Maxx Model Hop-Up Chamber

This unit is designed for standard Tokyo Marui, G&G, and KRYTAC M4/M16 AEG platforms using a Version 2 gearbox. Before purchasing, ensure your air nozzle length is between 21.00mm and 21.25mm to guarantee proper feeding and air seal.

The BB latching system is designed to prevent BB spillage during reloads, but it can be sensitive to magazine spring tension. It works best with high-quality mid-cap magazines; some very loose-fitting or low-quality magazines may require a slight adjustment to the latch mechanism for optimal feeding.

Yes, the chamber is engineered for versatility. It includes multiple nub options specifically designed to accommodate standard hop-up setups, as well as R-hop and Flat-hop configurations, allowing you to fine-tune your trajectory regardless of your bucking choice.

While the installation is straightforward, it does require disassembling the front end of your AEG. If you are comfortable opening your airsoft gun to access the barrel and hop-up assembly, you should find this a manageable upgrade.

The primary advantage is structural rigidity. Unlike plastic units that can flex or wobble under pressure, this CNC-machined aluminum chamber provides a consistent, airtight seal that significantly improves shot-to-shot consistency and accuracy.
