"i have been skeptical of ICS parts and guns since my 1st M4 was an ICS and the piston stripped 3 times in the month i had it, but this piston is probably the absolute best piston i have ever used. the compression in my Angels Custom cylinder and matrix cylinder head is perfect. i have never seen this great of compression and durability outside of a one piece cylinder and head. it also improved my trigger response by A LOT. its in my Beta Project AK and i finally made the trigger short and responsive and i love it! i plan on putting one in a couple more of my guns!

"Excellent combo right hear. Incredibly durable and crazy good compression. I recommend this to anyone who wants to save money and time.

"Bought this for my CM16, has great compression on the stock cylinder and may need some AOE(angle of engagement) correction. The ball bearing are fluid when combined with a ball bearing spring guide. I dont see this thing breaking, probably the heaviest duty polycarb piston/head.

"I bought this for an MP5 and was using it for a long while. I wanted to put it in my M4, so I pulled it out. It was perfect no stripping on the teeth or any scratches. Wow. This is the best piston/piston head set I think you can buy for a low speed set up. It is almost a perfect seal in all of the cylinders I have.

"If your looking for a great piston thats Durable but doesn't have full metal tooth. This is the piston you should get for your 450 FPS Weapon! Both The Piston and Piston Head are Great Products. But would Recommend something with more stable compression for the piston head if you are running High FPS guns, Aluminum construction Preferably. Full metal tooth pistons can do more damage than good if not paired with the right Strength GearSet. a Great Product from a Well known Company.

"I bought two of these. One for a basically stock setup (minor upgrades...nothing to write home about) and for a high speed setup firing around 45 rps. For the stock setup I give it a five. Works just fine, no hiccups, nothing. Seals perfectly and fit perfectly. For the high speed I give it a zero! After a thousand rounds I opened the gearbox and the pickup tooth was dented nearly a third of the way through. I checked and re-checked every component in the gearbox and everything was set up flawlessly. After 500 more rounds the piston pickup tooth shredded like cheese. If you're going high speed, get something that's nylon reinforced like this one, but make sure it has steel teeth throughout.

"This piston is great except for the fact that the reinforcement around the engagement teeth is large enough to get caught on one of the gears in my cyma m14. It gives great compression and looks great except it doesnt work
