Why do ARfags want direct impingement over a piston setup, assuming the piston setup is quality.
Do ARfags just enjoy eating where they shit? Are these the type of people who build kitchens in their bathrooms?
>mfw I own a piston AR
>mfw shit threads like this
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.
Because the AR is not set up for a piston.
No rails to ride on.
AR is more reliable than you think.
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.
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.
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?
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
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.
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?
>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.
Sorry I'll ask this here because its still a new thread. What else could I have done?

I know I shouldn't have let him get too close, should I have swung first though? I'll carry a knife in the car now aswell
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.
>It can be
but it isn't
>AR is more reliable than you think.
still not as reliable as piston system like the AK
>the DI system actually takes the trash out of the gun instead of just cramming it somewhere else inside the gun.
>the DI system actually takes the trash and puts it right in your BCG
is what you meant
>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.
AnD here's the guy who doesn't understand how firearms work.
Also DI sucks because it introduces debris and carbon into the chamber and bolt assembly, which leads to issues like misfeeds
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.
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.
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.
I'm not even that poster, but fine, half of the world. Happy?
Short-stroke Piston > DI > Roller Delayed Blowback > Long-stroke Piston >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>Nigger Rigging an unproven piston into a rifle design that's never had one before while not heavily overhauling the bolt and receiver and instead trying to make it drop-in.
>paying more for a less accurate rifle with more points of failure
and everyone and their mother use rolling block (mp5 and g3)
make a map of that
this proves absolutely nothing, and if you look at standard service rifles, DI isnt that widespread is it?
I love my piston ar it's probly my most reliable gun and I have 3 aks
> inb4 shitstorm
>3 DI ARs
>greased, then literally never cleaned until after each of them has had several thousands of various ammo through it
>various other "notoriously reliable" short and long stroke piston guns including four AKs, all original, not some pleb ass US builds
>some have persistent issues despite being cleaned and lubed after every range trip
>every AR with a piston shoehorned onto it I've seen on the range has malfunctioned at some point
>when I finally decide to do it, maintenance of the "horribly overengineered and unbelievably dirty" DI AR consists of opening it up, wiping down the BCG and scrubbing the chamber+bore, no need to even take the handguard off
I think I'll stick with the one that shits where it eats, thank you very much.
>"shits where it eats" still your only argument after all these years
>tfw it's not even an accurate representation of what is actually going on
>tfw DI AR still by far the best selling semi auto rifle nationwide, used by virtually every relevant special force in the world
>meanwhile dozens of special snowflake piston AR designs come, fail to impress and fade into obscurity
Pistonfags on suicide watch.
Hey fuck off I'm not saying piston is better if I could go back I would buy a di
Lesson learned but this rifle has been nothing but excellence for its intended role
>Also post your rifle bitch
>There are people, RIGHT NOW, who still defend buying more expensive and less reliable pistons for ARs
No, piston guns do run cleaner (in the BGG).
And stop using that fucking word! It is objectively cleaner, but it seems that you have bias, and are not being objective.
It seems that carbon and gases come out of mine
They both seem to have the same effectiveness
An AK has incredibly loose tolerances compared to AR, the piston isn't what makes it more reliable.
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.
I own a piston AR. My buddies bought piston ARs because of me. Only 'mod' was a heavy buffer which also lessened felt recoil somehow. Pic related
>not Thumb Over Bore
jesus christ senpai desu
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.
I've had more piston guns jam on me than DI guns. Though I am looking mostly at m249 versus m16.
>even mentions the ak rekt by mud video
wew lad, they're just guns. You don't need to Lorax for them, just get the better gun.
