Would it be stupid for a military to adopt 40 round mags as standard issue...

>what are belt fed machine guns

Damn retard of the day award

30 = standard capacity
40>30
40 = high capacity

20 is perfect for full size cartridges. Not for low-intermediate like 5.56.

20 is standard

No it isn't.

It isn't 1965 anymore.

Everything is geared around 30 rounders : magazine pouches, bipods...
Too much change for not much improvement

It would make more sense to swap to those 60 round coffin mags. The Marines are already moving to a 60 round drum mag for some weapons. Frankly, because of the marginal weight saving and added bulk, I would recommend going out with a drum in your weapon and all additional mags as 30 rounders which are easier to carry on a vest.

This. Coffin mags are the obvious choice.

I'd rather be fed by a 30 than buried by a 60.

That's why you go to the 45 degree angle to offset that extra length.

The army moved from the M16 to the M4 in large part because of the advantages in mobility and stamina granted by a lighter and more compact weapon. Sticking on a longer magazine just makes the weapon heavier to hold and more awkward to handle in nearly every situation.

40 rounders are obnoxiously long and hamper mobility. They are hard to store on your gear because they're so damn long that they eat up a lot of real estate, and the length makes them more awkward to quickly draw from a pouch. They interfere with bending over/to the side if they're on a chest rig or plate carrier cummerbund, and they interfere with admin pouches on the front of most plate carriers. They would never work on a belt, unless you like to wear impossibly restricting pencil skirts made out of 2x4s.

Double stack 30 rounders are the ideal balance between footprint, weight, and capacity.

if standards change why isnt the AR15 an assault rifle

Because it still isn't select fire?

there's no standard which says it needs to be

If standards change, why isn't a watermelon a football?

The only way it could possibly make any sense is if they're swapping from an AK platform to the AR and don't want to change their LBE.

So if 20 is more ergonomic but lower capacity
and 30 is enough ammo but not ergonomic for prone

would a 25 rounder solve these issues? would it be the sweetspot of mags?

main issue as many others said before would be going prone. but for stuff like room clearing or some kind of urban combat it probably wouldn't be terrible. I know that 45 round RPK mags are used often by Russian and former East Bloc soldiers a lot in AK 74 rifles.

I have been an Infantryman longer than Jow Forums has existed and I have literally never ever had a problem with 30 rounders prone.

That said, my 11Z ass hasn't really had to prone for a couple years now

Except the definition of an assault rifle.

are you just here from reddit because there was a shooting two days ago

It can be if it's select fire.

Why would someone come here from Reddit? Jow Forumsfirearms and Jow Forumsguns is ten times better than this place because most of the content is focused on, you know, guns and not stupid anime bullshit and pissing contests about equipment no one on this board has ever touched.

Because the AR-15 was never an assault rifle. You're thinking of the M16.

>Because the AR-15 was never an assault rifle.
Wrong.

>never fired an ar15 prone with a 40 round mag

Why don't you go out and see for yourself why.

Try shooting your AR from a prone position with one of those things in.

Also it messes up the asthetic. 20s are really all you need unless you're kicking down doors in Fallujah.

25 would be better overall.
A bit more capacity than the 20 rounders, but not as unwieldy as the 30s in different positions.
Also 20s are more aesthetic than 30s, so a 25 would be middle aesthetic.

It's harder to shoot in the prone with a 40 round mag, plus they're probably hard to move with if you have some in pouches.

Then go back there.

Your mum handled my 40 rounder

Please go back there thank you

I think Strike Industries is coming out with a 33 round magazine.

Underrated

waaaaaaay too fucking long sticking out like that and the little bit of extra weight isn't worth it

its not even aesthetic. it just looks stupid and wrong

True king of polymer mags coming through.
>fully loaded more ammo than stanag
>downloaded same capacity as stanag

>Strike Industries
They'll probably be garbage

It's only 2 more inches of dangle. Really not that big a deal. You just have to start slowly until you get used to it.

It's also a nicer number.

>not prime
>not transcendental
>not irrational
user these numbers are rubbish

>assault rifle
There is no such thing as an "assault rifle"

30+1 is prime, so there's no reason to change anything at all.

we're talking about magazines here, not belts. Besides, both firearms serve different purposes in combat. Any belt-fed machine gun is designed for more effective grazing/covering fire for the most part, whereas service rifles are good for accurate fire.

Use mine as a monopod. Actually helps in the probe position.

But yes there is you fucking idiot, an assault rifle is a well defined concept. An assault weapon is an ambiguous term invented by politicians to sound scary. Take your own shitty advice in your picture or even better just neck your worthless self next time you think you're smart.

35 rounder would be perfect

Because no one calls a watermelon a football

that's not an argument there's a shooting every 2 days in America

20 is perfect. You're not hosing it on full auto, and 20 rd straight mags are reliable without needing 50 yrs of r&d on anti-tilt followers.

Go back to plebbit. The AR-15 was originally a select fire rifle, the air force has a shitton of them.

25 need anti-tilt followers to work. You get the unreliability of a 30 rounder without the capacity.

this reminds me of the time when my uncles did this shit inside my grandparents' house and broke the tv this way
