The Auto-Ordnance Thompson Long Gun drum magazine is a factory replacement designed for Thompson Long Gun models chambered in .45 Auto, with a 50-round capacity. Manufactured entirely in the US from steel with a blued finish, this drum magazine is made to the exact specifications of the original factory drums. The drum diameter measures 6.75 inches and includes a 3rd hand installation device for simplified loading and installation.
This drum magazine functions in semi-automatic and most full-auto Thompson Long Gun models, ensuring reliable fit and operation. It is specifically engineered for Thompson 1927-A1 model rifles chambered in .45 ACP. The magazine will fit modern Thompson guns manufactured in Worcester, MA and Greeley, PA, but is not compatible with Thompson M1 models (military versions) or Thompson guns made in West Hurley, NY or before 1990. This drum magazine delivers the historical authenticity and practical 50-round capacity that defines Thompson rifle accessories.
