Matrix CNC Aluminum Airsoft AEG Gearbox Piston Head

"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.

"Nice solid piston head, bought it for durability mainly, in conjunction with a few other Matrix goodies.
Build quality is spot on, and I would recommend it highly to anyone.

"Absolutely fantastic. A bit overpriced in my opinion, but so worth it. The piston head has 8 ports, is metal, and the o-ring is very loose and thick (which is great for air seal). I installed this in my brothers G&P Tank and it had perfect, absolutely PERFECT air seal with all the other STOCK G&P air seal parts. If you want an awesome piston head that is very durable and this.

"It's a good piston head that matches great with a USB light weight full Metal tooth piston. The only problem was the oring that came with it was too small and did not create an air seal at all. It is a black oring instead of the green one as shown,I'm bring generous for giving it a 4 star and not a 3 star. All in all a great piston head with a great build quality.

"This was a good piston but within two matches I found out one side got bent out of place.
