Crisp, reliable semi-auto

The Guarder Cut Off Lever V2 is a reinforced replacement for the standard cut off lever inside Version 2 airsoft AEG gearboxes. This small part controls semi-auto timing, interrupting the circuit after each cycle so you get one clean shot per trigger pull.

Built to resist wear

Made from hardened, reinforced metal, it stands up to the repeated mechanical cycling that wears out softer zinc or alloy stock levers. That matters most on upgraded builds where stronger springs, high-torque motors and high rate of fire all pile extra stress onto the fire control parts.

Fixes common semi-auto faults

A rounded or bent lever is a frequent cause of double-shots, dead trigger in semi, or a gearbox that runs on when it should stop. Fitting this Guarder lever restores correct timing and predictable trigger response.

Direct fit for V2 gearboxes

It drops straight into Tokyo Marui spec Version 2 gearboxes used in most M4, M16 and other V2-based rifles, replacing the OEM lever with no modification. As fitting involves opening the gearbox, our Kent repair workshop can install it and re-time the gearbox for you. See more airsoft internal parts in our range.

Frequently asked questions

What does the cut off lever do?

The cut off lever works with the sector gear and trigger contacts to interrupt the circuit after one cycle, so the gun fires a single shot per trigger pull in semi-auto. Correct timing here is what makes semi feel crisp and predictable.

What problems does a worn lever cause?

A rounded or bent lever leads to double-shots, failure to fire in semi, or the gun running on when it should stop. Swapping to this reinforced Guarder lever restores clean, reliable semi-auto behaviour.

Which gearboxes does it fit?

It is made for Tokyo Marui spec Version 2 gearboxes, which are used in most M4, M16 and many other V2-based airsoft rifles. It drops in as a direct replacement for the OEM lever.

Do I need this if I have upgraded my AEG?

It is especially worth fitting on tuned builds. Higher spring tension, stronger motors and high rate of fire all put extra stress on the lever, and the hardened Guarder part is far less likely to wear or break than a soft stock item.

Can you fit this for me?

Yes. Replacing a cut off lever means opening the gearbox, so if you are not comfortable doing that our in-house Kent workshop can fit it and re-shim and re-time your gearbox at the same time.
