"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.

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!

high quality
better compression
works perfectly in cyma cm036

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.)

"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.

"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.

"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
