Abstract
A gun sight assembly including a body to be held against a surface of a gun, a sight carried by the body, an anchoring part received within a dovetail groove in the gun, and a threaded fastener extending through an opening in the body and threadedly connected to the anchoring part and operable to pull the anchoring part toward the body in a manner tightening the anchoring part against converging side walls of the dovetail groove and tightening the body against the surface of the gun.
Claims15
An aiming device for a gun, which gun has a surface containing a dovetail groove with converging side walls, said aiming device comprising:
- a rigid body part to be held against said surface of the gun;
- a sight carried by said body part to be viewed by a user in aiming the gun;
- an anchoring part received within said dovetail groove between said converging side walls thereof, and in engagement with both of said converging side walls;
- a threaded fastener extending along an axis through an opening in said body part and threadedly connected to said anchoring part and operable by rotation relative to both of said parts to pull the anchoring part toward the body part in a manner tightening the anchoring part against both of said side walls of the groove and clamping said body part rigidly between said fastener and said surface of the gun to locate the sight relative to the gun;
- and
- means on said body part and said anchoring part interfitting in a relation preventing the body part from turning about the axis of said fastener relative to the anchoring part.
