This is my second Maxx model product and both times I’ve been blown away with the quality and performance. The air seal is better than any other upgrade piston head I have used in a wide variety of guns and this tops all of them. I bought this for my 1918a2 Bar and the air seal is simply outstanding! This thing fits in perfectly and slides super, super smooth and evenly, even without compression. There is absolutely no air loss with this piston head. The fps is super consistent too now, literally /- 2 with a Lonex cylinder head and stock cnc o-ring nozzle.

I will be replacing my other upgraded piston heads with these. Easy 10/10. Throw away your current piston heads and buy it.

"Awesome piston head. I left the O-ring on the outside of a cylinder to stretch it over night and was able to achieve a perfect seal.

"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.
