Then there is an amp, that is on the side of the tube, coming from the amp is three wires that lead to the next part, the amplyfier, a series of three prongs sticking just past the muzzle of the grenade launcher creating a plasma field to energize the shell. The last part is a desiginater scope, for easy aiming on moving targets.
