Technical specifications

The Ra-Tech trigger box is manufactured from steel for maximum durability. The part features a black-grey finish that matches the standard WE AR series components. The steel construction offers superior resistance to wear compared to other materials. All trigger components such as hammer, sear, and disconnector are included in this complete set. Installation is done using the standard trigger pins of your lower receiver.

Compatibility and application

This trigger box is specifically designed for WE AR series GBBR replicas and works with both closed bolt and open bolt systems. This makes the part suitable for various WE M4, M16, and HK416 models. Installation requires technical knowledge of GBBR internals – you must be able to disassemble the lower receiver and remove the trigger pins. It is recommended to also check the hammer spring tension during installation for optimal operation.
