BYRNA 12 GRAM CO2 CARTRIDGES 10 Pack

BYRNA 12G CO2 cartridges are specially designed for the BYRNA HD with the BYRNA BOOST 12G adaptor. These cartridges can increase the shot capacity to 30 rounds per cartridge. It's advisable to replace punctured CO2 cartridges and keep an un - punctured one in the Byrna HD to prevent compressed air loss. The Byrna HD punctures and fires the first round simultaneously.

When you're ready to shoot, the Byrna HD will puncture the cartridge and fire the first round at the same time. As a safety and performance measure, always replace the punctured CO2 cartridges with new ones and keep an un - punctured cartridge in the device to avoid air loss. Also, remember that due to shipping restrictions, these cartridges can't be sent to Hawaii and certain cities in New York and California.
