Increased muzzle velocity gives you more accuracy
Most normal gases are lubricated. This wets the hop-up and you need to apply more pressure which in turn slows the BB. The slowing of the BB and the reduced hop-up leads to less accuracy and poor performance.
Using Abbey Brut Sniper Gas does not wet the hop-up. Its dry formulation keeps the hop-up in perfect condition for rapid fire on full auto. Its blend of carefully selected gases produces maximum power for perfect shooting.
When using Abbey Brut Sniper Gas you can reduce the pressure of the hop-up to increase muzzle velocity. But you still produce maximum backspin. Greater backspin gives a flatter trajectory. A flatter trajectory produces greater accuracy and more enemy kills.
