Is there any benefit for having two or more barrels in a gun? Couldnt you just make the rof twice as fast?

From what I've seen on several videos of people shooting twin barrel guns at the same time the bullets get their trajectory fucked up. The guns aren't accurate at all.
Not sure about the reasons why. Maybe the vibration of the barrels affects each other's and the bullet loses accuracy. Maybe the turmoil they cause when they spin through the air affects each other. Maybe some other thing. Maybe a combination.
Whatever the reason, they seem fun but inaccurate. So I don't think they'd be any good for precision shooting.

Funny enough, the Alternator's gimmick isn't even fucking high RoF but just higher damage. Only reason why you'd have multiple barrels is as anti-air as evidenced by all the twin or multi-barrel SPAAGs and shit.

anti-air, as well as air-air and air-ground have their requirements dominated by rate of fire above everything. Engagement windows are so short that it is absolutely necessary to get as many bullets in the air as possible.

So this is done either with multiple barrel actions like on gast-system guns, multiple enitre guns like on many SPAAGS, fast revolver cannons, often in multiples, or gattling type rotary barrel guns.

you are like baby compared to me

But three really fast burst are better? Ie ideas behind a ACR in 80s

The AN94 and duplex rounds went nowhere.

the spas-12 in hl2 fired out of the magazine tube if you right clicked

worked pretty well honestly

But, they're both practically the same gun? I mean, aside from one has heug mags and the other can be aimed.

No and the alternator is a meme. Only good idea about it is that it’s chambered for 10mm other than that there’s no point in using it over something like the auto pistol since the auto pistol is lighter and has relatively similar power overall.
If you want something like an smg take the Car or R97. If you want a rifle that can be compact take the r101 since it can collapse down to the same size.

I think it's from muzzle blasts interfering and causing turbulence

They also had an MP-7 that shot grenades.

This is retarded bait fuckthatshitmate

Two of those,

It's a question of relative advantage. I think there is actually some significant potential advantage.

>weight, complexity, bulk, and yes you can just shoot the same barrel faster instead
those are the relative disadvantages, yes. but volley fire has other advantages which may not be at all insignificant.

like coverage at range, emulated ultra-large bore.

if so it could be resolved with a muzzle device.

if anything the salvo/pulse fire concept just goes that much further in totally obsoleting volley fire than conventional automatic fire.

I think the potential advantages of volley fire come into focus if compared with shotguns. Imagine a pump-action gun which is a ring of .22LR barrels around a central helical drum magazine. Probably 20 or more barrels. Each pump loads all the barrels, and the single trigger fires them all at once. If issues like could be resolved, this would be a gun for CUTTING fist-sized holes out of things at range.
