The Legends Line is now rocking the legendary Umarex Legends M3 Grease Gun. The Umarex Legends M3 Grease Gun is based on the M3A1 variation used from 1944 and beyond. Underneath the dust cover resides the bolt and its cut-away thumb charging slot. This blowback action SMG does fire from the open bolt just like the M3 firearms did. Noteworthy features include the collapsible wire stock, drop-free 60 round magazine, fixed peep style sights, and a 1,050 BB per minute rate of fire. Like other Legends SMGs, the M3 Grease Gun is powered by (2) 12-gram CO2 cartridges. Expect to shoot approximately 120 BBs for each full CO2 charge.FeaturesBased on M3A1 variantShoots .177 Caliber Steel BBsSemi or Fully Automatic Operation60 Round Drop Free Magazine(2) 12 Gram CO2 Power SourceFlip Open Dust Cover"Thumb" Cut-Away Charging Slot on BoltThree Position Manual SafetyCollapsible Wire StockPeep Style Iron SightsRate of Fire 1,050 BBs Per Minute460 FPS
