"(medium) wonderful product and great control over hop. the hard is often too sensitive and the soft is inaccurate with heavy bbs. I'm using .28s and it does perfect for my application, note: I had to cut off a section of the rubber walls to fit my hop up. expensive but a great product

"Great Nub for flat hop builds. I use a flat hop because it's easy to do and almost as good as R hop methods for low FPS builds. I use it with a prommy purple nub and a lambda barrel and it makes for a great setup.

"Great if paired with a prometheus purple bucking and prowin hope unit.

"Works great with retro arms hopup unit. Nice consistent shots. Definitely overpriced. Not much else to say. 10/10

"I flat hopped my KWA RM4a1 ERG using a promy purple and this nub as it came recommended to do so and with some tweaking here and there mainly because the hop up chamber was so damn tight to anything else other than the original bucking, I got it to work and work it does. I will be honest I did not think that flat hopping would make this much of a difference but WOW! I can now hop .36 gram bbs with ease and even over hop them, I gained some fps and range at least another 30 40 yards with .30 gram bbs.
