High-Capacity CO2 for Rifles
The ASG 88g CO2 Capsule is a large-volume gas cartridge for CO2-powered rifles and carbines. Holding roughly seven times the gas of a standard 12g capsule, it lets you fire many more shots between changes, so it is ideal for extended range sessions and plinking with compatible platforms.
Fit and Compatibility
The capsule has a threaded M16 x 1.5 neck and is designed for guns that accept an 88g cartridge, such as the Sig Sauer MPX and MCX and the ASG TAC Repeat. It measures around 176mm long by 35mm in diameter. It is far too large to fit inside standard airsoft pistols, so always check your gun takes an 88g cartridge before buying.
Consistent Performance
ASG’s Ultrair CO2 is known for a consistent, high fill and a burr-free thread that protects your gun’s seals. Filling pressure is around 60 bar (roughly 900 psi). Explore more gas and propellants in our BBs, gas and batteries range.
Safety and Compliance
CO2 capsules are pressurised, so store them away from heat and never puncture or incinerate them. Sold as a single capsule. This item is strictly for buyers aged 18 or over and needs no UKARA.
