large enough for any CQB scenario that may arise. With a railed forend you can attach a variety of tactical accessories to suite your home defense needs or equip for competition and hunting.
