Umarex Legends MP trigger part

This is part #1-21 from the 5.8325X version of the Umarex Legends MP CO2 BB gun. This part is missing from the 5.8325 version distributed in many European countries which have restrictions on BB guns.

To be installed behind the internal safety lever (part #1-16). The gun must be disassembled, there are a couple of good videos on YouTube for this.
