ABBEY BRUT SNIPER GAS 700ML

Most normal gases are lubricated which wets the hop-up. This means you need to apply more pressure which, in turn, slows the BBs. Slower BBs and reduced hop-up lead to less accuracy and poor performance.
When using Brut Sniper Gas, you can reduce the pressure of the hop-up to increase muzzle velocity and still produce maximum backspin. Greater backspin gives a flatter trajectory which leads to higher accuracy and more kills.
