Why have Silver when you can have Gold? GoldGas Premium Quality 12gram CO2 Capsules for airguns and airsoft airguns Benefits of Gold capsules over Silver ones: Strength - GoldGas capsules are made from premium quality steel that is formed into the ubiquitous bottle shape by many applications of pressure of 110 tons. Compression - Capsules are then injected with liquid CO2 at extrememly high pressure - 900 PSI Durability - All GoldGas capsules are then zinc coated for excellent corrosion resistance in most atmospheres, in hard fresh waters, and in contact with many natural and synthetic substances. The process also gives them their distinct gold colour. Shot Count - GoldGas developed the award winning Trophy air pistol using their distinctive gold-coloured capsules and achieved a remarkable shot-count of 50+ shots at a legal maximum of 5.5ft/lbs from each capsule.
