Building a custom high-performance HPA setup often requires technical expertise, precision alignment, and extensive tuning. The Double Eagle M924 DMP-9 SMG (Black) bypasses the workbench by offering a fully assembled, turn-key HPA platform powered by the Wolverine INFERNO Gen 2 HPA Engine and controlled via the streamlined Spartan Board.

Wolverine INFERNO Gen 2 Engine & Hybrid Technology

At the heart of this SMG lies the Wolverine INFERNO Gen 2, renowned for its revolutionary single-solenoid design and independent nozzle movement. By combining the efficiency of a single solenoid with the precise air sealing of a closed-bolt system, the INFERNO Gen 2 virtually eliminates open-bolt feeding issues and loading nozzle misalignment. This results in razor-sharp hop-up engagement, consistent shot groupings, and impressive air efficiency across various FPS limits and dwell settings.

Compact DMP-9 Platform & Integrated Spartan Board

The Double Eagle DMP-9 platform is built for fast-paced CQB clearing and rapid maneuvering. Featuring a durable high-grade polymer receiver, M-LOK handguard, ergonomic pistol grip, and a quick-deploy PDW stock, it keeps total weight minimal without sacrificing structural integrity. Integrated directly into the trigger assembly, the Spartan Board FCU allows quick, dwell-and-fire-mode programming directly via trigger pulls, removing the need for bulky external wire harnesses or complicated programming units.

Key Features & Technical Benefits:

  • Pre-Installed Wolverine INFERNO Gen 2: Premium single-solenoid HPA engine offering supreme consistency and air efficiency.

  • Spartan Board Control: Direct-trigger programmable FCU for dwell, burst modes, and rate-of-fire adjustments without external modules.

  • Included FCU Battery: Comes supplied with a lipo FCU battery to power the internal solenoid board immediately out of the box.

  • CQB-Optimized Build: Lightweight polymer receiver paired with an M-LOK handguard and multi-position PDW stock for maximum agility.

  • Instant Trigger Response: Solenoid activation removes mechanical gear lag for instant, crisp shot cycles on semi-auto.

  • Fully Adjustable Output: Easily adjust FPS and rate of fire (ROF) through your external HPA regulator and FCU settings.

Tech Installation & Usage Guidance

To operate, connect the included FCU battery to the Spartan Board wire harness located inside the grip or stock housing. Plug your standard HPA airline (QD connection) into the engine's lower grip line. Ensure your external regulator is set to the manufacturer's recommended operating pressure range (typically 60–120 PSI) before firing. Always disconnect the FCU battery when the rifle is not in use to prevent deep discharge.

Faulty Product?! Unfortunately that is part of life but be rest assured we are here to help! Contact one of our friendly staff via phone or email. Stating what the problem is, if we can resolve the problem via phone or email great if not then they will advise how to send it back and what details we require.

Two tone
We can two tone any weapon we sell at Bespoke Airsoft. The purpose for two toning is if you do not hold a valid defense under the Violent Crimes Reduction Act (VCRA, 2006) which is to prevent the misuse of Replica Weapons, which applies in England, Scotland, Wales and Northern Ireland.

The gun will be sprayed 51% in a bright/primary color (we do only blue, green and red currently). The process of two toning currently runs at 2 working days depending on Drying Time, which is effected by Ambient Temperature and Weather. and currently no express delivery is available for this even if you select it at checkout.
