In my previous post I said I will explain what hop-up is and how it works.
Hop-up on a airsoft gun is a small system that increases the distance by adding spin onto the plastic BB so by having a high Hop-up the bullet will fly very high.
When you have a low hop-up the bullet wont travel very far and will travel downwards.
So the ideal way to have your hop-up set would be a straight to slightly high and then down. The way you set your hop-up will be different on most guns but they are follow the same laws.
The way the BB should travel is as above. Having the BB travel straight and slightly up and then back down is the perfect hop-up.
Please let me know what you thought of this post and do not forget to have a nice day.
