These Support Dowels slide into the trigger guard and will prop the gun up for better viewing. It works on either long guns or hand guns. I see many dealers at gun shows using just a plain piece of round wood dowel or cloths pins to prop up their guns. The Support Dowels are 8 sided which helps prevent a gun from "walking" across a shelf or table if you have a bouncy floor. They come in 1/2" and 3/4" diameters and are 3 1/2 " long. Made of hardwood.
