Power your airsoft guns, air guns, paintball markers, and other CO2-powered equipment with confidence using the 12 Gram CO2 Cartridge Case (500 count) by EMG. Precision-manufactured to the ASTM F590 standard for consumer safety and projectile compatibility, these premium cartridges are engineered for performance, safety, and reliability. Whether you're a competitive airsoft player, a tactical trainer, or a range enthusiast, these cartridges offer consistent pressure and flawless compatibility with a wide range of 12g CO2 platforms.

Manufactured in Taiwan or the USA using world-leading production equipment, these cartridges represent the highest level of quality control in the industry—far exceeding the safety and sizing tolerances of cheap imports. Trusted by professionals and serious hobbyists alike, this bulk case is the perfect choice for airsoft fields, training facilities, and frequent shooters.

Premium Precision for Reliable Performance

Each 12g CO2 cartridge in this 500-count bulk case is made to strict tolerances with a maximum diameter of 18.90mm, ensuring optimal compatibility with most CO2-powered airguns and airsoft replicas. Unlike some low-grade CO2 options, which may suffer from inconsistent sizing or internal flaws, these cartridges are tested to the ASTM F590 standard, which guarantees precise fit and reliable function.

Use them with complete peace of mind in EMG, KWC, APS, Crosman, Glock, and other professional-grade training and recreational airsoft systems. They’re also compatible with paintball pistols, CO2-powered grenades, and any device requiring a standard 12g CO2 canister.

Tested for Safety and Strength

Every cartridge is pressure-tested between 7200–7800 PSI, making these some of the safest and most reliable 12g CO2 cartridges on the market. In fact, each production batch is individually tested for burst safety and thermal resistance, ensuring durability under real-world conditions.

To avoid jams, malfunctions, or dangerous overpressure, precision matters. These cartridges avoid the defects and inconsistencies common in "Made in China" CO2 canisters, which may have microfractures, unclean seals, or slight diameter variations that can cause damage or unreliable firing.

Designed for All 12g CO2 Applications

Whether you’re powering an airsoft pistol, a semi-auto airgun, or a paintball sidearm, these cartridges deliver clean, consistent gas output. With high internal pressure and precision threading, they maintain stable power output across multiple shots, improving both FPS consistency and cycle reliability. They're ideal for:

• Law enforcement and military training replicas

• Competitive airsoft pistols and carbines

• Paintball markers and launchers

• CO2-powered grenades, traps, and tools
