AGM/S&T MK44 AEG (Metal and Wood - Black - AGM/S&T-056B) with Pre-Installed Wolverine INFERNO Gen 2 Engine, Spartan Board & FCU Battery

Converting a classic WWII platform like the StG44 into a high-performance HPA system can be a complex technical project involving custom nozzle alignment and wiring adaptations. The AGM/S&T MK44 (AGM-056B) HPA Rifle delivers a completely turn-key, expert-assembled platform powered by the industry-leading Wolverine INFERNO Gen 2 HPA System.

Wolverine INFERNO Gen 2 Engine & Hybrid Technology

At the core of this historic build is the Wolverine INFERNO Gen 2 engine, famous for its single-solenoid system and independent nozzle movement. By pairing the air efficiency of open-bolt mechanics with the feeding reliability and hop-up stability of closed-bolt designs, the INFERNO Gen 2 eliminates feeding issues and misaligned loading. The result is exceptionally consistent shot-to-shot velocity, tight shot groupings, and impressive air efficiency out of every tank fill.

Authentic Real Wood Construction & Integrated Spartan Control

The AGM/S&T-056B features a 1:1 scale heavy-duty full metal body paired with an authentic real-wood stock, providing remarkable weight and historical realism. Controlled via the integrated Spartan Board FCU, players can fine-tune dwell time, rate of fire, and burst modes directly through trigger pulls, eliminating the need for bulky external programming cards or exposed control modules. Simply attach your air line and tank regulator to bring vintage history into the modern HPA arena.

Key Features & Technical Benefits:

• Authentic StG44/MP44 Replica: Full metal body and genuine real-wood stock for total historical realism.

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

• Spartan Board FCU Control: Easily tune dwell settings, rate-of-fire, and burst modes using direct-trigger inputs.

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

• Instant Trigger Response: Solenoid activation removes mechanical gear delay for instantaneous firing.

• Adjustable Muzzle Velocity: Fine-tune FPS limits using your external air regulator and FCU parameters.

Tech Installation & Usage Guidance

To set up, connect the included FCU battery to the Spartan Board wiring harness inside the wooden 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 pressure range (typically 60–120 PSI) prior to firing. Always disconnect the FCU battery when storing the rifle to prevent deep battery discharge.
