Complete Reinforced Gearbox V3 QD
with Micro-Contact (Front-Wired)

A reinforced gearbox V3 by Specna Arms. The product is intended for the installation
in AK replicas. The shell was adapted for use with 8 mm slide and ball
bearings. The manufacturer has taken care to reinforce the most vulnerable
spots of the construction, which enables its use with more powerful springs.
Gearbox V3 QD is an excellent solution for people seeking a good-quality frame
at a reasonable price.

The quick spring change system
enables a rapid and simple adaptation of replica’s power to the
conditions that can be encountered on the airsoft battlefield. The adaptation
does not require the disassembly of the entire gearbox. The user does not even
have to have specialist tools on hand or spend time in a workshop. The first
step is to take out the gearbox from the replica’s body. Afterwards, the user
needs to pull out the spring along with the guide through the opening in the
rear wall of the shell. The process itself lasts only mere seconds.

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, ball bearing spring
guide. The exchanged configuration can generate a muzzle velocity of 400 – 420
FPS, depending on the replica. 

In order to improve the trigger
reaction time and the lifetime of LiPo batteries, the shell was modified for
use with the included micro-contact instead of standard contact plates.

This version is front-wired.
