A
reinforced gearbox V2 by Specna Arms. The product is
intended for the installation in M4 / M16 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 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 rear-wired.
