Maxx CNC Evo-3 Aluminum Hopup Chamber

The Maxx CNC Evo-3 Aluminum Hopup Chamber is a precision-machined upgrade designed for ASG 2018 CZ Scorpion EVO-3 airsoft rifles. It delivers repeatable hop-up control and enhanced consistency for players who demand reliable accuracy in every shot.

• Premium CNC Aluminum Construction: Machined from a solid aircraft-grade aluminum block with tight tolerances for superior accuracy, durability, and repeatable performance.
• Compatibility and Fit: Specifically designed to fit ASG 2018 CZ Scorpion EVO-3 gearboxes with an 11.5mm inlet and 12mm hub diameter, while remaining compatible with a wide range of aftermarket buckings.
• Integrated Precision Rotary Dial Knob: Built-in aluminum dial for precise, repeatable hop-up adjustments without tools.
• Pre-Installed Bucking Nub: Includes a pre-installed 4mm flat soft nub (6mm nub option available) optimized for R-Hop and standard-hop to maximize consistency on every shot.
• Self-Centring Inlet: Ensures the hop-up unit sits perfectly in the 11.5mm inner bore, reducing wobble and misalignment during use.
• Delrin Locking C-Clip: Provides a secure, wobble-free hold on the inner barrel for reliable performance over time.
• 18.5mm Nozzle Length Support: Specifically engineered to accept the 18.5mm nozzle length while maintaining FPS stability with most buckings.
• Optional Dual UV LED Tracer Module: Ready for low-light tracing with an optional UV LED module to glow BBs in the dark (sold separately).
• Comprehensive Included Kit: Everything you need is included—from the EVO chamber and bucking nubs to springs, spacers, O-rings, and the locking hardware.

The Dual UV LED Tracer Module is an add-on option to glow BBs in the dark. It supports operating voltage from 7V to 15V (2–4 cells LiPo, 6–13 cells NiCad) and is sold separately. Test results indicate a potential FPS increase of 10–30 FPS over the stock setup, depending on your configuration and airsoft rifle. This Evo-3 chamber is built to deliver consistent performance across a variety of buckings and setups, making it a solid choice for players who value accuracy and reliability in both CQB and field environments.
