Chamber Empty Flag – with Fabric Indicator

This chamber empty indicator is designed to clearly show that your boomstick's chamber is empty, improving safety during transport, at the range, or in storage. Many shooting ranges now require a visible chamber flag as part of their safety protocols — this unit provides a reliable and professional solution.

The chamber insert is 3D printed in durable ASA material, offering excellent UV and heat resistance, making it suitable for both indoor and outdoor use. Attached to the insert is a highly visible red fabric flag marked with “Chamber Empty” for easy identification from a distance.

• 3D Printed from ASA – UV and heat resistant for long-lasting performance.

• Attached Fabric Flag – Clearly marked with “Chamber Empty” for maximum visibility.
