Description
The MAXX MODEL CNC Aluminium M4T HOP-up Chamber is compatible with the Tokyo Marui MWS and the Double Eagle clone system. It offers an incredible increase in HOP performance, both in precision and reliability. It includes everything you need for installation and is compatible with most GBB HOP-up buckings.
This chamber is equipped with a unique rotary dial, which allows for precise adjustments and prevents accidental shifting from vibrations. It also has a bolt stopper to reduce the bolt carrier bounce, which eliminates the risk of double feeding. Although the MWS system is solid out of the box, this upgrade HOP chamber just pushes it to that next level of performance!
It features innovative design choices such as its C-Clip barrel lock and Taper locking sleeve, which ensure that the inner barrel is perfectly stabilised, eliminating wobble and rotation, which can hinder the performance of your replica. The overall HOP system is based on single-arm control technology, which removes the instability of dual-arm designs and provides a smoother and more precise performance.
Overall, the MAXX MODEL CNC Aluminium M4T HOP-up Chamber is a must-have upgrade for your Tokyo Marui MWS system. Its high-quality materials and manufacturing process ensure an unmatched performance when it comes to this, vs the out-of-the-box performance, and that's saying something because the standard MWS system is nearly perfect!

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.
