DefRev has found a very interesting ghost ring sight system for combat shotguns. The system consists of a BAR series rear ghost ring sight and SG series fron sight. The rear ghost ring sight is fully adjustable. Almost any tactical pump or semi-auto shotgun can be upgraded with the system. The sights are made by LPA, and are being marketed by Precision Sights Int’l.
