"Experimental Automatic Rifle" “When a submachine gun tried to become a battle rifle.” Thompson . 30 Caliber Autorifle (Experimental 12/43) The Thompson . 30 Caliber Autorifle was a one-off experimental prototype developed in December 1943. The project explored the possibility of converting the well-known Thompson Model 1928 platform into a weapon chambered for the full-power . 30-06 M2 cartridge. To achieve this, engineers significantly modified the original design: Lengthened and reinforced receiver Heavy, extended barrel Large tubular recoil spring housing at the rear Modified magazine derived from the M1918 Browning Automatic Rifle Adaptation of the Blish-lock operating principle for higher-pressure ammunition The prototype was reportedly built to demonstrate how existing Thompson production tooling might be adapted for a more powerful automatic rifle role. Historical Context By late 1943, the U. S. Army was already fully equipped with the M1 Garand and the BAR. However, wartime experimentation continued in search of improved or simplified automatic infantry weapons. The . 30 Caliber Thompson Autorifle was never adopted. The design proved heavy, mechanically complex, and ergonomically awkward compared to the established BAR. With the war effort focused on mass production and logistical stability, the project remained a single experimental example. Today, it stands as a rare and fascinating example of late-WWII American firearms experimentation — a true mechanical hybrid bridging submachine gun and battle rifle concepts.
