Prometheus Airsoft Prometheus Hop Up Rubber - Hard Type

If your hop-up adjustment is not having a big effect on the hop-up of your BBs, then it probably means that your hop-up packing is worn down and is not gripping the BB properly before it is fired out. A new hop-up packing will allow more accurate hop-up adjustments. This hard type packing is designed to match high power upgrades at +120m/s. High power upgrades require a harder hop-up packing since softer material may deform from the higher power. However if your gun shoots below 120m/s, then stay with the soft type packing since otherwise this hard type will not grip the BB properly on low power configurations. Especially recommend to use this hard type hop-up packing onto upgraded sniper rilfe as well for improving semi mode shooting effectively.
