ZCI CNC Gear Set 14:1

Built for speed, this ZCI 14:1 gear set drops the ratio to spin the gearbox faster for a higher rate of fire and snappier trigger response. It fits the common Version 2 and Version 3 gearboxes in M4, AK and SMG platforms, so it suits a huge range of popular AEGs.

CNC steel construction

Heat-treated, CNC-machined steel gears hold precise tolerances and cope with the stresses of a high-speed build. Careful machining keeps them running true and helps reduce noise at high RPM.

Speed potential

With an M120 or lighter spring the 14:1 set can push toward 40 rounds per second on a well-tuned setup. A recommended spring range of M110 to M150 keeps things sensible, so match the spring to your target rate of fire.

Build it right

High-speed builds need correct shimming, a strong motor and a suitable battery to get the best from these gears. Our airsoft repair workshop in Kent can build it for you, or browse more airsoft accessories.

Frequently asked questions

What does a 14:1 ratio do?

A lower ratio like 14:1 spins the gearbox faster, giving a higher rate of fire and snappier trigger response than a standard 18:1 set.

What spring should I run?

A recommended range of M110 to M150 keeps it sensible. With an M120 or lighter spring a well-tuned setup can push toward 40 rounds per second.

Will it fit my gun?

It fits the common Version 2 and Version 3 gearboxes used in M4, AK and SMG platforms. Check your gearbox version before ordering.

Do I need other upgrades?

High-speed builds need correct shimming, a capable motor and a suitable battery. Our Kent workshop can build it for reliable results.

Is there an age or UKARA restriction?

No. These are internal spare parts with no age restriction and no UKARA requirement.
