Deep fire titanium pistons , not all that great...

Sorbo pad is this little tiny circular pad of sorbothane material that goes into the cylinder against the inside of the cylinder head to help aliviate the force from being struck with the piston. They have them at airsoft parts if you want to have a gander.

Ah. That's what they're called. Thanks.

the DF full titanium finished last in all cathegories.

I would go for the Systema new type or prometheus.

The new Modify Polocarb looks promising too. 7 tooth rack and a nice polycarbonate piston.

I've installed a lot of Modify polycarbs and they are very nice.

I've got a madbull polycarb in my mp5k. I'd give a review if I ever got to use the fucking thing.

I don't know if the aluminum pistons are actually gearbox breakers, although they are VERY comparable in weight to a polycarb piston, aluminum doesn't absorb as much shock. Anyway it deserves to be tested, use a TM mechbox for fast results lol
Anyway +1 on that prometheus piston, I've heard of issue using them with non-prometheus gears, but I've been using prom piston and double torque gears in my 249 for well over 80,000 rounds with minimal wear on the piston

The Prometheus pistons are still king in my books.

I've worked with a plethora of pistons and modified a lot of them through cutting and filing and the Prometheus ones still have the toughest material in my eyes. If I were to compare it to something, I would say it is similar to Tokyo Marui nylon, but tougher. The break on it I could describe as "moist" yet resilient. It's not brittle like almost any other brand.

I've worked on Systema red (old & new), Systema black, Area1000, Prometheus, Deep Fire, Guarder, Angel, PGC, G&P, Classic Army, Tokyo Marui, and countless others that I can't remember off the top of my head.

Prometheus is expensive, but IMO, well worth it.

When I originally upgraded this gun (a loooooong time ago...soemthing like 8 years or so) there was basically TM pistons, Systema alum, the orriginal Systema Red, and that was about it for choices. I had read about the Systema red issues, so I went the Alum route, know that it *may* cause faster wear, but since I was running stock gears, I wanted to see how long they'd last.

Surprise surprise, 8 years later I'm running the SAME stock TM gears that came OEM in the gun. I think that the shimming job + Superlube was the key to success, and I had a great teacher in Cyclic.

To be honest, a number of folks who have used the gun as a loaner have commented on the "kick" (as they call it) of this particular gun - a slower ROF than stock (about 550 rpm) and the extra mass of the piston seemed to make the gun "jump" a bit when firing full auto. It's something that's been said to me by too many people over too many years for me to take as coincidence.

I use to run the systema poly. piston (new/black version).After 200rds teethe were half grinded.I switched to the DF titanium ver.2.No wear and tear so far after 6 games. (6000 bbs).On the side note I'm running it in the Systema Turbo Set.
