Prometheus Air Seal Chamber Hop-Up Packing for AEG (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 400fps+. High power upgrades require a harder hop-up packing since softer material may deform from the higher power. Tested and approved by RedWolf. Especially recommend to use this hard type hop-up packing onto upgraded sniper rilfe as well for improving semi mode shooting effectively.
