Paintball guns have a canister of compressed gas mounted to them. When the gas supply runs out, youll have to refill it with fresh gas. Fortunately, you can do more than that with this Redline Airsoft Mini-SFR Air System.

Green gas airsoft guns also use compressed gas canisters, and you can buy those in bulk. You can easily refill them and keep on shooting when they run out.

The braided hose and valves are rugged enough to withstand a beating. Remember when servicing your CO2 canisters, using the best equipment will promote longevity and service life.
