They're not bad, but they're not good either.
The aluminum cylinder head is nice, however, it only has 1 o-ring to support seal. Nothing a little bit of electrical tape can't fix..
The pistonhead's o-ring is crap, replaced it with my stock o-ring.
It seems like they leak pretty hard, my FPS dropped at least by 20.
However, I do like how it gives a silent compression to it, more of a thud instead of a slap whenever it hits the head.
