Hop-up buckings for spring operated guns
An important factor may be the shape or size of the hop-up adjustment and the material of the hop-up adjustment roller. All this has a big impact on performence, stability, performance, hop-up effect, range, etc. This "consumer" part is normally pushed onto inner barrel in the Hop-up chamber. Bad choice hop-up bucking or improper installation can lose more than 10 m/ s. Hop-up bucking is advisable to regularly change, the best always after every season. Its material wears, ages and it loses its properties. In the event that changes the inner barrel, it's usually good or needs to be replaced even hop-up bucking.
