If you're new to airsoft, you've probably heard the term hop-up and wondered, “What does an airsoft hop-up do?” In short, it’s a crucial part of your airsoft gun that dramatically improves accuracy and range.
The hop-up is a device inside the barrel of an airsoft gun that applies backspin to the BB as it’s fired. This backspin creates an aerodynamic effect called the Magnus effect, which counteracts gravity and helps the BB travel further and straighter. Without a hop-up, your shots would quickly dip and lose accuracy.
Most airsoft guns, especially electric airsoft guns, CO2 and Green Gas powered airsoft guns, come with an adjustable hop-up. You can fine-tune it based on the weight of your BBs and the distance you’re shooting. For example, heavier BBs need more hop to stay airborne, while lighter BBs need less.
How to adjust your hop-up:
-
Fire a few test shots at a distant target.
-
If the BBs dip too early, increase the hop-up.
-
If they curve upward, decrease it slightly.
-
Repeat until the BBs fly straight and level for the longest distance.
Mastering your hop-up adjustment is one of the easiest ways to instantly boost your airsoft gun’s performance. For better accuracy and range, make sure your hop-up is dialed in correctly before every match.
