JT 90g CO2 Cartridges (15 Pack) – Compatible with 88g Systems for Paintball & Air Rifles

Overview

When Crosman phased out the 88g AirSource line, JT offered a practical alternative: a 90g CO2 cartridge designed to slot into the same systems. This 15-pack provides a reliable gas supply for longer sessions, reducing the need for frequent swaps while delivering consistent performance. The design emphasizes compatibility, convenience, and real‑world usability on the field or in the backyard range.

Reliability and design

These cartridges are built to work with guns that previously used 88g cartridges. They are approximately 0.5 inches longer than the Crosman 88g AirSource cylinders, a size variance to keep in mind when pairing with certain barrels or receivers. The extra gas capacity can translate into steadier shot cadence and fewer interruptions during continuous play.

Key compatibility and fit

• Compatible with any air rifle or paintball gun that accepts 88g cartridges.
• Approximately 0.5 inches longer than Crosman 88g AirSource cylinders.
• Seller has tested in Hammerli 850, Gamo Extreme, and QB79 with excellent results.
• Remember to always apply a drop of airgun oil to the tip of the cylinder and on the threads.

What to expect in practice

In field or range settings, the 90g fill can support longer shooting sessions with a more consistent gas supply across multiple shots. The extra capacity is useful for practice drills, speed runs, or extended games where gas management matters but does not guarantee outcomes.

Use cases and benefits

• Backyard practice with fewer cartridge changes and less downtime.
• Club or tournament practice where dependable gas supply supports steady performance.
• Emergency backup for events requiring reliable CO2 availability.

Care and maintenance

Proper handling helps preserve performance and safety. Store cartridges in a cool, dry place away from direct heat. Before installation, apply a small amount of airgun oil to the tip and to the threads to ensure smooth sealing.

Overall, the JT 90g CO2 cartridge pack offers a practical, ready-to-use solution for users who need compatible gas options without frequent replacements. It blends convenience with real-world usability, presenting a credible option for longer practice sessions or casual play.
