A view down range over the gun shows the grenade launcher's auxiliary targeting sight (on the right). Will is just visible in the distance in front of the first test target - a shed that is jokingly referred to as a "hostile meth lab."

The select fire single shot modification is achieved in part by the addition of a saw-tooth element that fits above the bolt slide to interrupt the auto blow back feature.

The first test target (a simple shed - see inset) is obliterated by a well laid round fired in single shot mode.

Moments later, HE rounds find the target and set off the extra charges placed in the vehicle for added explosive effects.
