Abstract:
1. A bore periscope for looking down the bore of a firearm comprising, in combination: (a) a housing adapted to fit partially within the breach of a firearm, the housing containing an optical path extending from a first opening to be concentrically aligned with a bore in a barrel of the firearm to a second opening located outside the breach of the firearm; (b) a conical inwardly tapered tip extending around the first opening of the housing, the tapered tip having narrow slits around its periphery which appear as crosshairs when viewed from the second opening of the housing; and (c) a plurality of mirrors placed within said optical path within said housing in spaced apart relation such that a user looking in the second opening can view a reflected image appearing as though he was looking out the first opening, down the bore in the barrel of the firearm.
