About this model

Tournament replacement cap for airsoft HPA regulators. This 3D-printable replacement cap is designed for use on HPA regulators where tournament rules require the regulator adjustment to be secured against unauthorized changes. The cap features four locking holes around the top. These holes allow a tournament tie/seal to be passed through the cap and a corresponding hole on the regulator, preventing the cap from being unscrewed and the regulator setting from being changed without breaking the tournament seal. The design provides a simple, lightweight and inexpensive replacement for a damaged or lost original cap while retaining the functionality required for tournament inspection.
