"Great kit, although I bought two and neither of them came with the mushroom piston head as shown. Also, one of the piston heads cracked and broke after a few shots on a stock spring. The cylinder is a nice upgrade though despite the cheap piston heads that actually come with this kit..

The Angel Custom "Seraph Angel" High Performance Polycarbonate Piston Head is the piston head that actually comes with this kit

"Fabulous cylinder, to put it simply. Looks beastly in my M4 DMR build and even better in contrast with the blue hop up unit. The bearing works great and so does the piston. Just be sure to tighten the screw with some Locktite.

"The kit itself is really nice. Its fitting is perfect, in respect to my G&G gr16. The only issue I'm having is the Piston heads O-ring is to small. The ring bleads air through because of this and it will constantly loose and gain pressure repeatedly. So in short my shots very from 360fps to 435fps, but that is the only issue I just have go get a new o-ring or see if somehow I can get this one to stretch out some.
Great product, still would recommend if you do not know what pieces you'll need to tune your cylinder.
