Complete Reinforced Gearbox V3 QD with Micro-Contact (Rear-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 rear-wired.
