Patent attributes
A rear sight comprises a base member and a top member. The base member comprises a fitting portion and a base member bearing surface. The fitting portion of the base member is attachable to a firearm. The top member comprises a rear sight alignment portion and a top member bearing surface. The top member bearing surface is slidably engageable with the base member bearing surface for pivotable movement of the top member relative to the base member between lowered and raised positions. Movement of the top member away from the lowered position and toward the raised position increases the distance between the rear sight alignment portion and a barrel axis of the firearm to thereby adjust the elevation of the rear sight alignment portion of the rear sight.
