Complete Reinforced Gearbox V2 Mod2 with Electronic
Contact (Rear-Wired)
A complete, reinforced gearbox version 2 dedicated for M4 / M16 replicas.
It is an ideal solution for people wanting to purchase a good-quality gearbox
at a reasonable price. The frame has been adapted for the use with 8 mm slide
and ball bearings and thanks to the construction reinforced at the most
vulnerable spots it can be used in combination with more powerful springs. The
gearbox features a quick spring change system compatible with CORE and ONE
series replicas by Specna Arms.
The Enter & Convert system enables a rapid and quick adaptation
of the power of the replica to conditions expected on the airsoft playing field
without the necessity to disassemble the entire gearbox and therefore having
the access to a workshop or a set of special tools. Once the gearbox has been
taken out of the replica’s body, the process of spring change lasts literally
mere seconds. The spring along with the guide needs to be taken out
through the opening in the rear wall of the frame.
Following parts are included inside: reinforced 18:1 steel gears; an m110
spring; a lightweight, polymer piston with a full steel strip; an aluminum,
bearing-mounted, air-sealed piston head; an aluminum cylinder head with a soft
dampener; an aluminum, chrome type 0 cylinder; a polymer, air-sealed nozzle and
a metal, bearing-mounted spring guide. The exchanged configuration can generate
a muzzle velocity of 400 - 420 FPS, depending on the replica.
The characteristic feature of this frame is that it is adapted for the
included in the set electronic contact that oversees the operation of the
gearbox, which significantly improves their trigger reaction and extends the
lifetime of LiPo batteries.
This version is rear-wired.
