"Very solid piece fits well in my Matrix special edition beta AK
by Dean J. on 01/22/2022
"works well with a G&G green bucking (cold weather version, thats the one I used). solved my double feeding issues in a stock CYMA. excellent upgrade.

also, this DOES come with a basic hop rubber, so keep that in mind while you are shopping

"Good hop up unit for beginning upgrades! Do note though, mine did not work with a G&G green bucking, I needed to use the stock one. Luckily, it comes with a bucking as well as a nub, so you don't have to worry about trying to find other compatible parts (unlike most Matrix products). I would highly recommend this for the cheap price point for those looking for a slight upgrade in range and hop up stability! As a bonus, i didn't have any mag trouble with any of my CYMA mags, which is probably because I was installing it in a CYMA AK that came with a plastic version of this exact same unit.

"Just put this on my gf76 with stock and plastic everything and it out performs my buddy's krytac mk II pdw straight out the box( he just bought it so we had to compare lol)....but I had to do a little adjustment because the unit was a little closer then the original plastic unit and the magazines wouldn't fit but I just moved it back as close to the original as I could and it's perfect

by Douglas D. on 01/13/2016
"Just finished putting this in my CM046 ak. Great accuracy and with a mad bull bucking fixed the issues i was having with compression due to a crack in my original plastic hop up

"Works great in my AMD-65 AK. My original plastic version just broke instantly when removing a few screws. This was an easy/awesome replacement.

cons:
Barrel locking clip is square on the under side. Wouldn't fit. I clipped it on and dremeled it flush. Other than that mod/fix it works great.

"This is a great hop up unit. it works perfectly with my CYMA cm.036 i was upgrading my barrel to a jbu tightbore, and decided to get a new hop up unit and bucking aswell. Everything worked perfectly, it probably increases my air nozzel compression a bit. The only problem i had was that it doesnt work with my CYMA magazines so i just ordered a tokyo marui exact replica mag for it and it works fine!

Pros:
Metal
high quality
better compression
works perfectly in cyma cm036

Cons:
Doesnt work with cyma mags (its because the tab that needs to be pushed down but the edge of the hop up unit is rounded on CYMA mags, so the hop up unit gets caught on it.)
by John C. on 03/21/2009
"Works great in my DBOY AK-74M(RK-05). The opening for the BBs is a little bigger than the stock hop-up so the stock magazine had to modified. The BB catch in the magazine feed had to be trimmed down a bit to allow the magazine secure itself into the magwell.
by Arthur K. on 08/22/2008
"Works flawlessly in my CYMA AK47. It is made out of metal so it does not crack easily like the plastic hopup units. Very good air seal.
by THE TL D. on 10/29/2008
"This hop up is great! It is very tight fit for barrels. The only problem with this hop up is that because it is metal it creates alot of nosie . Be warned
