Why do ARfags want direct impingement over a piston setup, assuming

So you're saying most ARfags would prefer a piston?

From what I've learned most would prefer direct impingement.

>>28617282
Other than the shitty anology, there is nothing wrong with DI. It can be just as reliable as any other setup as long as the recoil spring is strong enough to push through the carbon buildup.

"shitting where it eats" is not valid since firearms can't get diseases or infections.

>>28617282
Because the AR is not set up for a piston.
No rails to ride on.

AR is more reliable than you think.

>>28617295
I know I made this thread with a negative tone, but I'm looking for a confirmation of if AR owners prefer piston or direct impingement.

I've heard some companies mess up on the piston (Eugene stoner himself couldn't get the piston system to work), so let's assume a quality piston.

>>28617321
Rails to ride on? What do you mean? Some companies sell a long stroke piston gas system which helps the AR run cleaner.

What are these riding rails you speak of?

>>28617332
>piston
>cleaner

this is objectively wrong

add more shit to gun == more shit to go wrong

>>28617337
Oh shut up you know what I mean, a piston system puts the carbon buildup above the end of the barrel instead of in the receiver.

So it separates your trash.

>>28617332
The AR bolt carrier is round. The receiver extension is round. With DI, the force goes straight back, and the BCG just slides back.

With a piston, the force is applied differently to the BCG. With rails to ride on, the bolt will only be able to go straight back, not bind up (carrier tilt)

Most carbon build up comes in through the bore.

>>28617346
the DI system actually takes the trash out of the gun instead of just cramming it somewhere else inside the gun.

do you think those holes on the BCG at the ejection port were just for looks?

>>28617352
Primary weapons systems AR15's claim their system eliminates the possibility of bolt carrier tilt in their piston AR's...

Can anyone confirm? I always have trouble believing anything that comes from the company I'm buying from

because di is just a lighter piston

are you retarded?

The gas key is a piston. It enters a recessed cylinder. I own precisely one piston AR, I'm good thanks family.

>>28617371
pws is lying because you can see the carrier tilt in their own youtube videos.

https://www.youtube.com/watch?v=8j_jMVynheY

carrier tilt is a meme or for shitty ARs.
I've seen 416s that have run more than 100k rounds without any tilt wear in the buffer or receiver

Have you ever looked at the bolt and bolt carrier of a piston rifle, say an SKS after shooting ~150 rounds out of it? Its fucking filthy.

Anecdotal, but guns get dirty no matter how they operate.

>>28617365
>honestly thinking bcg ports are more effective than pistons


holy shit nigger there's still an abnormal build up in the receiver you fucking retard

>>28617371
There are ways of mitigating carrier tilt.

But your still going to have a less accurate rifle.
And the carrier will still tilt some, just not bind up on anything. This will lead to different wear patterns, not that this is likely to cause premature failure.

If the DI system was so bad, how come essentially the entire world has adopted it?

gee bill, wonder how the fuck this gun got so dirty - must be the piston

>>28617392
>abnormal build up

piston AR and DI AR have the same amount of build up in the reciever you stupid cunt.

The only thing a piston does is now make you clean an extra part of your gun.

>>28617393
>If the DI system was so bad, how come essentially the entire world has adopted it?
wut.

>>28617392
Have you ever fired an SKS or AK? ARs wind up cleaner after the exact same number of rounds.

Piston is a placebo.

Sorry I'll ask this here because its still a new thread. What else could I have done?

Anyone defending DI is just trying to defend the AR itself.
It was a stupid idea to have the gases and all that bullshit go directly into the chamber and bolt carrier group.
A piston obviously would make for a more reliable weapon, which is why they make piston ARs now.
>>28617319

>>28617387
>Have you ever looked at the bolt and bolt carrier of a piston rifle
The point of the piston is to keep that shit out of your bolt/chamber. It's much easier to clean the piston area on an AK/SKS than it is the gas tube/rest of DI system in an AR, not to mention it doesn't shit directly on your BCG on top of it.

Not trying to start an AK vs AR, but the piston system is far superior, and will keep your weapon running longer when it counts.
If you want prescison/ergonomics, get an AR. If you want reliability, get an AK.
>inb4 watch this video of a shit quality AK getting dipped in rocky mud and failing.

>>28617413
The AR-15, you might have noticed, is used by most first and many second world nations around the world in law enforcement and military roles.

piston will improve reliablilty because of the usually stronger force.
it prevents temp changes in bcg lessening fatigue.

you basically want piston for cold weather

DI uses gas to push against the bolt carrier. Think Hakim, MAS, Ljungmann.
The AR uses the gas to push against an internal piston. It is in no way a DI system.

ALL semi autos get crud in the chambers since the action opening draws crud out of the barrel and into the chamber area.

good deal on the aa though, kudos

Man I wish people could step back and defend the truth, instead of defending what they happen to own.

Piston >>> DI

But while DI stays true to the original model, times change, Eugene Stoner wasn't the worlds savior. He even tried to get Pistons to work, but he failed.

>>28617282
The AR-15 doesn't use true DI, the BCG acts like its own pseudo-piston. Also, piston AR's use a gas system the upper and BCG were never designed for, which causes even more carrier tilt than carbine length gas systems, which in turn can lead to a shorter service life. If you want a short or long stroke piston, don't buy an AR.

>>28617332

I love both Piston and DI AR's. My current planned build that I am buying for right now will be a custom 17.7" barrel with an Adam Arms piston system.

It's depends on who manufactured the gun and piston. Yeah I would love a piston, but if it's shit tier I won't hesitate to pick up a noveske instead.

>>28617282
Piston on AR does nothing to fix its main problems:
1. Shit mags.
2. Small bolt overtravel.
3. High angle of round feed.

It is solution to nonexisting problem.

An AK has incredibly loose tolerances compared to AR, the piston isn't what makes it more reliable.

No John, you are and idiot. The system is not a true di system as it forces gas into the BC and pushes the bolt forward instead of just blowing the bcg back

>>28619570
>AK more reliable than AR
>muh tolerances
this meme needs to die

>>28617498
Even gun Jesus explains it that way

It's how the rifle was originally designed, deviating from that will inevitably lead to unintended consequences.

Carrier tilt is the most notable of these.

DI gives a more gradual recoil impulse which increases shooting endurance for smaller shooters, youths, and women.

DI is quieter in piston guns if you can tolerate the suppressor gas coming past the bolt because of a phenomena called "piston pop"

DI guns are lighter because they don't have a piston weighing them down.

There are many more reasons than this, but these are the ones which clinch the argument for me and sway me in favor of DI.

DI is inherently more accurate, and recoil can be lighter. DI isn't nearly as meme dirty as people think it is.

If you want a piston AR, invest in one of the civvie spec AR18 projects.
