First Strike FS Roscoe Constant Air Adaptor

Experience seamless, high-performance play with the First Strike FS Roscoe Constant Air Adapter, engineered to take your .50 caliber revolver action to the next level. Designed specifically for the FS Roscoe revolver, this adapter lets you link your marker to a remote air source, so you never have to fumble with 12-gram CO₂ cartridges again. Imagine uninterrupted action, consistent shot power, and the freedom to focus on strategy instead of swapping gas canisters.

With the FS Constant Air Adapter, you tap into a reliable air supply—whether a high-pressure HPA tank or on-board cylinder. The result? Steady 280 feet-per-second velocity that stays rock solid, shot after shot, even when the competition heats up. At only a few ounces, this lightweight adapter adds minimal bulk, preserving the balanced feel of your FS Roscoe revolver in your hand. Its precision-machined aluminum body stands up to the toughest woodsball environments, resisting dents and corrosion while maintaining a sleek, tactical profile.

Installation is lightning-fast. Thread the adapter onto the bottom of your Roscoe’s grip frame, attach your macroline hose, and you’re ready to roll. No tools required. The robust O-ring seals ensure zero leaks, even under high pressure, giving you the confidence to push your marker to its limits. Backed by First Strike’s reputation for milsim-grade engineering, you’ll enjoy years of reliable service and the flexibility to customize your setup with other tactical accessories—rails, grips, lights and lasers—all designed to enhance your realism and accuracy.

Whether you’re storming the objective in a woodsball scenario or training with precision drills on the range, the FS Roscoe Constant Air Adapter is the ultimate upgrade for players who demand consistency, durability, and ease of use. Say goodbye to mid-game reloads of CO₂ cartridges and hello to uninterrupted performance that keeps you locked, loaded, and in the fight.
