Maxx Model CNC Aluminum Double O-Ring AEG Cylinder Head

"Beautiful part with perfect air seal. Works great and looks just as good, just be careful of the sharp edges! Only criticisms would be that it could use a thicker rubber pad and rounded off edges- to reduce finger punctures.
Not the most quiet cylinder head, but should last forever.

"Fits well, excellent airseal. Do not use this in a DSG or high stress build, you want a polymer cylinder head for that. No problems with the product itself for its intended usage, so 5/5 stars.

"This in a Lonex cylinder fits like a glove. It's real tight with perfect airseal.

The quality is excellent, just like any other Maxx product, but the rubber pad started to come off. It's nothing major, I just need to push it into place every time I take the cylinder off the gearbox.

The best part about this cylinder head matched with a Maxx piston head and nozzle is the sound it makes. Not only the airseal is perfect but it makes a loud satisfying THUMP that makes a foam filled suppressor actually silence an AEG.

If you like a loud piston noise or you just want perfect airseal, this is for you.
