Hop-up is the back-spin put on the gel balls to increase their range via the Magnus effect. A Hop-up puts backspin on the gel balls reducing the air pressure on its top side.
THIS Hopup works amazing.
Tested to work well with spring upgrades of 1.2mm/1.3mm/1.4mm (up to 350fps)
I can't stress enough how much of a difference this thing makes.
# Increase distance and accuracy A LOT!
# Forces the balls to back spin.
# Eliminates bullet arc.
☠These give such a great advantage it's literally unfair for anyone else without one☠
