Experience the QUAKE MTW!
Infuse lifelike realism into your gameplay with the QUAKE MTW, the lightweight, durable recoil system specifically crafted for the MTW platform. The patent-pending, Actuated Stock System is purely HPA driven, integrating directly with the novel recoil port of the updated INFERNO XTS HPA engine to simultaneously power firing and recoil. Each shot breathes life into your the MTW, using the full weapon mass to generate authentic kick directly to your shoulder without the need for added weights. The QUAKE MTW is the ultimate upgrade for any MTW!
