A rather too quick demonstration of the Crown Model XMP-K, which is based on the SIG Sauer MPX, equipped with the Wolverine Airsoft Inferno HPA engine as shown by Spectre9mm... "The Wolverine Airsoft solenoid valve unit Inferno is incorporated into the air cocking type air gun XMP-K (SIG MPX) released from the Crown model to make it a semi-automatic and fully automatic gas gun.

The solenoid valve unit used is a solenoid valve rifle and MTW unit sold by Wolverine Airsoft.

The chamber is processed according to the magazine for Marui's standard electric gun M4. The electronic trigger unit that enables semi & full auto uses Wolverine Airsoft Spartan FCU.

Wolverine Airsoft solenoid valve unit is great! :)"
