Description
Army Custom 5.1/4.3/JW3/Baba Yaga Hi-Capa Series Part – Disconnector (R501-A-50)
This is a replacement disconnector (part R501-A-50) for Army Custom Hi-Capa series pistols, including the 5.1, 4.3, JW3 and Baba Yaga models. The disconnector is a small but important part of the trigger mechanism.
This Army Custom part is listed for the 5.1, 4.3, JW3 and Baba Yaga Hi-Capa series pistols, a family of popular, highly customisable gas blowback sidearms. Keeping a spare of a part like this means a broken or worn component does not keep your pistol out of action for long.
What the part does
In a Hi-Capa-pattern pistol, the disconnector works with the trigger and sear so that the pistol fires only once per trigger pull and cannot fire until the slide has returned fully forward. When it wears, you may see problems such as the hammer following the slide down, the pistol failing to reset, or doubling.
Replacing a worn disconnector is one of the first things a tech will check when a Hi-Capa’s trigger starts behaving oddly, and it is an inexpensive part to keep in your spares.
Fitting
Fitting a disconnector involves stripping the Hi-Capa’s frame and trigger group, so follow the exploded diagram for your pistol carefully. Note the orientation of the old part before removing it. After reassembly, function-check the trigger, reset and safety several times with the pistol unloaded before using it.

Compatibility
Listed for Army Custom 5.1, 4.3, JW3 and Baba Yaga Hi-Capa series pistols. 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 part, before ordering.
Care and maintenance
Before fitting, clean the area of the pistol where the part sits and remove any old dirt or grease. Use only silicone-based lubricants on gas-system parts and seals, and avoid petroleum-based products.
If you are not confident stripping a Hi-Capa, have the part fitted by an experienced technician. After fitting, test the pistol carefully at a safe backstop before using it in a game.
