CNC Aluminum Hopup Chamber for ASG EVO

The CNC Aluminum Hop-up Chamber EVO by Maxx Model is a high-performance upgrade built specifically for the ASG CZ Scorpion EVO-3 (2018 and newer) airsoft rifles. If you're serious about precision, this chamber delivers top-tier consistency and performance for every shot.

Machined from aircraft-grade 6061 aluminum and brass, the EVO chamber features tight tolerances, ensuring perfect alignment with no movement, air leaks, or instability during operation.

Key features include:

• A precision rotary dial knob for smooth and accurate hop-up adjustments

• A pre-installed 4mm soft flat nub, optimized for both standard hop and R-Hop setups (6mm optional)

• Compatible with 18.5mm nozzles and most aftermarket soft or hard buckings

• A self-centering inlet design keeps the chamber perfectly aligned with the gearbox nozzle output (11.5mm), eliminating wobble or misfeeds

• Includes a CNC Delrin Locking C-Clip to secure the inner barrel tightly in place – no twisting, no play

Thanks to its premium construction and sealed fit, this chamber can potentially increase FPS by 10–30 FPS compared to stock setups, depending on your build. However, the real strength lies in its reliable hop-up pressure, improved air seal, and consistent flight path.

For added versatility, the chamber also supports an optional Dual UV LED Tracer Module (sold separately), allowing you to light up tracer BBs for CQB or night play.
