Description
Army x Jag Precision x Taran Tactical International Licensed Custom 5.1/4.3/JW3/Baba Yaga Hi-Capa Series Part – Magazine Output Valve Set
This is a magazine output valve set for the licensed Army x Jag Precision x Taran Tactical International custom Hi-Capa series, covering the 5.1, 4.3, JW3 and Baba Yaga models. The output valve is the part of a gas magazine that releases gas into the pistol each time the hammer strikes it, so it is central to the pistol’s power, consistency and blowback.
Army Armament produces a wide range of Hi-Capa pistols and spare parts, including the licensed JW3 and Baba Yaga designs. Replacing a worn or damaged output valve is a common and worthwhile repair that can bring a tired magazine back to life. This set is for owners who want to service their magazines or keep spares in their kit bag.
How the output valve works
When the hammer falls, it strikes the valve knocker, which pushes the output valve open for a moment. Gas flows from the magazine into the pistol’s nozzle, firing the BB and cycling the slide. If the valve’s seals wear, or the valve is damaged by a dry-fire or a dropped magazine, you may notice leaks, weak shots or poor blowback. A fresh valve usually cures these problems.
Fitting
Removing and fitting an output valve needs the correct valve key or tool, and the magazine must be completely empty of gas first. If you are not confident doing this yourself, a technician can fit it quickly. The listing does not state exactly what parts the set contains, so please check the product image before ordering.

Compatibility
Listed for the Army x Jag Precision x Taran Tactical International licensed 5.1, 4.3, JW3 and Baba Yaga Hi-Capa series. Many Hi-Capa parts follow a common pattern, but fit between brands is not guaranteed, so check your pistol’s make and model, and compare against your existing valve, before ordering. Our range also lists the Army R501-A-80 output valve for the same series.
Care and maintenance
Always empty the magazine of gas before removing the valve. Put a drop of silicone oil on the valve’s seals when fitting, and do not overtighten it. Silicone oil on the fill valve every few fills, and storing magazines with a little gas in them, helps all the seals last longer.
Who is it for?
Owners of Army custom 5.1, 4.3, JW3 and Baba Yaga Hi-Capa pistols who want to repair leaking or weak magazines, or carry spares.
