CYMA Standard M4 8.5 M-LOK AEG (Tracer Hop-Up - Black - CM.068M-8.5) with Pre-Installed Wolverine INFERNO Gen 2 Engine, Spartan Board & FCU Battery

Integrating an internal tracer hop-up unit alongside an HPA engine modification often requires intricate wiring, soldering, and custom component fitting. The CYMA Standard M4 8.5 M-LOK Tracer HPA Rifle eliminates all technical complexity, arriving fully assembled and expert-tuned with the industry-leading Wolverine INFERNO Gen 2 HPA System.

Wolverine INFERNO Gen 2 Engine & Hybrid Technology

At the core of this custom build is the Wolverine INFERNO Gen 2, celebrated globally for its single-solenoid design and independent nozzle movement. By combining the pneumatic air efficiency of open-bolt mechanics with the feeding reliability and hop-up seating precision of closed-bolt systems, the INFERNO Gen 2 eliminates misfeeds and nozzle misalignment. The result is exceptionally consistent shot-to-shot velocity, tight groupings, and maximum air efficiency from every tank fill.

Integrated Hop-Up Tracer System & Spartan Control

The stand-out feature of the CM.068M-8.5 is its integrated Tracer Hop-Up Chamber, which activates internal LEDs directly inside the feed path. Every tracer BB is charged instantly upon entering the chamber, eliminating the need for bulky front muzzle tracer units and maintaining a slick, maneuverable 8.5-inch barrel profile. Controlled via the integrated Spartan Board FCU, players can easily fine-tune dwell time, rate of fire, and burst modes directly through trigger inputs without external programming tools.

Key Features & Technical Benefits:

• Built-In Hop-Up Tracer Unit: Internal illumination charges tracer BBs inside the hop chamber without external front-end attachments.

• Pre-Installed Wolverine INFERNO Gen 2: Premium single-solenoid HPA engine offering superior air efficiency and precision nozzle seating.

• Spartan Board FCU Control: Easily adjust dwell, rate of fire, and burst modes directly through trigger inputs.

• Included FCU Battery: Comes supplied with a dedicated LiPo FCU battery to power internal electronics and tracer LEDs out of the box.

• Instant Trigger Response: Solenoid-driven activation completely removes mechanical gear delay for instantaneous shots.

• Modular 8.5" M-LOK Handguard: Compact footprint designed for fast room clearing, tight corners, and tactical accessory mounting.

• Fully Adjustable Output: Easily adjust FPS and rate of fire through your external HPA regulator and FCU parameters.

Tech Installation & Usage Guidance

To set up, connect the included FCU battery to the Spartan Board and tracer wiring harness inside the stock compartment or buffer tube. Connect your high-pressure air line (standard QD fitting) to the lower grip line. Set your external regulator within the engine's recommended operating pressure range (typically 60–120 PSI) prior to firing. Always disconnect the FCU battery when storing the rifle to prevent deep battery discharge and battery draining from the tracer board.
