Huntsman Tactical M4 PDW M-Lok AEG (Polymer Body - HMT17-212752-BLUE) with Pre-Installed Wolverine INFERNO Gen 2 Engine, Spartan Board & FCU Battery

Upgrading an ultra-compact M4 PDW platform into a reliable HPA setup can often involve alignment headaches and gearbox wiring hassles. The Huntsman Tactical M4 PDW Blue HPA Rifle removes the technical struggle, coming expert-assembled and powered by the industry-leading Wolverine INFERNO Gen 2 HPA System.

Wolverine INFERNO Gen 2 Engine & Hybrid Technology

At the heart of this compact platform lies the Wolverine INFERNO Gen 2, world-famous for its revolutionary single-solenoid design and independent nozzle movement. By combining the air efficiency of open-bolt mechanics with the feeding reliability and hop-up stability of closed-bolt systems, the INFERNO Gen 2 ensures consistent nozzle seating before every shot. The result is exceptionally tight shot groupings, predictable BB backspin, and maximum air efficiency out of every tank fill.

Compact PDW Ergonomics & Integrated Spartan Control

Designed specifically for fast-paced CQB clearing, the Huntsman Tactical M4 PDW features a high-density, lightweight polymer receiver, a modern M-LOK handguard for mounting tactical accessories, and a compact PDW-style stock. The eye-catching blue finish gives it a unique custom aesthetic, while the integrated Spartan Board FCU allows quick, direct-trigger programming for dwell, burst modes, and rate-of-fire adjustments without needing external control cards or modules.

Tech Installation & Usage Guidance

To set up, connect the included FCU battery to the Spartan Board wiring harness inside the PDW stock or buffer tube assembly. 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.
