Looking for a piston

[HKGhost]

There is no piston on the market that will last more than 30k rounds, on a high ROF dsg setup. You need to expect the piston to strip as its never designed to shoot that fast. Even the best gun tech using the best parts available can't get more than maybe 40k rounds before something strips. Either you need to slow down the ROF or have a custom piston made, or expect having stripped pistons.

$500 for the Fusion engine
$150 for a Ninja 90ci/4500psi tank
~$100 for regulator + remote line

Other random purchases for nozzles and batteries, tank refills are $5 at my local place, if your playing at a paintball field unlimited refills are covered by the field fee. (I love playing at Picton for this, I never have to worry about air there.)

Depending on what upper I am running on the AR I usually get 4000~5000 rounds per tank.

It is a heavy investment, but SO worth it. It has very little upkeep, and will pretty much never break.

I have put at least 15K rounds through my V2 and 20K rnds through my M240 Fusion engines, neither of them have had ANY failures. The only other AEG I have ever owned that has lasted that long is a stock TM G3A3.

Like I said before, you can vary the RPS and FPS on the fly, and control the amount of air going down the barrel. P*s react very well with heavy BBs and R-Hops, a lot of guys are posting consistent 250ft+ ranges with 0.32g+ BBs.

Glad you added the last part lol
It's not uncommon to see prometheus pistons last over 80k rounds in an AEG, but the gunsmith working on it needs to know what they're doing, and it has to be within reasonable limits.
So far my 249 hasn't munched any pistons on it's own. I damaged one (not stripped) from playing with mosfet settings, but the prometheus lasted from 800rpm at 350fps to 1500rpm at 350fps around 100k rounds. And the system supercore thats in their now has done it's whole life at 1400rpm at 380fps for 100k rounds so far, no sign of any problems coming.

I'd call 1500rpm the upper limit of what's really reasonable. There's just no point beyond 25rps, you've got wicked full auto and real fast trigger response. I've had guns at 800rpm, bolt action, and 1500rpm, and really what it comes down to is trigger response, range, and accuracy. Full auto just isn't that useful.
My PTW does 1500rpm, and it's only ever in semi.

This is the piston I run in my dsg. I switched to these after a couple bad quantum pistons. Have had great success so far but as you can see out of stock at moment. Same as any piston of these various manufacturers batch by batch are different and you have to experiment key is when you find you buy several. For eight bucks who cares.

did you remove the PH bearing? which head are you using? every gram removed is life or death in a DSG (well, as much as can be expected in a DSG)

psssshaw... my p90 ran 15k rounds without PE with a classic army nylon fiber/steel rack piston unswissed AND with the bearing and plates at 30rps without dying.... that is a freakishly well built gun, I can't break it... I've run it semi at full speed for a year now and full auto off and on between 18-30 rps... I'd at least expect a bearing to pop or something like my g36 after 3-4k rounds.

And just to be clear on what is high ROF for me. I say it's really high when you're shooting over 40+ RPS. Anything between 25-39, I just call it "fast". LOL. I have a DSG setup at only 37 RPS and it chewed through 1 piston so far with less than 10K cycles. I have to rebuild it now and to boot up the speed for fun. But I don't expect the piston to last so I'm expecting it to fail. You don't need to be shooting over 30 RPS to win a game. You'll just waste money and time on pistons and labour. Focus on consistency and reliability instead and you'll have more fun with less down time for repairs.

65 RPS with a P*:
polarstar 65 rps - YouTube

Can't imagine it's all that effective per-say, unless you're a SAW, you'd be reloading far too often.

Still, for shits and giggles.

What is this 'bad rep' that comes with P*

I was one of the first CDNs on the pre order list (probably right behind wildcard) and have been closely following the community for the past few years, the only 'bad' thing I EVER hear about the P* system is the remote line.

There are definitely bad users out there who abuse the system, but that is not the systems fault :P

In theory the max RPM of the P* is 11 760 RPM, 196 RPS. Though these setting are impossible for the FE to work with, the nozzle does not even move. I have seen vids of guys shooing 70+ RPS w/ electric feeding.

[Forever_kaos]

Most of the "bad rep" I've heard is from the states. Supposedly a few events ban the system, stating it is "Too easy to cheat" or some silly such.

[ThunderCactus]

People don't like it because it's GOOD.
Just like local players here hate PTWs because they kick so much ass lol
Or 249s because they don't know how to deal with them tactically.

And don't forget, with a DSG, every time you strip a piston, you also risk stripping gears.

Again, bad users and ignorant hosts unwilling to find other solutions. There are many AEGs out there that are just as easy to change FPS.

They say things like, "We're not paintballers" or "We moved away from HPA because we wanted a self contained unit with no reliance on an external power source" or "It takes no skill" etc. Other people don't even know what Polarstar is. But apparently DSG is okay because it's an AEG.

Why should they care, It's your gun. Perhaps they would just be jealous :P

Saying 'we're not paintballers' makes no sense. Do they even know how airsoft started?
Batteries are an external power source.

HIGHLY doubt that. Siegetek case hardened cromoly gears.

OP, you can take SO much material off pistons and still have them run, you'd be astounded, but definitely much more than the previous piston.

I've been tempted by a p* for a long time, but this is a thread about DSGs.
(but yes, I've heard about fields in the states banning p* because people have cheated/they think it's easy to cheat)

[Cobrajr122]

Unless you have a body sitting around that you want to use, I would suggest getting one of the PR rifles that P* makes. Its a beautiful VFC body with the FE fitted by P*.

There is a place in Alberta (I think?) that has them in stock. Try to get one from there as im not sure how to get a full P* across the border. Go to Amped airsoft to get a cheap tank and some QD flexline. Then you can run the remote line covertly in your clothing if that is an issue.

Shoot me a PM or find the P* Thread if you want some more info.

no gears are indestructible. If a chunk of metal piston rack wedges itself between gear teeth, that's a LOT of momentum to be stopping instantaneously.
At the very least, good chance you'll strip the pinion gear.

Bottom line is, it's not good to have pistons break, and you definitely shouldn't be running a setup that you know will consistently break pistons.
Can't be much fun at a game either. I'd rather run a 800rpm gun that runs 100% of the time than a 1600rpm gun that fails every game.

they're as close to indestructible as anybody's found. people who try to break them fail, the handful of people who have broken them have had lemons. RiotSC also makes pinion gears which are just as unlikely to break, so no.

25+ rps is SLOW. its peanuts to make guns faster than that last nearly indefinitely, you just have to keep yourself updated (get on ASM) rather than settling for something inferior. (though the biggest cause of breakage at that speed is still a dumb user holding the trigger when nothing happens. in that respect, nothing's changed.)

also OP, that is a SEXY rifle.
