A device for fixing an additional device, such as a scope or laser sighting device, to a firearm free of play and able to accommodate the ever-changing (recoil and spring-back) forces that occur on the engaging mechanism of the fixing device. In addition to a recoil lug contacting a first stop surface of a first groove, a further adjustable stop is provided, engaging a stop surface in a different groove in a direction opposite, along the line fire, to the first stop surface. |
