We try to adjust our gearboxes as much as possible to allow use of the widest variety of part brands. However we still recommend to use Retro ARMS spare parts, because they are the most compatible.
We can´t recomended to use our gearboxes in Classic Army Guns due to problems with compatibility.
Gearbox installation requires technical knowledge and skills.
