Can a 20 inch AR use steel cased?

nope. only 7.5-18 inch can use steel case.
becouse of the rifling being longer it wont cycle reliably with rifle legnth gas tube

Damn that sucks.

>>31903787
No because each shot adds a little bit of steel to the end of the barrel so it will be way too long after only 1 mag.

>>31903884
You actually believed that?

Why wouldn't it be able to use steel cased?

>>31903814

The fuck are you talking about?

The type of metal in the case has nothing to do with the rifling, nor the gas system.

Of course, if you're using low quality ammo with weak powder charge, then okay, that's one thing, but it has nothing to do with it otherwise.

Actually no, the steel case won't pass a 20 in ar's magnet test. Sorry anon, steel cased will break your gun.

>>31903934
Noguns pls go

>>31903986

Pffft.

Go on then, properly explain how steel case wouldn't work in a 20inch AR.

How does the rifling being longer make it cycle unreliably. Explain.

>>31903986
Then you need to leave

It's already been laid out in the thread for you, retard. Why don't you spend some of your hard earned autism-bux on a gun so you can learn these things?

jesus christ.

yes, any AR can use steel case. the only questions are:

>how reliably will this ammo function
>how long till it fucks up my gun

steel sucks. save your shekels and buy brass. if it were good enough for the army to use, they'd use it.

Lel. Alright, well I guess that's open-and-shut on that case then - I was hoping you could at least entertain me with your attempt at trolling for a little longer.

Meanwhile, if the OP is genuinely stupid enough to still need a further answer:

I really just wanted to bump the post some because good shitposting can come of this, but I wasn't even the anon who said something about reliability concerns.

>>31904104

¯\_(ツ)_/¯

Steel case was designed for the ak which has a 16" barrel, the 20" barrel is too long and the bullet will slow down and get stuck in it

>>31904267
this is true my grandpa personally knew mikhail kalashnikov he said it was so they wouldnt use captured ammo

>>31904000
he's fucking joking, dude. calm down, 4chan isn't that serious.

>>31904000
Jesus dude, I have autism and I could tell that was a troll

the fucking butthurt is real

>>31903787
Yes, the issue arises only with carbine length gas systems due to the fact they cycle so quickly you can run into issues with the harder to extract steel cartridge getting stuck

>>31903787
yes. it'll run fine, assuming your gun isn't shit-tier.

ignore all other responses.

Falling or pretending to fall for bait truly is the best bait.

So a 20 inch will cycle steel cased better than a 16 or 14.5?
