Choosing and using your flag

Select your exact calibre from the product options. If you are unsure about the fit, contact RNR Labs before ordering. Always check that the firearm is unloaded before inserting the flag, follow the manufacturer’s instructions and your range rules, and remove the flag before use. A chamber flag is a visual indicator; it does not replace checking that the firearm is unloaded and handling it safely.
