Patent attributes
A mount for mounting an accessory (19) on a weapon comprises a base plate (12) with an upper surface and a lower surface, to be connected with the accessory. The base plate (12) is clamped to a rail (10) on the weapon with the lower surface engaging the rail. Two aligned first grooves (23) in the upper surface extend in the longitudinal direction of the rail and a third groove (24) in the upper surface of the base plate, extends transversely of the first grooves. First protrusions (25) on the lower surface of the accessory guidingly engage the first grooves, and a third protrusion (26) on the lower surface of the accessory located between the first protrusions engages the third groove (24) to prevent displacement of the accessory along the first grooves.
