This mount set contains two mounts and are usable for any gun accessory, such as flashlights, that have a diameter of 1-inch. The mount will attach to the common Weaver/Picatinny style rail to hold the light or gun accessory of your choosing in place on your rifle. Comes with one Allen wrench.
While you could mount a 1-inch tube rifle scope to a low powered BB gun, the clamp was not designed to hold an optical see-through device. It is intended for accessories that do not have to hold a precise zero.
