The Bug-A-Salt SHRED-ER CO2 cartridges are a 5-count pack of standard 12-gram, small-neck carbon dioxide cartridges designed specifically for use with the SHRED-ER platform. Each cartridge provides a secure fit and tight seal to ensure consistent pressure and reliable performance during use. These cartridges power the system by delivering compressed CO2, allowing repeated firing without manual pumping and supporting steady shot output. Each cartridge can produce multiple high-powered shots when properly installed. They are manufactured for compatibility with the SHRED-ER model only and are not intended for use with other Bug-A-Salt versions.
