What this part does

The SHS V3 tappet plate is a core part of an AK pattern gearbox feeding correctly. Driven by the sector gear, it moves the air nozzle forward and back with the piston to chamber a BB and seal the nozzle for every shot, so a sound plate is essential for reliable feeding.

Build and materials

It is made from strong nylon-reinforced polymer designed to resist the repeated loads inside a working gearbox, which is why it is a dependable choice for servicing and rebuilds.

Who it suits

It fits Version 3 gearboxes used in AK pattern and similar AEGs, making it a straightforward replacement for a worn or damaged plate.

Fitting and support

Fit it with a healthy tappet spring for consistent feeding. If you would prefer expert help, our Kent airsoft repair workshop can rebuild your V3 gearbox, and related parts are listed under airsoft accessories.

Frequently asked questions

What does this tappet plate do?

It drives the air nozzle back and forth in a Version 3 gearbox, chambering each BB and sealing the nozzle so the shot fires with full air.

Which gearbox does it fit?

It fits Version 3 gearboxes, used mainly in AK pattern AEGs and similar rifles. Check your gearbox version before ordering.

What is it made from?

Nylon-reinforced polymer, chosen for strength and durability so it can cope with the repeated loads inside a working gearbox.

Will it fix feeding problems?

A cracked or worn tappet plate is a frequent cause of misfeeds, so a fresh SHS plate often restores reliable feeding in a V3 gearbox.

Should I replace the spring too?

The plate needs a healthy tappet spring to return correctly. Replacing both together is good practice during a rebuild.
