Airsoft hop up system

The hop up system in an airsoft gun barrel puts a backspin on the pellets to increase their vertical accuracy and distances. This principle causes pressure forcing the airsoft pellets to travel in opposite direction of gravity, which makes the pellets to fall less and gain more range. On most airsoft guns, the hop up can be adjusted because heavier pellets require more of a backspin to contradict gravity. When a hop up is adjusted correctly, it will shoot straighter. This improves the distance and precision drastically. A number of cheap airsoft guns’ hop ups aren’t adjustable causing less accuracy, range, and fewer choices of pellet weights.

Using a new hop up

When a hop up is first installed in an airsoft gun, it won’t be stable and improvements will be minimal until after around 100 pellets are shot. This is caused by the lube from the piston circulated through out the system. Once the lube is reduced, the improvements will appear. Wait on adjusting a hop up until the lube has had a chance to naturally remove from the system.

Avoid any oil to transmit onto the pellets or hop up system. The oil reduces the resistance on the pellets reducing the spin.

Adjustable Vs. Build-in hop up system

These two different systems have their own advantages and disadvantages. The adjustable system allows the players to physically control the hop up range from an opening into the gears. This system is less recommended to new players because the hop up tuners are extremely sensitive and the slight over torque can cause harm. The Build-in system is closed off preventing any tampering preventing any damage that could be caused by an inexperience player. The disadvantage is not allowing the player to adjust the hop up for a personal setting. Both have their different options so it’s mainly based on the player’s preference.

Before purchasing an airsoft gun be aware of the different types of hop up systems and choose one that covers your needs. Got an airsoft gun? Is it an adjustable or build-in hop up system? Go Check!
