Complete Reinforced Gearbox V2 QD (Front-Wired)

Complete Reinforced Gearbox V2 QD (Front-Wired) 

A reinforced gearbox V2 by Specna Arms. The product is intended for the installation in M4 / M16 replicas. The frame was adapted for use with 8 mm slide bearings. The manufacturer has taken care to reinforce the most vulnerable spots of the construction, which enables its use with more powerful springs. Gearbox V2 is an excellent solution for people seeking a good-quality shell at a reasonable price. The gearbox features a quick spring change system compatible with CORE and ONE series replicas by Specna Arms.

The Enter & Convert 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 steel, last tooth; a polymer, air-sealed piston head; a cylinder head with a soft dampener; an aluminum, type 0 cylinder; a polymer nozzle and a 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.
