Umarex Legends M3 Grease Gun .177 Caliber Full-Auto BB Gun

Based on the legendary M3A1 Submachine Gun used by American troops from 1944 until the 1990s, the Umarex® Legends M3 BB Gun delivers a ton of full-auto fun. Powered by (2) 12-gram CO2 cylinders, the M3 BB Gun is capable of emptying a full 60-round mag in just seconds. Of course, you can flip it over to semi-auto mode if you want the fun to last a little longer.

It fires from an open bolt just like the original SMG did, and comes complete with a collapsible wire stock, fixed peep-style sights, and a 3-position manual safety. For backyard fun, you can't beat it.
