Abstract: A system for attaching a firearm accessory to a sight base including a first bore in the sight base, a second bore in the accessory body and a bushing inserted into the second bore. A bushing is inserted into the second bore and is held in place with one or more protrusions located on the sight base near the first bore and/or a screw inserted into a bore in the bushing. The bushing allows the accessory body to rotate in a plane that is perpendicular to the first and second bores. A screw inserted into a third bore that communicates with the second bore allows a screw to engage the exterior surface of the bushing featuring grooves that define positions to which the accessory body can be rotated. The accessory body's rotation can also be stopped using a groove on the accessory body that is engaged by another protrusion featured by the sight base.
