The Ax-20 blaster cannon represented a specific model of compact blaster cannon. It was produced by BlasTech Industries. This particular weapon design allowed for continuous firing bursts without the risk of it becoming too hot. It featured an elongated barrel design, distinguished by an expanded section near the muzzle.
The 74-Z speeder bike, crafted by Aratech Repulsor Company, incorporated an Ax-20. This was secured on a revolving platform beneath the main structure of the vehicle. It extended outward, positioned under the control vanes located at the front. The rear of the blaster was linked via a pair of power coupling lines to a set of six power cells. Each of these cells were connected to a power cell recharging unit. The speeder bike's pilot had command over the cannon through firing mechanisms located in the right steering grip.
