Thompson Gun In .30 Carbine
This weapon was used in the 1941 Light Rifle trials. Based around the well proven .45 ACP submachine gun, its improvements are the magazine insert and position of the stock to increase accuracy. Also to mention it has the same quick barrel change as the German MG42. The Thompson Light Rifle was a reliable platform but may have been better off chambered in a more powerful rifle round.
