First Strike FSC XP, FSC, T8.1 Rear Remote Air Adapter Kit 3.0 oz

The First Strike FSC XP / T8.1 Rear Remote Air Adapter Kit allows you to convert your FSC or T8.1 pistol to run air directly through the rear of the marker, eliminating the need for disposable 8g or 12g CO₂ cartridges.

Designed for First Strike FSC and FSC XP pistols, this adapter enables connection to a remote air line or external HPA source, giving you extended shot count, consistent pressure, and reduced operating cost. Once installed, your pistol draws air from a larger tank carried remotely, making it ideal for magfed play, scenario games, and training environments where reliability and consistency matter.

This kit is only compatible with pistols bearing serial numbers 2000 and higher. To verify compatibility, remove the barrel and inspect the inside of the marker body to locate the serial number before installation.

Purpose-built by First Strike, this rear air conversion is a proven upgrade for players who want to move beyond CO₂ cartridges without sacrificing the compact handling of the FSC platform.
