More gas, more consistency

This upgraded output valve for the Action Army AAP-01 releases more gas per firing cycle than the standard part, delivering stronger and more consistent performance. It is a popular fix for magazines that have started to feel weak or inconsistent, and a proven performance tweak for players chasing stable output in cooler weather.

Built to last

Machined from stainless steel, this valve resists the wear and pitting that eventually causes the original to leak. A precise, durable seal means dependable gas delivery shot after shot.

Broad compatibility

Designed for the AAP-01 Assassin gas magazine, it is also compatible with Tokyo Marui and variant models sharing the same fitment, making it a versatile spare to keep in your kit.

Fit it right and chrono after

Purge all gas before fitting, use the correct removal tool, and have an experienced technician handle the swap. Because output can increase, always chrono before play. Browse more upgrade parts in our airsoft accessories range, or book our Kent repair service.

Frequently asked questions

What does a high-output valve actually do?

It releases more gas on each firing cycle than the standard valve, which can lift power and give more consistent shot-to-shot performance, especially in colder conditions.

Is it compatible with Tokyo Marui magazines?

Yes. As well as the Action Army AAP-01, this valve is compatible with Tokyo Marui and variant magazines that share the same fitment.

What is it made from?

The valve is machined from stainless steel for durability and a reliable long-term seal.

How is it fitted?

It is a direct drop-in replacement. Always purge all gas from the magazine first and use the correct valve removal tool. An experienced tech should carry out the swap.

Will it work with my site or field power limits?

Because it can increase output, always chrono your magazine after fitting to confirm you remain within your site limits before play.
