A small, easy sidearm. The 100mm Crazy Jet barrel is cut for the 4.3's short slide and pairs with the AIP bucking for a steady hop. The AIP output valve stops the magazine from leaking gas, the most common Hi-Capa problem. The metal mag catch and trigger ring fix the two plastic parts that wear out first. Example build by LoadoutLab. Every part is listed by its shop as made for this gun.
