Austrian gunmaker Johann Fanzoj took six-years to craft a custom four-barreled rifle/shotgun for a customer in the U.S. that they refer to as a “masterpiece.”
The Vierling (from the German word Vier, meaning “four”) pairs a side-by-side double rifle in hard-hitting 9.3x74mmR– a classic medium to large game round popular in both Europe and Africa — with an over-and-under 20-gauge 3-inch chambered shotgun on a single frame.
As shown in the above demonstration, the 10.12-pound firearm is set to fire four times in succession when fully loaded and ejects the spent shell casings/hulls all at once when the action is broken open. The gun uses double triggers with a push-forward switch on the comb (front for shotgun, back for rifle) to select which action they control.
The “mechanical wonder” is an exhibition grade-gun that features custom-made of Circassian walnut burl furniture and engravings of various animals mixed with ornamentation applied by the hand of a master engraver.
