Umarex USA Legends M3 Grease Gun .177 BB CO2 30-Rd Semi/Full-Auto Air Rifle

The Umarex Legends M3 Grease Gun is a .177 BB air rifle that faithfully replicates the iconic WWII-era M3A1 "Grease Gun" submachine gun in a high-energy, CO2-powered package. Built on a metal receiver and barrel assembly with a realistic grip and stick-style frame, it brings authentic submachine-gun handling to backyard plinking and collector display.

This Legends M3 shoots .177 caliber steel BBs in either semi-automatic or fully automatic mode via a selector switch, with a working blowback action and a live-action bolt that cycles with every shot. The hinged dust cover opens like the original, and the fixed iron sights echo the M3A1 sight picture. A 30-round drop-free magazine keeps the BBs fed, and the gun is powered by two 12-gram CO2 cartridges housed inside the stick magazine.

Rated at 415 fps with a cyclic rate of fire around 1,050 rounds per minute in full-auto, the Legends M3 weighs approximately 7.7 lbs for a substantial, real-gun feel. It's a perfect pick for collectors of WWII replica hardware and airgun enthusiasts who want a fun, full-auto-capable replica BB rifle. Steel BBs and CO2 cartridges are sold separately.
