"This piston head is quite good overall.
The shape is similar to stock ported piston heads, except for this one has 9 ports (as you can see in the picture)! The construction is very solid, quite lightweight, and the double O-ring is very reliable. Creates perfect air seal in my stock cylinder, given that I have a better air nozzle and cylinder head.
I am new to the complete internal upgrade bandwagon, so assembly was a bit difficult, but nothing I had trouble getting after some tries. The ball bearings are a great touch, they really allow the spring to spin. I had to widen the hole in my stock piston to fit the new part, but that's nothing of an obstacle.
Overall it improved compression and reliability greatly.
