Construction & Reliability

The MCX Virtus PROFORCE platform combines a rigid metal upper receiver with reinforced polymer components to maintain strength while keeping handling balanced. Internally, the Wolverine Inferno 2 replaces the traditional gearbox with a sealed electro-pneumatic HPA system, removing gears, pistons and springs that are prone to wear or failure.

This results in a cleaner-running, lower-maintenance system capable of handling high rates of fire and extended skirmish days with minimal performance drop-off.

Performance & Field Use

Powered by high-pressure air, the Inferno 2 delivers instant trigger response, exceptional consistency and highly efficient air usage. Shot-to-shot deviation is dramatically reduced compared to AEG platforms, making the rifle ideal for players who prioritise accuracy, control and repeatability.

The adjustable hop-up allows precise tuning for BB weight and site limits, while full-auto operation remains smooth and controllable. Semi-auto fire is crisp and predictable, making the platform equally suited to competitive CQB, speedsoft and aggressive outdoor play.
