Double Bell M416 AEG (Tan - Long - BY-812S) with Pre-Installed Wolverine INFERNO Gen 2 Engine, Spartan Board & FCU Battery

Combine iconic European assault rifle ergonomics with unstoppable battlefield reliability in the Double Bell M416 Long HPA Rifle (Tan - BY-812S), custom-fitted from the factory with the industry-leading Wolverine INFERNO Gen 2 HPA Engine! Engineered for mid-to-long-range outdoor skirmishes and MILSIM operations, this extended-barrel M416-style airsoft rifle replaces traditional mechanical gearbox wear, motor heating, and battery drain with smooth, ultra-reliable pneumatic power.

Wolverine INFERNO Gen 2 & Spartan Board Integration At the heart of this custom setup is the world-renowned Wolverine INFERNO Gen 2 single-solenoid HPA engine. Utilizing a patented independent nozzle and poppet system, the INFERNO Gen 2 solves open-bolt loading alignment issues, delivering exceptional air seal efficiency, stable FPS consistency, and instant trigger response. The engine is managed by the integrated Spartan Electronics Board, allowing players to easily program dwell settings, fire modes, and burst options directly through simple trigger inputs without needing external programming cards. An included rechargeable lipo FCU battery fits neatly inside the stock buffer tube compartment, ensuring your build is game-ready right away.

Full-Metal Tan Finish & Extended Quad-Rail Architecture Built around a heavy-duty, full-metal receiver set finished in a tactical Flat Dark Earth (Tan) scheme, the BY-812S platform features the signature raised top rail geometry of the 416 platform. The full-length quad-rail handguard provides abundant 20mm Picatinny real estate for mounting magnified optics, PEQ boxes, tactical flashlights, and vertical foregrips. An extended outer barrel enhances long-range presence, while an adjustable crane stock allows comfortable length-of-pull adjustments across heavy body armor. The high-pressure airline routes cleanly through the pistol grip, complete with a quick-disconnect (QD) fitting for seamless tank regulator hookups.

Unmatched Velocity Tuning & Field Dominance By switching from traditional electric power to HPA, you gain total authority over your rifle's performance. Adjust your muzzle velocity (FPS) on the fly via your tank's external regulator and tune your rate of fire via the Spartan Board to adapt instantly to outdoor velocity limits or squad support roles. Elevate your tactical loadout with the lethal combination of long-barrel M416 styling and precision HPA engineering: the Double Bell M416 Long Tan HPA Rifle with Wolverine INFERNO Gen 2!
