This is an excellent example of a M1 Thompson semi-automatic rifle as manufactured by Kahr Arms via their Auto-Ordnance Subsidiary. These were produced as copies of the original war expedient M1 Thompson SMGs only in semi-automatic. This example has had a correct 10.5 inch smooth M1 type barrel installed. It has the standard Auto-Ordnance markings on both sides of the receiver with the left side marked "CALIBER .45M1". It has the correct style fixed front sight, fixed "L" type war expedient rear sight, horizontal walnut forearm, pistol grip and fixed (non-detachable) buttstock. Includes a hard plastic Thompson-branded carrying case.
