Laylax run several product lines under one roof. Prometheus covers AEG and GBB internals, most famously the EG inner barrels, alongside gearsets and motors. Nineball is their pistol line, with outer barrels and dress-up parts for the Tokyo Marui Hi-Capa. They design largely around Tokyo Marui guns, so fit on a Marui platform is usually straightforward.
What we stock
Prometheus EG inner barrels including MWS length, EG Hard and standard 13:1 gearsets, high speed and high torque motors, and Nineball Hi-Capa 5.1 fluted, 2-way and Gold Match outer barrels.
