The valve is designed as a direct replacement for original Action Army AAP-01 and AAP-01C magazines.

Compatibility is also reported with certain Tokyo Marui, WE and KJ Works Glock-type GBB magazines. However, construction details, threading and valve-seat dimensions may differ between magazine models and versions, so compatibility does not necessarily extend to every variant.

This is a magazine filling valve and must not be confused with the gas output valve, which is operated when the pistol fires.
