These are a higher end gear. 13:1 ratio gears are applied when seeking a high ROF (rate of fire) build. *please note your blaster model in purchase/cart notes. Brands may vary from time to time but the quality will remain high end. These do not come with pinion gear or anti reverse latch.
These nylon gearboxes are top quality, If you are upgrading your blaster you may as well pimp it out with this nylon gearbox. There are inferior knockoffs of these gearboxes but we only stock the genuine Singularity brand.
These come with bearings, trigger, springs and screws. *Please note motor mount, trigger switch cover and spring guide are not included. We are working on printing nylon ones currently, however stock ones can be used.
The UMP has a rock solid nylon shell, mag and stock. For some reasons they only sell the shell so we retrofit a Gen 8 gearbox to them. This requires some rewiring and cutting and grinding to make it work. Given the robust shell and outstanding performance of the Gen 8 gearbox, this is one serious blaster.
Gen 8 spring retainer for plastic/nylon gearboxes. This spring retainer replaces the plastic stock part.
It is fitted with bearings to help reduce the stress on the gearbox when the spring twists under compression.
