Apparently its a more efficient gas system.. Don't know anything about it but they way they advertise it is that it is nothing but a good thing. Any negatives to something like this?

It just replaces the direct impingement gas system of the AR with a more common gas piston system. It isn't necessarily more efficient; but it is a little less susceptible to different barrel lengths and suppressor backpressure usually.

Don't know anything about the Ares model. years back.

You mean other than it is made by Ares? This company has the hands down worst record for turning out any product is has advertised. Can anyone say "Shrike"?

Other than that, it's not the only piston out there...
 
Who makes another one? I haven't found anyone else that makes a retrofit. I am assembling an AR now and I would like to try it out. I have never liked the DI gas system of the ARs. The gas piston seems capable of better reliability.
 
I think it's nothing but a good thing. From what I've heard, you get the accuracy of an AR with the reliability of an AK.
 
i like to play with rifle parts. i have a couple with adjustable gas blocks, pneumatic buffers, nonstandard coatings, springs, stocks, barrels, etc. heck, i've got 5 different match triggers (3 of which are back in the bag after trying them out) and right now i'm almost finished building an AR almost completely out of carbon fiber.

but piston uppers on an AR just seem like a bad idea to me. couldn't tell you why, but i have no interest whatsoever in trying them out, even though i really loved the one on my HK SL8-1.

also, just an observation, but MOST of the upgrades i've seen for "reliability" and ALL of the upgrades i've seen for "accuracy" have made the guns less reliable.
 
POF-USA makes the uppers that DSA and Bushmaster (and i'm sure others) resell.

Lifetime warranty on 'em (if you buy from POF).

The Ares retrofit kit would be a nice addition, IF you can find one.
 
I think BM is using the first one that POF came out with, and POF is on their third one.

Dont know for a fact that its true, but have heard it several times. Could be as much of a myth as the rapid fire magazines mentioned by the media.
 
Do gas pistons detract from accuracy?

This isn't a Garand/M14/Ruger/M1-style heavy op-rod, but what does it do to vibration, etc.?
 
Not to mention the lack of spare parts, inability to interchange with a standard AR if the need would arise and finally the fact that if an AR was supposed to use a piston then Stoner would have given it a piston. :neener:
 
Seems like forever ago when I posted this, I personally wouldn't buy one. The AR doesn't need it, and what if something breaks in this setup, would be hard or possibly very expensive to replace parts.

As for accuracy I have been told that it would not affect it much, as the bullet leaves the barrel before the bolt is unlocked
 
I guess a factory built piston driven AR from Colt, LMT or Noveske would be nice, but the DI systems works just fine for me.
 
One downside is that in the DI setup, the gas blown into the carrier is used to push the bolt forward to remove the stress from the locking lugs as the bolt carrier is forced to the rear. This prevents wear on the locking surfaces of the bolt and the barrel extension, prolonging the weapon's useful life.

The piston ARs do not have this feature.

Replacing 2 parts with 7 or more parts to do the same job isn't exactly the definition of efficient.:rolleyes:

It makes some sense on short barreled and suppressed rifles, I'll give it that though.

Yeah, the first time I cleaned my AR, my reaction was, "That's all that's in there? How cool!"

You know, while the AR may need cleaning more often than some other guns, it doesn't take a deep cleaning, just a little wipe. And there's not all that much in there to break. I can't help wondering if that skinny little piston isn't a pretty major point of failure that the standard AR can do without.

And while the big op-rod on my Mini-14 isn't going to break any time soon, stress from it does seem to rattle other things a bit.
