Specna Arms Reinforced V3 QD Gearbox Shell with Micro Contact Front Wired

The Specna Arms Reinforced V3 QD Gearbox Shell with Micro Contact Front Wired is a reinforced Version 3 gearbox shell that has been specially developed for AK airsoft replicas. Thanks to its robust construction, 8 mm bearing seats, the Quick Spring Change (QD) system and the integrated micro-contact trigger, this gearbox provides an excellent basis for both upgrades and replacing an existing gearbox.

This version is suitable for front-wired configurations.

Reinforced V3 gearbox for AK replicas

The gearbox shell is manufactured with additional reinforcements at the most vulnerable points of the structure. This makes the gearbox more resistant to higher loads and suitable for use with more powerful springs.

Specna Arms combines a durable design with excellent value for money.

Quick Spring Change (QD)

The integrated Quick Spring Change system allows the main spring to be replaced quickly without having to dismantle the entire gearbox.

Once the gearbox has been removed from the replica, the spring and spring guide can be removed via the rear of the gearbox. This allows the spring tension to be adjusted to suit the playing field within a matter of seconds.

Micro-switch for improved trigger response

Instead of traditional contact plates, this gearbox uses a micro-contact trigger. This system responds more quickly to the trigger movement, reduces wear on the electrical contacts and helps to extend the service life of LiPo batteries.

This makes the replica feel more responsive when firing.

Practical insights

A reinforced V3 gearbox with Quick Spring Change is particularly popular amongst players who regularly switch between different FPS limits. The combination of a reinforced shell and a micro-contact switch also makes this gearbox ideal as the basis for high-performance upgrade builds where reliability and fast trigger response are key.
