Adjustable Hop-Up

A device for giving the bullet backward rotation which straighten ballistic curve and increases the range is called Hop-Up. Weapons with adjustable Hop-Up allow continuous pressure adjusted by the user, so it is very easy and comfortable to achieve optimal Hop-Up effects and using different types of BBs (various weights and manufacturer). If you prefer a higher shooting accuracy for shorter distances, so we recommend using a higher weight BBs. If you require a higher initial muzzle velocity or want to shoot more cheaply, so choose lower weight. It should be understood that a higher initial velocity does not automatically mean a longer range. Weapons with high performance reach a longer range, using heavier of BBs.
