Why 30 rounds?

Probably has to do with springs and the way that mags have to be curved past a certain capacity to feed properly.

>>28504937
have you tried 40 round mags? I've never used one that didn't suck if you loaded it all the way to 40.

It has to do with weight, maneuverability and ergonomics.
Sort of like cars and gas tank capacities, it would be retarded to have a Prius with a 32 gal tank same with a truck with a 12 gallon tank.

>>28504937
30 round magazines facilitate 10 bursts of 3 rounds, which is considered a standard burst length for most firearms.
I assume the trend has continued with other ARs that do not feature a burst setting because of requirements set by governments (magazine capacity for new service rifle must be 30)

I always thought it was because anything longer than a 30 round mags makes it a pain to shoot prone

>>28504937
Well all I know for sure is that uzi mags bug the shit out of my ocd.

But I'm pretty sure the old standard was 20, but Mr klashnikov decided to have 30, so that granteed the US ,at least, looked at having theirs bigger, but couldn't get them to feed well and settled for even.

Another gun that bugged me was the french bolt action rifle with only three rounds. Your only two shots away from not even having a magazine at all.

>>28504960
I have two 40rd pmags for my AR and I've never had a single problem

The Bertier was outdated by the first world war but the concept of enblocs were considered good enough to not need much more and they were better than the Lebels. They upgraded in during so they weren't scomplelty outclassed during.

C&Rsenel does a magnificent job going over the logic of the military for this. https://www.youtube.com/watch?v=yrKN31COHxY

>>28505049
lots of subguns have 32 round capacities - UZI, Sten, Walther MPL, PM12 Sterling has 34, Carl G has 36, I think the idea was so soldiers could download their mags w/o being rendered less combat effective - like when US troops were downloading 20 rounders in their M16's

>>28504937
>why exactly has 30 cartridges become standard capacity for almost every countries magazines?
Because Mikhail wanted to kill a lot of Nazis and 30 rounds gave him a magazine that was not too long, did not curve too far forwards and was probably the most reliable during testing.

Then when the proliferation of assault rifles occurred other countries saw what Russia was doing and how good a system it was and jumped on the band wagon.

The STG-44 had 30 rounds before the AK did.

And there were a number of ~30 rounders in various SMGs as well prior to then.

>>28505236

Did I say the STG invented 30 round mags?

>TO ALL YOU STUPID MOTHERFUCKERS
The magazine the AK uses was developed before it, for another rifle, by another arms engineer. Klashnikov was orderd to use it, he did absolutely nothing to invent it.

probably because the size of 30 round mags was reasonable. do you want to be maneuvering with 50 round mags?

it was a well rounded number

it was high capacity for guns that before only held 5 - 10 rounds

Why would anyone download a modern magazine? Magazines are designed to take the full capacity. I don't see why robbing yourself of half a magazine (with a full load of ~9 magazines) is worth the marginally - if at all - improved magazine reliability.

Because ARfags have such a shit rifle that full mags don't want to seat without slapping the shit out of it, they also like to premature eject rounds if you slam a mag in to hard. You want to slowly charge your ar on a full mag? Lol enjoy another premature ejection

Also liberals

>Magazines are designed to take the full capacity.
Probably just part of the fudd lore that storing mags loaded hurts the springs, and of course we're still excluding ARfags from this discussion because see above

Also liberals again

>I don't see why robbing yourself of half a magazine (with a full load of ~9 magazines) is worth the marginally - if at all - improved magazine reliability.

The Original AR-15 prototype used 25 round magazines like the FAMAS F1 models.

All Battle Rifles (G3, FAL, M14) use 20 round magazines.

The reason why in the West 30 became standard is because a 30 rounds of 5.56mm NATO takes up the same space as 20 rounds of 7.62mm NATO.

Here's a STANAG compared to a FN FAL magazine.

>>28505392
pmags have enough clearance to force in 31 loading on a closed bolt isnt an issue like it is with gi mags

>>28505412
>Maybe you load mags hard. It's a thing.

This is literally the only way to load mags on an AR. It's not like an AK where you can rock+lock it, if you don't load an AR hard there is always a chance of the mag not seating properly if the magwell/magazine is dirty.

I'm not talking fucking slapping this shit out of it like people do, but a firm upward push. But slapping the shit out of it doesn't hurt it at all either, especially with pmags that have the overtravel stopper.

>>28505421
This. Do 27 and see.

>>28505442
why would 27 change anything?

>>28505276
Im this guy
If anyone here is familiar with black or green follower military issue mags. You would know never to load them to 30. The first and second round dont always feed reliably. Now the military issues tan follower mags. These new mags have anti-tilt followers and feed better. But I still dont load any aluminum mags to a full 30, which is all I use thanks to uncle sam. PMAGs work fine with 30

>>28505276

I think he was doing a funny. The first post used the word 'download' to mean 'stick fewer than the maximum possible number of rounds in a magazine.' The second post was using 'download' to refer to getting something off the internet. There were public service ads about piracy that said "You wouldn't download a movie..." and things like that. So he was taking advantage of the fact that, in English, sometimes the same word means two different things. It's always funnier once it's meticulously explained.

2 most common plastics used in 3d printing are PLA (hard, brittle, biodegradable) and ABS (higher temperature thermoplasic used fucking everywhere). Many people will give ABS prints something called a vapor bath, wherein acetone vapors soften the outermost plastic, with the goal of unifying the layers and creating a smooth finished product.
Here, while its "melting together", you take a brush to it to create a bakelite pattern. Let it harden. You can call it a day and paint it, or you can use it to make a mold for a 2 part castable plastic. This allows you to make many on the cheap, and if it breaks, you have a trunkload more. The easiest, most repeatable way to do this is to follow boris (of shovel AK, RPG shotgun, iron glock and plastic glock fame) guide titled "fruity ghost", wherein he and others make silicon molds and play with various plastics to make the polymer AR lower a viable item for more the "square range" use.
