R2 USA 9mm Luger Ammo Chamber Checker Buffer

The R2 USA Pistol Chamber Checker allows you to check that your ammunition is not too tight or too loose to fit in its chamber. It's ideal for reloaders or shooters who want to ensure all their ammunition meets specifications before firing in a crucial match.

This tool helps prevent jams, misfires, misfeeds, and other malfunctions caused by out-of-spec ammunition, which could cost you valuable points or the entire match. Simply insert the loaded rounds into the chamber checker; if the round is flush with the top of the block, it will fit in the gun's chamber.
