This hop up nub is a plastic spacer that fits the older, non-current version of the AKG Series hop up setup. If your rifle has an upgraded grey bucking and a plastic hop up nub/spacer part 75, then you do not need this part. It is only used with the older hop up assembly that uses a brass nub/spacer part 75.
