The Pro-Shot UV Bore Light Chamber Flag (Pro-Shot part no. BL2CFGREEN) is a fast, no-battery way to check a barrel for fouling or wear. Insert the short end into the chamber and the neon green fiber optic tool lights up the bore for a clear visual inspection, whether you’re checking a rifle or pistol before storage or after a cleaning session. It’s rated for .22 caliber and up, making it suitable for most centerfire pistols and rifles, including 9mm. Because it relies on fiber optic light transfer rather than a battery or bulb, it’s always ready to use at home or in the field, and the pack includes two flags so you always have a spare on hand.
