"This is the only nub you should use for flat hops. Does its job and at a cheap price compared to the competition. Pair this with any flat hopped bucking and an S/R Hop and you're golden.

"Great, flat nub for flat-hop or maple leaf. Dropped it in my Maruzen Type 96 and a purple promy. Works with the action army hop-up chamber.

"Purchased 2 of these to install in my Cyma M14 Socom. One gun is modded as a DMR and the improvement when flat hopping that rifle was amazing. Shot groups dropped sharply and the random right left stringers I was getting vanished. Very satisfied.

The second gun is modded to run just short of 400fps to keep it full auto legal in my area. (DMR can run up to 450) I haven't really played with this setup yet or performed much accuracy testing but the initial impression is good.

In all an excellent purchase that saved me quite a bit of money over competing brands. Ordering a few more to go into my M4s.

"Installed in a G&P M4, increased the range from 80ft to about 200ft. The stock cylinder nub never really worked properly. The flat nub worked beautifully once shaved down although I cut a little too much off the flat piece and rendered it useless trying to tune it in. Will be putting this in all my guns, greater contact, less hop need be applied allowing unhealthy amounts of hop to be applied if desired. Oh and they're cheap.

"Works 900% better than the round chunk of rubber my gun came with, didn't have to file my bucking arm, or play with stinky crazy glue. A nice foray into flat hop for me....

"Thought this nub would be too hard, but when paired with a prommy flat bucking and retro arms hop up, my cm16 srl is shooting very tight at around 180ft (near max range with stock fps of 310) simple install and no cutting required when used with the retro arms hop up.
Happy with this nub and will buy again.

"using in my dmr paired with a prommy purple and a prommy 455 barrel getting 250 ft effective range

"Probably would work great in an aftermarket hop up unit, or with certain stock units, but it was far too thick to work in my KWA without being cut down- which is difficult to do without causing a slight slope that may affect the BB's horizontal trajectory. Otherwise, looked and worked well
