Simply put, this hop bucking/rubber is legendary in Airsoft. Much like the fabled Tokyo Marui Magic hop rubbers, these Prometheus Purple hop rubbers are made from some secret combination of elements that allows them to grip BBs strongly without impeding them, giving excellent and consistent hop-effect!
Essentially, if it's range you're after in a standard AEG, this could well be the upgrade you're after!
This hop rubber should be compatible with any standard AEG barrel and hop, but modifications may be required in some cases.
