Action Army AAP-01 Out Valve — a higher-powered release valve that opens wider and lets more gas through per shot. Also listed for Marui G18 magazines and their clones.

The output valve is what meters gas into the nozzle every time the hammer drops. The standard one is set up for the gun as it left the factory; this one is built to release more, which is what you want once the nozzle, spring or bolt have been changed and the stock valve becomes the restriction.

It is a higher-powered release valve, fully compatible with the Marui G18 and clones, so it is useful beyond the AAP-01 if you run both.

It is not a free upgrade in performance terms. More gas per shot means more gas used per magazine and a harder time keeping the chrono honest, so treat it as part of a tune rather than a bolt-on.

Good to know before you buy

Re-chrono after fitting. A higher-flow valve raises muzzle energy on its own, and a site will not take your word for it.

Gas consumption goes up. If you were getting two magazines from a fill you may get one and a half, which matters more in winter than in summer.

This is a tuning part, not a repair part. If your magazine is simply leaking, the input valve or the seals are the place to start.

A valve key is needed to fit it and is not supplied.

Frequently asked questions

What does a high-flow out valve actually do?
It opens further and releases more gas per cycle. On a gun with an upgraded nozzle or a lighter bolt, the stock valve becomes the bottleneck and this removes it.

Will it raise my FPS?
Very likely, which is why you re-chrono before you play. How much depends on the rest of the setup.

Does it fit Marui G18 magazines?
It is listed as fully compatible with the Marui G18 and clones, as well as the AAP-01.

Will I get fewer shots per fill?
Yes, expect to. More gas per shot is the point of the part.

What material is it?
Not published. Action Army state no material or weight for this valve.

💡 Titan Forge Airsoft tip: Fit this with a nozzle upgrade rather than on its own, then chrono the lot together. The rest of the platform is in AAP01 parts.
