Maple Leaf CNC Aluminum Hopup Adjustment Wheel for Elite Force / UMAREX GLOCK, ISSC M22, SAI BLU, Lonewolf, & Compatible Airsoft Gas Blowback Pistols

"Fit my KJW G26 hop chamber without any issues, allows more adjustment and looks cool too. Perfect.

"Works great in my WE G19. It is very easy to spin in the stock hop up chamber. This gives you a more precise adjustment to your hop. Not a necessity just an extra luxury. Not quite worth $10 but good part.

"This does not work for tm mk23 ,they make another one that does work though but this one is a no go for the mk23 nbb guns

"excellent product

It worked very well on the "hopup maple leaf" of my we g35 !!!

improves the spin setting of bb

"Super nice replacement, the Aluminum wheels spin much better in the hop up units as well they allow more customization to your hop which is good if you use heavy bbs .28-.33g (ie. the Plastic Marui one has the path way blocked in the degassing for the hop up arm from poor design from the injection moulding)

"This thing is really cool. It does indeed increase the amount of hop you can give your bb, but I suggest pairing this with a steel hopup arm, and if you have the money, the Maple Leaf I-key thingey. It is great on it's own, but would work alot better with this pair.

My only grip is that it sits so low to the hopup unit that when the unit is put together, it is close to impossible to adjust the hopup with how thin the pegs sticking out of the wheel are. I have to unscrew the hopup in order to adjust it with this in. I think this can be solved after use though.

"Everything about this product is good but have one gripe with it. The groves on the side are way too shallow to get the darn thing to spin when installed (even with fingernails). I cant apply hop-up when I cant move the gosh darn wheel! I don't know if I got a lemon or what so just be aware of this possibility.
