Maxx Model CNC Aluminum Hop-Up Chamber for Wolverine MTW Series Airsoft Rifles (M4W)

Take your Wolverine MTW’s accuracy and consistency to the next level with the Maxx Model CNC Aluminum Hop-Up Chamber M4W — a precision-engineered masterpiece crafted for elite Airsoft performance. Designed for the Wolverine MTW Milspec, Forged, Billet, and MTW-9 platforms, this hop-up chamber is built from solid aircraft-grade aluminum and tuned for perfection down to the smallest detail.

Precision Engineering Meets Unmatched Performance

Machined from a solid block of 6061 aircraft aluminum, the Maxx Model M4W hop-up chamber is built with tight tolerances that deliver superior air seal, improved shot-to-shot consistency, and long-lasting durability. The CNC machining process ensures flawless alignment between your inner barrel and nozzle, minimizing air loss and keeping every BB on a tight trajectory.

The rotary dial design allows for fine hop-up adjustments — giving players the ability to precisely tune backspin and range depending on BB weight, field conditions, or playstyle. Whether you’re running R-Hop, Flat-Hop, or Standard-Hop, the re-engineered lever and nub system ensures every shot leaves the barrel straight, accurate, and stable.

Optimized for Wolverine MTW Compatibility

Purpose-built for the Wolverine MTW engine’s M4 nozzle length, this hop-up chamber seamlessly integrates with your HPA setup. It’s also fully compatible with most aftermarket soft or hard buckings, allowing you to customize your setup without losing FPS or experiencing feed drops.

The CNC Delrin Locking C-Clip ensures a rock-solid barrel lock, completely eliminating wobble or twist. Three compression springs—strategically placed at the top, bottom, and center—maintain perfect alignment and air-tight compression, ensuring your hop-up sits straight and true every time you reassemble your rifle.

Smart Features for Pro-Level Reliability

The Maxx Model M4W comes loaded with thoughtful design elements for advanced performance and reliability. Its BB Latching System prevents BBs from dropping out when changing magazines — a common frustration during reloads. Simply release the latch manually when you need to clear the chamber.

The included CNC Brass Side Wings and Acrylic Side Covers ensure smooth, frictionless operation within the receiver. A CNC Aluminum Rotary Dial Knob gives you instant, tool-free hop-up adjustments even during gameplay, while the CNC Delrin Locking C-Clip secures the barrel in place with unmatched stability.

Additionally, the interchangeable Inlet Adaptor (OD11mm) guarantees a perfect fit with HPA nozzles, ensuring consistent alignment without wobble — an essential feature for maintaining consistent FPS and air efficiency.

Performance Tested & Proven

During field testing, users have reported FPS gains between 10 to 30 FPS over standard hop-up setups thanks to the improved air seal and alignment. Every design choice in the M4W hop-up chamber contributes to more consistent air pressure, cleaner backspin, and better overall range and precision — giving you a measurable edge on the field.

Note: Professional installation is strongly recommended to ensure perfect fit and function. Some modification may be required depending on your build.
