Wolverine Airsoft Quake MTW + Inferno XTS Upgrade Kit

Experience the QUAKE MTW!

Bring unmatched realism to your build with the QUAKE MTW recoil system, a lightweight, high‑impact upgrade designed specifically for the MTW platform. The patent‑pending Actuated Stock System is purely HPA driven and interfaces directly with the updated INFERNO XTS HPA Engine’s recoil port to power both firing and realistic recoil simultaneously. Instead of relying on added weights, each shot uses the full weapon mass to deliver authentic kick straight to your shoulder, making this module a standout choice for any Airsoft Rifle or HPA Rifle conversion focused on immersion.

Despite producing up to 35 lbs of force, the QUAKE MTW adds just 2.7 oz (76 g) to the platform and requires no extra electronics — ideal for Speedsoft players and those who want a compact, responsive Speedsoft Gun setup. Recoil is tuneable using internal flow reducers, and the system pairs with standard MTW components and an INFERNO XTS HPA Engine (solenoid not included) to form a turnkey HPA Gun upgrade. For operators assembling a complete Airsoft HPA kit, the QUAKE MTW integrates cleanly with airsoft hpa tanks and existing HPA Engine installs.

The package includes the QUAKE MTW Recoil Stock, INFERNO XTS HPA Engine (solenoid not included), hardpoint adapter, mini airline, red FRAC airline for M4, QD sling plate, castle nut, and O‑ring kits — everything needed to add lifelike recoil to your Airsoft Gun. Technical specs show an engine input pressure of 60–160 PSI (80–150 PSI recommended with QUAKE installed), adjustable output energy of 0.75–2 J (build dependent), and an adjustable ROF of 5–35 RPS (5–25 RPS with QUAKE fitted). Typical efficiency at 110 PSI yields approximately 2,000–2,700 shots per 48/3000 HPA tank, with fully adjustable dwell and JST 6–8V battery input for FCU components.

Compatibility covers MTW M4, MTW‑9, and MTW‑308 (MTW‑Shotgun requires an adapter), while Gen‑12 MTW Shotgun, WRAITH products, and Heretic Labs drop stocks/tank grips are not compatible. Whether you’re sourcing parts in HPA UK markets, hunting an hpa engine uk supplier, looking for an airsoft hpa tank, or building a complete airsoft hpa kit, the QUAKE MTW is a compact, effective solution to turn any MTW into a true HPA recoil platform for Airsoft, Speedsoft, and serious HPA Gun enthusiasts.
