Prometheus Air Seal Chamber Hop-Up Packing (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 red version is made from a harder compound and is best used on guns that shoot above 400fps.
- Suitable for virtually all AEGs.
