Prometheus Air Seal Hop-Up Hard Type

The Prometheus Air Seal Hop-Up Hard Type is one of the better buckings available, as Prometheus stands for quality.

This bucking is a hard bucking which is particularly suitable for replicas that shoot above 1.2J, such as a DMR. Of course, you can use a softer bucking as well, but due to the high power the bb takes with it, a soft bucking can deform faster and/or break, making your replica inconsistent.
