- Functional bolt catch
- Stop firing on empty & when the mag is removed
- For GATE ASTER II®-equipped platforms
If you're running an AEG or HPA build with a Gate ASTER II inside, this set will elevate realism considerably! Designed to be paired with the ASTER II Bluetooth® ETU installed in a V2 gearbox, built either as an AEG or HPA setup, the Magazine & Bolt Catch Sensor Set provides a functional bolt catch and magazine cutoff when installed, giving you maximum realism and transforming your primary into an effective training tool.
The set requires soldering to install, so we recommend it for experts and those who are handy with a soldering iron. When installed, both the bolt catch & mag sensor work with a programmable capacity limit dictated by the ASTER II, cutting off power when the magazine is empty or removed. After you've reloaded, hit the bolt catch, as you would with a GBBR or real AR-15, to bring the platform back into action.
If you need a more realistic experience and have the skills to install it, the GATE Magazine & Bolt Catch Sensor Set for ASTER II Bluetooth® ETU will change your game. Providing PTW/GBBR-like realism with the reliability of an AEG or HPA power source is a match made in heaven!

Parts Fitting
Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff.
Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.
We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!
Unique Parts
Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.
Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.
If you require help with fitting any parts feel free to get in touch with us via our Contact Us Page.
