Sig Sauer MPX Sub-Machine Gun (Black) with Pre-Installed Wolverine INFERNO Gen 2 Engine, Spartan Board & FCU Battery

Transforming a licensed Sig Sauer MPX into a high-performance HPA system usually comes with gearbox alignment headaches and custom nozzle fitting challenges. The Sig Sauer MPX HPA Rifle removes all technical friction, 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 licensed submachine gun lies the Wolverine INFERNO Gen 2, celebrated worldwide for its 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 precise nozzle positioning before every shot. The result is exceptionally consistent shot-to-shot velocity, tight groupings, and maximum air efficiency from every tank fill.

Officially Licensed Ergonomics & Integrated Spartan Control

The Sig Sauer MPX features an authentic full-metal/high-grade composite build, authentic markings, an integrated M-LOK handguard for tactical accessories, and a multi-position telescoping stock. Controlled via the integrated Spartan Board FCU, players can easily fine-tune dwell time, rate of fire, and burst modes directly through trigger inputs—eliminating the need for external programming boxes or complicated phone apps. Simply attach your airline and regulator to command the skirmish field.

Tech Installation & Usage Guidance

To set up, connect the included FCU battery to the Spartan Board wiring harness inside the receiver or stock compartment. 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.
