SHS Silenced Piston Head in the Standard Bore — the same ported design in the ordinary diameter. For conventional AEG cylinders.

The silenced piston head in standard sizing, for a gearbox running a conventional cylinder rather than a wide one.

Ports through the face give the air a route instead of a wall. What you get is a slightly softer report and a less abrupt stop as the piston reaches the end of its travel.

Behind the face sits a thrust bearing, so the spring is free to rotate under load rather than twisting against a fixed surface.

Good to know before you buy

This is the standard-diameter version. A build running a bore-up cylinder needs the bore-up head instead, and the two do not swap over.

Frequently asked questions

How much quieter is it?
Noticeable rather than dramatic. Porting takes some sharpness out of the report, but barrel, hop unit and cylinder volume all have their say too.

Which bore do I have?
Most AEGs leave the factory with a standard cylinder. Bore-up is an upgrade you would usually know about, though it is worth measuring if somebody else built the gun.

Can I reuse the old o-ring?
Fit fresh seals wherever you can. An o-ring that has taken a set is one of the more common reasons compression disappoints after a rebuild.

⚠ Standard bore, not bore-up: establish which cylinder is in the gun before ordering, because a standard head inside a bore-up cylinder will not seal and the shot simply falls away.
💡 Titan Forge Airsoft tip: If compression is the problem you are chasing, change the cylinder head pad and the nozzle seal in the same session. Browse pistons and piston heads.
