Maxx Model CNC Aluminum Double O-Ring High Performance Ball Bearing AEG Piston Head

"Best piston head on the market! Beautifully machined, perfect air seal and even has a small, second o-ring to prevent piston to cylinder contact.

"I have this in a pretty mild build shooting 396+/- .5 fps with .20 bbs at 26rps. It greatly improved my consistency over the stock krytac piston head, i was shooting /-5, super happy with this thing

"Paired it with a Lonex ported cylinder and it is tight to the point that a bit too much silicon oil was needed to make the piston move more freely.

The quality is excellent, just like any other Maxx product.

The best part about this piston head matched with a Maxx cylinder 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.
