Thompson T12BKT 45 ACP 10-Rd Drum - 1927-A1 Fit - Blued Steel

The Thompson T12BKT is a factory 10-round drum magazine chambered in 45 ACP, purpose-built for the legendary Thompson 1927-A1 Tommy Gun. Constructed from blued steel with a 6.75" diameter housing, this drum is the direct OEM replacement and feeds reliably in most full-auto Thompson configurations, including the 1927A-1 Deluxe models with both steel and aluminum receivers.

Each T12BKT drum ships with a drum installation device (3rd hand) and a Thompson manual to make loading and installation straightforward. The classic blued finish matches the original Thompson aesthetic, making this drum the natural choice for shooters running a modern Auto-Ordnance Thompson rifle or a faithful 1927-A1 reproduction.

Fitment note: This 10-round drum is engineered for 1927-A1 Thompson models and modern Thompson guns manufactured in Worcester, MA. It is not compatible with the Thompson M1.
