The real truth about ar15 is they run pretty clean unless your running supressed or have a severely over gassed gun as most commercial carbine length tend to be. Thise guns are out of spec and dirty up pretty quick.

A milspec gun will run for about 30000 rounds sans cleaning with only lube. Thats the average barrel life of a milspec chrome lined barrel.

There is a lot of internet hype rumor and plain gunshop good ole boy lies about ar15 pooping where it eats. Makes a great bumper sticker but its hardly fact in terms of it affecting function.

Yes the gas goes into the action but so does a ak47.

Take the dust cover off a ak and you get a massive faceful of hotgas and debris. The fact is pretty much 100% of modern ammo burns pretty damn clean even the cheap soviet steel cased stuff.

No gun runs "clean" not even a bolt gun. Thats why we have cleaning rodspatches brushes and solvents.

Ak47 need to be cleaned and lubed to run properly just as ar15's granpappy's deer rifle and even great great great great uncle jehosephats kentucky squirelly rifle he used to shoot mexicans at the alamo.

Modern ar15 made to milspec standard do not have problems running very high round counts period.

I thought AKs are gas piston, which channels the gas out a different rod away from the action?

Yes they have a gas tube and piston. Some of the gasses get vented out the sides most of it comes back into the reciever bolt area. That is what you don't hear about because the akophiles aren't interested in how the gun actually works just in promulgating myths and rumor to make their choice in rifle feel better.

Gas in all semi autos also come out into the chamber and bolt areas from the barrel itself as pressure isn't fully released before the bolt is unlocked and fully cycled to the rear but that is very minor. You can see it happening at night if you thinking I'm fibbing you. Flame (hot gas) will exit both an ak and ar15 piston or di from the bolt area.

The gas piston doesn't fully seal the action on a ak47 from the hot gasses there no gas rings to prevent that like on a ar15. Yes gas and carbon does hit the lower reciever parts in a ar15 but the critical bolt area is sealed from those self same gasses. What gunks up a bolt face and locking lugs is blowback from over gassing. You get this from guns like dpms bushmasters and lots of other budget guns. Not all ar15 are the same.

So you have some gas out the sides and some in the reciever.

Piston ar15 run cleaner but its a non issue.

What's important is proper lubrication. Your more likely to experience stoppages or failures from broken parts due to lack of lubricant tham jammed cartridges due to fouling.

Ar15 are good rifles so are ak47's its really a toss up just comes down to personal pref on which controls you like better.

You bring up the point that it happens in budget AR-15... does that also apply to AKs? Do higher end AKs like the Arsenal I posted fix this issue?

Watch this video on the unreliable AR15 with the inferior DI gas system.
http://m.youtube.com/watch?v=g2rG8xXfDbg&desktop_uri=%2Fwatch%3Fv%3Dg2r G8xXfDbg

Or this video
http://m.youtube.com/watch?v=Y1kX0nCEh5E&desktop_uri=%2Fwatch%3Fv%3DY1k X0nCEh5E

What about this one?


What about this one comparing the superior AK gas system?

Or this one?

Clearly the AK is superior in every way.

ak47 are designed to be severely overgassed. they have to be to function with the craptastic soviet ammunitiion that has huge variences in bullet and charge weights.

like i said though its not a real issue in either platform. when talking about it its a matter of nit picking than anything else. an arsenal ak will have well cenered sights a good barrel tapco internals you dont have to really handpick like you do with a wasr 10/63.

on the other hand there arent as many arsenals and the spare parts pool isnt very big since a lot of the parts arent swappable with other ak types. quality wise they are on par with most sub 1000$ ar15
