Prometheus Air Seal Chamber Hop-Up Packing (Soft Type)
4582109580455
New product
In stock
More info
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. Tested and approved by RedWolf. Best used on guns that shoot below 400fps.

Prometheus
In Greek mythology, Prometheus created man-kind and stole the power of fire from Mount Olympus and gave it to man-kind. The Myth has little to do with this product but it is a cool story Prometheus Airsoft would like to share with you. Prometheus started in 1998 as an online airsoft forum in 2000 Prometheus started selling online and from there on it grew into a quality brand known for its good performance. Prometheus has a wide range of replica internals. They offer internals such as barrels and hop up chambers.
