Specification

What this part is

This is a B-Grade boneyard AEG cylinder in brass, with porting (a vent hole) machined into the wall. Ported cylinders reduce effective air volume and are usually matched to shorter inner barrels, making this a handy budget internal for tuned builds.

Condition and honesty

As a used or salvaged part, the bore may show wear, marks or minor scoring. It is sold as spares or for repair with no warranty, so it suits builders who can inspect it and confirm it seals well with a fresh piston head and O-ring.

Compatibility and porting

Ported cylinders should be matched to barrel length for correct cylinder-to-barrel volume. Work out your build ratios before fitting to avoid over- or under-volume issues.

Where it fits

It commonly suits version 2 and version 3 gearbox builds. Browse our airsoft accessories for pistons, heads and nozzles to complete the air seal.

Fitting help

Our Kent repair workshop can build and test the gearbox if you would rather leave the tuning to us.

Frequently asked questions

What does ported mean?

A ported cylinder has a hole (port) that reduces the effective air volume. It is generally matched to shorter inner barrels for correct air-to-barrel volume.

Which barrel length suits a ported cylinder?

Ported cylinders are typically paired with shorter inner barrels. The exact match depends on your build, so calculate cylinder-to-barrel volume before fitting.

What condition is it in?

It is a B-Grade boneyard part. It is used or salvaged and may show wear or marks inside the bore. It is sold for repair with no warranty.

Do I need a new piston head and O-ring?

For a good seal you should check the piston head and O-ring condition. Worn seals will reduce compression regardless of the cylinder.

Is it returnable?

Boneyard parts are sold as-is with no warranty. Please inspect the bore before use, as salvage spares are not covered by standard returns.
