Isn't this the same as the LAW that was used in training in the Army in the early 1970's? What kind of gun was the LAW used then? I remember shooting one in training but don't recall the make and model.
To those that are interested, Guns & Ammo on main street Moss Point(613) has a 20mm VKT magazine fed anti-tank rifle on a tripod.
He also has cases & dies to make up the 20mm round.
