The MDT Chamber Flag Green 10 Pack is a simple, purpose-built safety accessory designed to make it obvious when a firearm’s chamber is empty. Each bright green flag is sized for .22 caliber and larger firearms, with a flexible shaft that inserts into the chamber while the flat tab remains clearly visible above the ejection port.

These flags are ideal for range use, training days, and match environments where clear visual confirmation of an open, empty chamber is required. The vivid green color stands out against dark rifles and shaded bays, helping shooters and range staff verify status at a glance. With ten flags included, you can equip multiple firearms and keep extras in your range bag or club box, backed by MDT’s reputation for thoughtful, shooter-focused design.
