Double Bell M16 SPR MOD2 DMR (Full Metal CNC - 053) with Pre-Installed Wolverine INFERNO Gen 2 Engine, Spartan Board & FCU Battery

Building an ultra-consistent Designated Marksman Rifle (DMR) on a long-barreled SPR platform often requires extensive gearbox shimming, compression tuning, and custom alignment. The Double Bell M16 SPR MOD2 DMR HPA Rifle (053) removes all technical complexity, arriving fully assembled and expert-tuned with the industry-leading Wolverine INFERNO Gen 2 HPA System.

Wolverine INFERNO Gen 2 Engine & Hybrid Technology

At the heart of this precision build lies the Wolverine INFERNO Gen 2, celebrated worldwide for its single-solenoid architecture and independent nozzle movement. By combining the pneumatic 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 tight velocity consistency, laser-flat trajectories over long distances, and maximum air efficiency from every tank fill.

Heavy-Duty Full-Metal Ergonomics & Integrated Spartan Control

The Double Bell 053 platform captures the imposing footprint of the MK12 / SPR MOD2 platform, featuring a full-metal CNC receiver, continuous top Picatinny rail for high-magnification optics, free-float handguard, and a fixed full-length M16 stock capable of housing large battery setups or air routing. Controlled via the integrated Spartan Board FCU, players can easily fine-tune dwell time, rate of fire, and burst/semi-auto settings directly through trigger inputs—eliminating the need for external programming boxes or complicated phone apps. Simply hook up your airline and regulator to dominate the field.

Key Features & Technical Benefits:

• Full-Metal CNC Construction: Precision-machined receiver, heavy outer barrel, and SPR MOD2 rail system for maximum structural rigidity.

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

• Spartan Board FCU Control: Easily adjust dwell, rate of fire, and fire modes directly through 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-driven activation completely removes mechanical gear delay for instantaneous sniper/DMR shots.

• Full-Length Continuous Upper Rail: Ample real estate for scope rings, thermal optics, and tactical accessories.

• Fully Adjustable Output: Easily adjust FPS and rate of fire through your external HPA regulator and FCU parameters.

Tech Installation & Usage Guidance

To set up, connect the included FCU battery to the Spartan Board wiring harness inside the fixed M16 stock. 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.
