Umarex Airguns Legends M1A1 Full auto BB Gun

The Umarex Legends M1A1 Full-Auto BB Gun is a faithful, full-metal replica of the iconic Thompson submachine gun — the legendary "Tommy Gun" of WWII fame. Powered by a 12g CO2 cartridge and firing steel BBs at up to 435 fps, the M1A1 delivers an authentic shooting experience that's perfect for backyard plinking, target practice, and collecting.

Authentic WWII Replica

Umarex's Legends series is built to replicate the look, feel, and handling of iconic historical firearms with exceptional accuracy. The M1A1 features a full-metal receiver, a real wood stock and foregrip, and working controls including a functional bolt that cycles with each shot. The weight and balance closely mirror the original Thompson, making it a favorite among WWII history enthusiasts and airgun collectors.

Full-Auto and Semi-Auto Fire

The M1A1 fires in both full-auto and semi-auto modes, selectable via the original-style fire selector. Full-auto mode delivers a realistic cyclic rate that empties the 30-round drop-free magazine quickly — making it genuinely fun for plinking sessions. Semi-auto mode conserves CO2 and BBs for more deliberate target practice.

CO2 Powered for Consistent Performance

A single 12g CO2 cartridge powers the M1A1, providing consistent velocity and reliable cycling across the full magazine. CO2 cartridges are inexpensive and widely available, making the M1A1 economical to shoot. The drop-free 30-round magazine loads quickly and drops free for fast reloads.

Safe for Backyard Use

At 435 fps with steel BBs, the M1A1 is powerful enough for serious target practice and pest control at close range, while remaining safe for backyard use with a proper backstop. It's an ideal training tool for new shooters learning firearm handling fundamentals in a low-cost, low-recoil platform.
