Some airsoft players gleefully installed the Wolverine BOLT M HPA Engine on the Silverback Airsoft SRS A3 sniper rifle after it got released. Heavy Metal Airsoft shows you how easy it is to install it... "Installing the Wolverine Bolt M HPA engine in my Desert Tech SRS was super easy and really the ultimate upgrade for this replica."
