Umarex Legends Thomson A1M1 4.5mm

This well-made replica of the Thompson M1A1 submachine gun can shoot in both semi-automatic and fully automatic fire modes. The metal frame gives it a similar weight to the original. The buttstock and the foregrip are made of polymer.

The gun is powered by two 12g CO2 cartridges, which must be placed inside the magazine. It can hold up to 30 steel BBs in .177 caliber 4,5 mm. The Blowback system makes shooting much more realistic. The manual safety is located above the pistol grip.

This CO2 powered WW2 submachine gun can shoot BBs with muzzle velocity of up to 136 m/s.
