The UMP-45 has a very controllable rate of fire giving it more accuracy at a longer distance compared to other SMG's.
All of these weapons are custom injection molded to very high standards in house all proudly manufactured in the U.S.A! All of which are 100% compatible with LEGO minifigures. Made of High Quality ABS plastic which is the same type of plastic that most LEGO© bricks are made of! Even all the machines and materials we use are all from the U.S.A, which not a lot of other vendors can say these days.
