Looking for a gun with extra power and punchy performance, whether it is summer or winter? Then CO2 airsoft guns are the perfect choice. Here you will find a strong range of CO2 pistols and rifles for airsoft. CO2-powered guns are known for delivering a higher muzzle velocity and a stronger kick (recoil) than traditional gas guns, which makes them extremely popular with both tactical players and enthusiasts.
Why choose CO2 over gas?
The biggest advantage of CO2 guns is their stability in changing weather. Whereas ordinary airsoft gas (green gas) often loses pressure when the temperature drops, CO2 is unaffected. That means:
Year-round performance: Your CO2 guns work exactly as they should, even on cold winter days.
Higher impact energy: CO2 generally delivers more pressure, resulting in a harder-shooting pistol or rifle – ideal for long-range shooting or target shooting.
Realistic blowback: Thanks to the higher pressure, you get a more pronounced and realistic recoil on blowback models, which adds to the immersion in the game.
Maintaining your CO2 seals
CO2 is a "dry" gas, which places demands on your maintenance. To ensure a long life and avoid leaks, it is important to lubricate the gun correctly:
Silicone oil is a must: Lubricate the fill valve, the slide and especially the CO2 seals with a good silicone spray or oil after every use.
Remove the capsule: Always remember to remove the CO2 capsule from the magazine or gun after use. If the capsule stays pierced and under pressure for a long time, the seals are crushed flat and start to leak.
We take regulations seriously. We only sell airsoft guns that fire 6 mm BBs (plastic BBs) – we do not sell 4.5 mm CO2 guns that fire pellets or steel BBs. Rules differ from country to country, so check the regulations in your country, so you can enjoy your hobby safely and within the law.

Whether you are looking for an affordable CO2 pistol for the garden or a high-end metal model with full blowback for milsim, we have the right solution. Remember to check your gun with a chronograph, as CO2 often shoots very hard and has to be kept within the site's joule limits.
For your safety, we always recommend wearing approved shooting glasses and masks, and remember to transport your gear discreetly in a gun bag.
