Sig Sauer MCX Virtus ProForce (Black) with Pre-Installed Wolverine INFERNO Gen 2 Engine, Spartan Board & FCU Battery

Converting a licensed Sig Sauer MCX Virtus into a high-performance HPA system can often present gearbox alignment hurdles, tight wiring routing, and custom nozzle fitting challenges. The Sig Sauer MCX Virtus ProForce Black HPA Rifle eliminates 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 core of this licensed build lies the Wolverine INFERNO Gen 2, world-renowned for its single-solenoid architecture and independent nozzle movement. By combining the air efficiency of open-bolt mechanics with the feeding accuracy and hop-up seating 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 MCX Virtus features an authentic full-metal receiver set, an integrated M-LOK handguard for mounting lights, grips, and lasers, and a multi-position telescoping PDW/carbine 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 connect your airline and regulator to command the field.

Tech Installation & Usage Guidance

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