Redefine the purpose of a cartridge with our 7.62 Keychain Bottle Opener. Not only is this military-grade, once fired brass a nifty decoration on your keychain, it will open your favorite bottled beverages too! The 7.62mm cartridge features a precise semi-oval cut near the extracting groove that serves as the bottle opener. We’ve etched the NRA letters on this hand pressed piece. Not recommended for carry during air travel. 100% made in USA.
