I don't get the whole AKS-74U thing.

spoken like a true mong

go away

what is a mong, a mongolian?

>>33513945
5.45 has less recoil than 5.56.
7.62x39 has a fair bit of recoil.

As An "SMG" (it's closer to a PDW or carbine but that's another topic entirely) it has a shorter barrel than most AK-74s.
This means less powder burnt, less force on the piston, and it's already got light recoil to begin with.

And also, in modern warfare, fully auto is fucking pointless outside of LMGs.

>>33513945
cost probably. 5.45 isn't velocity dependent as other cartridges. Shorten piston, barrel, do a new top cover done. Same mags and receiver etc.

>uncontrollable
haha faggot

>>33513987
A mongoloid. Go look in a mirror you'll see one.

>>33514033

What makes you think I am a mongolian?

>>33513994
Now that this post is taken care of, allow me to explain what I mentioned earlier.

The AKs-74u is a PDW concept taken and applied to a carbine.
It was meant to be a rifle small enough to conceal in a cockpit, turret, or next to a drivers seat but still useful enough to be used as a front line weapon in a pinch.

Thus the 5.45x39 chambering (ammo commonality for assisting troops already armed with regular 74s in getting used you out of there) and small size (te soviets actually made holsters for them to be used by HIND pilots.)

It's not really an SMG but an ultra compact carbine.

>>33514057
It's a sarcastic comment comparing you to a member of the Mongol Horde, a joke that implies you are both stupid and a barbarian.

I'm gonna guess you're an underageb&, and not a particularly smart one.

I thought the whole point of it was to be a replacement for smgs, a bullet hose (imply full auto)

>>33514165
No.
In fact, post WW1 and trench warfare, people realized that bullet hoses in pistol calibers were kinda...meh.

Not too many reasons to have them.

Also, Russia already had shit tons of bullet hoses anyways. The Vityaz post 74u and surplus PPShes pre 74u.

It was a PDW carbine, and never was intended to be used as an SMG in any capacity.
The SMG bullshit that comes from CoD is because Ukraine classifies it as an SMG for some unknown reason (probably supply line BS)

Only if you're a skinny manlett.
Real men fire full-size rifle rounds in FA.

funny how every single country on earth rushed to adapt SMGs as WW2 stretched out, with Finns and Germans both paving the road and demonstrating the effects of fully automatic personal weapons.

5.45 has no recoil
5.56 has no recoil
7.62x39 has minimal recoil

As someone who shoots sub 12" 5.45, 9mm and 5.56 rifles frequently I can tell you that they are very controllable and effective (at the right distances with the right ammo). 9mm and 10mm subguns have even less recoil and are basically point and hose levels of easy.

>>33514648
While most were only available in fully automatic, they almost entirely ended up used in short bursts only.

This also lead to the birth of the assault rifle.
You know, the select fire gun that mostly gets used in semi auto.
As an assault rifle.
And not an SMG.

>>33514030
>5.45 isn't velocity dependent as other cartridges
Actually it is you fucking mouth breather, 5.45 has a pretty awful range and performance out of the AKs-74U's barrel, the cartridge really isn't distant from the 5.56

>>33514165
>I thought the whole point of it was to be a replacement for smgs
No, that was the whole point of the AK/AKM.

Soviet war doctrine since mid WW2 was pretty much "fuck rifles, everyone gets SMGs nao". The problem was that SMGs have very limited range, the AK solved that.

The whole point of the AKS-74U was "Hey, maybe we should re-introduce SMGs, because, y'know, as a BMP driver I don't have enough room to stuff long bulky shit into while being able to retreive it quickly when I need to abandon the vehicle in a hurry. And a pistol just ain't gonna cut it, comrade"

>The AKS-74U was intended as a personal defense weapon for tank, gun, helicopter and other vehicle crews,and for the special operations forces, which required compact but relatively powerful individual automatic weapon.

>>33514108
No, its a reference to downs syndrome.

>>33517741
Wrong. 5.45 will still reliably yaw out of the short barrel.

Lolno

Stop doing this

>>33519189
Not an argument

>>33519213
he's right though really, if you look at like afghanistan riflemen don't have to use full auto except for suppressing fire so merely acting as a substitute for a lack of suppressive fire coming from light or heavy machine guns. but be it at 25 meters, 100 meters or 300 meters rifles are mainly fired in semi automatic because of better hit probability when you're actually aiming.

>>33519213
Elaborate.

>>33513945
Ak74u's are absolute shit, completely useless pass 4 yards. The barrels are too short to stabilize those long ,545 rounds, you'll never hit anything. 762x39 is much better for short barrels, but the blast is still an issue. I think they use the krinks because they look cool and it makes offices feel special. If you did get hit by it, it would be very very deadly, but that's literally going to be impossible unless you're stuck in a closet with your target.

>>33519213

Pretty much. Since much of modern combat takes place in urban areas with close ranges not having full auto is a huge issue. Id hate to have to clear rooms and buildings with semi.

armor crewmen and rear guard units needed a more powerful weapon than a machine pistol, but a less powerful weapon than the AK-74. it was cheaper for the soviets to design a tiny rifle that had ammo commonality with the infantry's rifle than to design a brand new SMG from the ground-up.

it's about those two factors: cost and logistics. if the military industry is already producing massive amounts of 5.45, and you already have all the tooling to make AK-74 parts, it's far less expensive to just make a slightly different AK-74.

plus think about their alternatives. they would likely need to make an entirely new cartridge if they were to make an entirely new PDW, because their pistol round was (and is) the anemic 9x18 round. imagine you're a russia artilleryman. do you want the PP-Bizon, or the AKS-74U? I know which one I'd trust more.

>>33520030
Russia is using 9x19, these days.

>>33520116
They do now. They didn't back then.

>>33520193
>because their pistol round was (and is) the anemic 9x18 round
Should have worded this differently, then.

>>33520211
Well, it's not like they ditched the 9x18 entirely. They started to phase it out but it's still in service. Last time I checked, anyway.

Because it's easier to hit while controlling recoil. Using FA happens, it's valid and nobody is saying FA means one has to dump a whole mag every time they pull the trigger. It's usage is contextual, stop being a fucking idiot

>>33519174
That particular loading will, yes. Doesn't change the fact there is a negative impact with shortened barrel lengths.

>>33520280
They did. 9x19mm has been standard for SMGs and handguns since the early 2000s.

>>33520397
Lots of police still carry Makarovs and 9x18 SMGs, don't they?

>>33521655
Not officially. Maybe in the middle of nowhere. MP-443 and Vityaz are supposedly what the police officially carry, there.
