The Standard Manufacturing 50-round drum magazine for .22LR is purpose-built for the G4S Tommy Gun, delivering reliable ammunition capacity for high-volume shooting sessions at the range or during recreational plinking. Rimfire shooters who want to maximize trigger time between reloads will appreciate a drum that's engineered specifically for this platform—no guesswork about compatibility or feeding issues.
Built from machined aluminum, this drum magazine is designed for durability and dependable operation run after run. The robust construction means it'll handle the demands of regular shooting without the premature wear you might see in lesser designs. Whether you're working through case lots at the range or just enjoying the Thompson's classic appeal, a quality drum keeps you shooting longer.
Feeding .22 LR rimfire ammunition, the drum accepts a full 50 rounds—a substantial capacity boost over standard stick magazines. That translates to fewer mag changes and more time behind the gun, which matters whether you're sighting in, training, or just having fun with one of America's most iconic designs.
