Burt Gummer first revealed this sniper rifle in Tremors 2: Aftershocks and carried it as his backup weapon throughout his time in Mexico during the film. He used the last shot of this gun with great affect in Tremors 2: Aftershocks to take out a Shrieker at long range blasting it apart. However it continued on through the cement wall wooden beams, oil barrels, an outhouse, all the way into a car through body into the engine apparently puncturing the transmission tank and continued for about five miles after that.
