CNC Aluminum Airsoft AEG Cylinder Head w/ Double O-ring by Matrix (Ver.3 AK)

"Great seal from the double o-rings, but I had to flare out the nozzle a teeny bit to reduce wobble I was getting to the air nozzle. This isn't a fault of the quality though, just hard to match nozzle IDs to cylinder head nozzle ODs.

"This is a great cylinder head especially if you want great compression. I put this along with a new cylinder and piston head and got near to perfect compression. Not much to say, this is just a great cylinder head if you have a ver.3 gearbox buy it!!

"Seems to be a very nice quality cylinder head, but I had to mess with it quite a bit so it would fit in my CYMA AK cylinder. The two o-rings initially prevented this from properly going into the cylinder, so I had to trim them down a lot with some sandpaper so they would fit. Now that this does finally fit, it provides an excellent air seal, is a much tighter fit than the original cylinder head, and looks a lot cooler than it as well lol. Idk why it was at first too big to fit in the cylinder, it's possible that this might be intended for bore up cylinders, idk.. Overall, I don't think this is worth getting as it won't do any crazy upgrade for your gun (I was hoping it'd make my gun a bit quieter but it doesn't really make much of a difference, better shimming=quieter gun) and was for me at least rather hard to install, but if you want that extra bit of air seal and coolness for your Aeg, then go for it. Just keep in mind that it may need some modification to fit.
