ar-15 gas piston?
does any of you own or have you shot one of these?
for those that do not know, this is a gas driven piston that replaces the gas tube, instead of blowing gas into the receiver, it uses a piston rod under the forearm that cycles the bolt, no gas, heat or carbon enters the receiver, and supposedly allows the gun to be shot several thousand times before cleaning, but it's pricey

I have shot one.
I wear the electronic ear muffs and noticed that the spring recoiling noise that is ussully in my ear was gone.
I didn't think it cycled any better or worse than my old style AR.
How much is one of those things?
i have never looked.0 -
bushmaster is selling the complete gun for, are you sitting down?
1,600
but i found a retrofit kit for 400, it is not supposed to do anything but enhance reliability, and cut way down on the need for cleaning, i saw one disassembled today, it was intriguing, my friend that works for blackwater in iraq swears by them, and that is what they issue, because of less cleaning and less oil

Now how close does that resemble an SKS? 0 -
tried one in the desert. I think the upper was made by HK. shot about the same. I seem to remember it being a little heavier. You're right about not having the "twang" in the stock. 0 -
I have one made in 1988, it's called a DAEWOO.
It's amazing how I've been a fan of gas piston operated rifles and for 10 frigging years have been told..."It don't need one" "Gene Stoner would've put it on there if it were necessary" "Just clean your gun" etc...
Everything old is new again.

saw an add for those from another co. also and was wondering if the higher price was worth it and how it handled 0 -
FWIW,
I carried an M16 for 18 mos. as a grunt in Viet Nam and can't remember ever cleaning that little gas tube, or anyone having a problem because of it. We fired a LOT of ammo through them, not all in combat situations, and it was never a problem. If I was getting an AR today I wouldn't spend the extra for the piston thing.0 -
It's designed like that so the bolt stays cool and theres no build up on the bolt. This keeps it very reliable. If you get some dirt in it, it keeps shooting and wont jam due to the bolt staying cool to the touch. 0 -
Midway was selling Adams Arms carbines piston type uppers complete for $600+. I got one and it worked fine on my Windham lower, just bought an Adams Arms lower for $299 on GB. 0 -
I own one, but haven't shot it yet. Adams Arms 14.5" evo 0 -
I've shot the SKS equivalent. Works very well. Time tested concept. 0 -
Maybe they have fixed it by now but there was a problem with tilting bolts on the conversion kits.
The rear of the bolt would gouge the heck out of the buffer tube.0 -

First....thank you for your service.
Second....I don't think they are talking about the gas tube getting dirty....it happens. They mean that the crap doesn't stop there....it goes back into the bolt, carrier and receiver. The piston models do not get all that mess back there.0 -

The Sig 556 is a piston AR and I have seen one used go for $1100, in very good shape. 0 -

Have always heard the original design was with a gas piston, but the Army had it changed to cut costs.
However Stoner did design the 'AR-18' with one.

You can still get a Stag gas piston for around $ 1,000.00.
This price has been fairly constant for 3 - 4 years.

The early Piston guns had a problem with bolt carrier tilt as most of those used a bolt on key.
These were not as reliable as the new one piece setups. For those of you concerned with the spring slap of the AR butt stock that can be eliminated with a $1 plastic sleeve/washer available almost anywhere.
There are pros and cons to the discussion with gas vs the piston. If I was using my AR in an extremely dirty environment I'd go with the piston. Since I probably never will the gas system will suffice.0 -
I'll take a DI gun any day. I see no need to switch to the piston popper. I have a friend that has the Sig piston and it couldn't hang with my beat to hell 14 year old 14.5" chrome lined bushy when it came to accuracy. Both of us just bought 18" White Oak barrel and both will be DI. 0 -

That was another con to the piston guns. Apparently that was another knock on them that they weren't as accurate as the gas guns were.0 -

Funny how people thin k a gas piston AR runs cooler and cleaner. I have to laugh at that. 0 -
Blasphmey.
No need to AK up your AR. Just get yourself an AK74.
But really who here has troubles caused by di?
If your planing on shooting 10,000 zombies between cleaning then maybe.
But I think most of us civies will never push an AR that far. I bet most of us clean after every outing.
They only up side I see is the issue of firing an AR that has been in water.
Fire a di full of water and its new parts for you.
But how many of us play navy seal while target shooting?
I think the money would be better spent on better quality parts vs a piston system.
Less weight also.

If you want to make your rifle heavier and less accurate, then by all means go piston. I am sure that as we speak DI guns are racking up raghead kills. The MK12 MOD whatever sure don't use a piston popper[8D] 0 -

The significant point I got from his post was that he fired a 'LOT' of rounds through his rifle and experienced no problems.0 -
I've had an Osprey Defense piston kit on a 16" upper for a couple years ... there is a weight difference but its only something like 2 ounces not enough be concerned with, there is no "twang" ... I do like the fact that it runs cooler and is easier to clean, but is it really worth the extra $$$ ?
Not really.0 -

Ignorance is bliss???
The PWS Mod1 weighs like a DI is neutrally balanced and is priced with the higher end DI guns.
I have DI and piston and the piston can be shot a bunch of times with no cleaning and while a DI can go without cleaning it gets so crapped up I don't shoot them without at least a fair cleaning.
Best thing is go to AR15.com the piston forum and ask about the various models.
The LWRC is like a Mercedes nicely engineered but pricey.
Most pistons are now every reliable with little maintenance required.
The PWS is not typical of pistons on weight and balance as it is based on the Daewoo/AK47 gas system.
To say just get an AK is absurd if want accuracy and a system center to make a great gun. I have had many various AKs and if you like sloppy inaccurate junky guns made for monkeys that barely know which end to hold that is great for you.
I love my DI ARs but my PWS Mod1 MK114 is my favorite gun
