"So far I own 5 of these pistons. I bought two back in 2008 and the remaining three in 2015. They haven't let me down yet and the 2008 two are still top notch shape after of the use they been through.

"I had this piston in a gun running on a 14:1 gear set and a Matrix 5000 series high speed motor. The piston I got was not perfectly symmetrical, and the grooves on the sides got misaligned and jammed up against the piston guide grooves in the gearbox shell. Subsequently, the teeth strip got ripped out the back of the piston and broken in half by the sector gear. I got a second one and have had no issues with it at all in a DSG build. The piston itself is great, but the quality control is a bit lacking.

"This piston is quite weak. In every gun that I have had this piston in, the rack gets ripped out the back even after using epoxy and superglue on the piston rack. Granted my builds are around 400 or so FPS with .25 at around 29-35 ROF depending on the build, these pistons are not as strong as they make it seem. Save your self the time and get an SHS piston. Much stronger and will last much longer. If you want a piston for a stock gun just to increase reliability, this will do the trick. But take a gun techs word and get the SHS piston.

"This piston cracked after 7 hours of play. My setup throws .28s at 400 Fps at 35 Rps. Very Disappointed. I should have just bought an SHS from the beginning.

"First off, this is THE best piston I've ever owned, I have had it in many different setups and I'm currently running it on a 360 fps 28 rps setup and the only wear that I've seen was the black paint in the teeth has only just started to come off and this has been through over 20,000 rounds with no problems. It is pre lightened already but Swiss cheesing it will make even lighter. all in all, 100/10 and if it strips I can just buy a replacement tooth rack from instead of buying a new piston

Extremely durable (as durable as SHS blue piston which are the strongest)
Cheap replacement piston rack (8$)

Somewhat expensive
You don't have this piston

"This pistonbody is what they call the "Forever Pistonbody" for its durability whether you use it with a strong torque set-up or high ROF setup or even combined Super torque up + Lightning speed. It's worth the price.

"Great piston, and three of them are currently powering my KWA M4, Matrix SR-16 and JG G36C gearbox. The piston teeth strip being available is a plus because it is inevitable that the piston teeth and gears grind against each other. The body of the piston are holding up over 20000 rounds without a sign of wear and tear.

The teeth strip is wider than deep fire and other similar pistons which gave my gun a much better seal and appears to grip on my CNC steel gears sets better with more surface.

All and all, great buy and I highly recommend this piston.

"I just got this piston and stuck it in my Matrix PDW and fired maybe less than 100 rounds before the first tooth on the strip broke. Granted I do have a high speed motor, LiPo battery and an m120 spring so it is putting a lot of stress on the teeth. I may have just received a lemon or maybe this piston should only be used for lower powered guns. Either way I am going to try to find a much more durable piston this time around.

"I have had this piston for 3 years and I play very consistently. I am a tech and from my viewpoint this is the greatest piston ever. Literally I have put this thing through 300,000 rounds, most likely more. It has withstood my crazy RPS setups along with my high FPS setups. I recently purchased a matrix turbo motor, (greatest motor ever to live) and I am shooting 430 FPS, with .28 gram BBs, and yes I mean .28, while shooting 32 RPS. You'd say it's not possible, it's all in the compression, and tight bore barrels and the right bucking and nubs. This Piston has withstood my monster setup. It has more than exceeded my expectations. Tonight, it finally broke, not the piston it's self, but just the first tooth on the teeth rack. That's it. I can not describe how much I would recommend this piston. Please stop questioning yourself and buy it.

"This piston is absolutely great. The piston does slightly increase the rof, the metal teeth a very good quality, the only problem i had with the teeth was that they needed to be sanded so it had the same angle of engagement as my stock piston. Since the metal teeth are such good quality, it was hard to sand but it works great now. I'm going to buy another one for my other gun

"Im a big fan of this piston, I've bought 2 of em I'm currently running one in my M16 its only running about 26+ RPS at about 384.4 +/- 2.1 FPS.

My P90 different story however:

SHS 13:1 super high speed
Matrix high speed motor
11.1V Dean plug Lipo
and since Its my indoor gun sadly I'm using an M100

It rocked for awhile except at the back of the piston when the gear first makes contact the plastic cracked and the teeth would be push up and only cycle every so often, I believe I really should have decompressed my spring better to relieve pressure. By not just a single cycle but popping the gearbox out and checking I blame my laziness after a hot day.

"So not too long ago i was building an insane support weapon (m249) and i needed a really high speed piston (stock ones kept stripping)

Here was my setup for my M249:
SHS 13:1
SHS High Speed Motor
Matrix 8mm Bearing Bushings
Matrix shims.
Matrix Cylinder

So i was getting around 35bb/s with the set up and the stock pistons just werent working for me.

So I got this piston and now its shooting 40-45 bb/s on a 11.1v lipo

Light! Fast! 5-10 more bb/s
Full metal teeth

Since teeth are full metal, it will strip your gears in the case of a gearbox lockup
