>PDW
Whose retarded idea was this? Why not just give everyone M4's?
And if that's not small enough, cut the barrel down to 10''
>>
Because
>>
Because the AR is now the best rifle ever made, people forget what unreliable pieces of shit AR carbines were until very recently, relatively speaking. The whole reason the SCAR trial was started is because CQBRs couldn't be trusted, similarly the 416 was borne of frustration at how delicate M4s were with a suppressor; and even regular big army M4s didn't really come into their own until the PIP and after several generations of mag follower. So that's why, short barrelled ARs sucked.
>>
>>64729037
That's pretty much the best minmaxed option for close protection that's not a handgun. If you want something you can shoulder that's the most concealable package there is. Caliber sucks but it's high capacity.

>>64729088
AR caliber is shit out of short barrels, our close protection details would be better off concealing short barrel AKs which has a caliber that performs excellently out of short barrels. And you can bullpup it.
>muh .300blk
Worse performing round than 7.62x39. Look at them both, the bullet is too big for the small amount of powder behind it on .300blk. It's made to be suppressed because it's actually a 9x39 copy, not a 7.62x39 copy. Again look at the rounds side by side. 7.62x39 has a smaller bullet with more powder, it's a better all purpose round. Still an intermediate, but if you're complaining about 7.62x39 arc wait until you see .300blk arc. Way worse.

The ultimate PDW round is 7.62x39, and there is objectively no argument to this. Handgun rounds are for handguns, when you want a small rifle get the best performing round for a small rifle.

Honestly this. I remember there was bitching about the M4 in the 90's and early 2000's. Also a P90 is easily over a pound lighter and a fair bit smaller than an M4 from the era when it was popular.

.300 loadings of the same velocity as 7.62x39 use a bullet just one gram lighter (7g vs 8g), I think it's fair to call them equivalent.

Some genius basically played the 556 case length like a trumpet until they thought they found what could be coined the perfect PDW cartridge, and they got lost along the way. 357 SIG and what whatnot bottlenecked rounds went flying over their heads. Plus the benefit if magazine interchangeability between the main gun and the handgun. If you use special ammo for 357 SIG in a carbine you'll get around 3000 FPS, and over 2000 FPS out of a pistol.
>>
>>64729126
plus it can ACTUALLY be assigned to any department and be useful
p90s should be standard issue for cops along side their handguns(please anything but the gock- mean glock)
ive seen so many body cam videos where cops struggle with their AR.
not using it but doing anything other than being scoped in and pulling the trigger is a mess
just in every respect.
>>
>>64729139
The SCAR-SC in 300 Blackout and HK437 exist now. IMO the P90 and MP7 still have a niche in being able to be fired one-handed fairly comfortably for use with shields and shit.
>>
>>64729037
Less recoil, larger mag, somewhat lighter, about a foot shorter, and cheaper to manufacture. M4s are cheap because they're using the M16 infrastructure but P90s are mechanically similar to MP5s.

Would blow up the gun. Or double it's weight. Or something equally bad.

See, the P90 is a direct blowback gun. Like a Makarov or MP5 but with a funky trigger setup. This means the chamber can open up while still at pressure and if it opens up too fast the brass with pop like a balloon while still in the gun. Unless you want to be picking brass out of your gun and limbs you need to slow the bolt down.

However, the only way to slow down a direct blowback is to make the bolt heavier. Do anything else and it's no longer a direct blowback. (Side note, this is why we've got all these different actions like Short Recoil and Long-stroke Piston). This can lead to an extremely heavy bolt, possibly heavier than the rest of the gun. +

5.56x45mm NATO out of a 8.5" barrel takes hot steaming shits all over 5.7x28mm from even a 16" barrel.

>Worse performing round than 7.62x39
No.

>The ultimate PDW round is 7.62x39
Comically deluded, it's stupidly bulky even for its original role and performance and entirely a legacy cartridge. Supersonic loads of .300BLK can match M43 performance if you absolutely want those ballistics.

>>64729230
He is greatly exaggerating, but short barreled AR15s tended to often have mediocre reliability until the late 2000s. Seals and Deltas would move from the initial 10.5" barreled CAR-15 variants to slightly longer 12.5" barreled ones, not just because of ballistics and range, but because they found it improved dwell time and reliability.

>AP ammo
That will go through pistol rated armor. Any rifle caliber can defeat that level of armor. 5.7 is just too light of a round and doesn't do well all around. Even when it makes it through armor it barely causes damage. It deflects through light barriers and can't pass the minimum 12" in ballistics gel to be considered a decent duty round.
>>
>>64731531
You can. It's called the RBD.
>>
>>64731359
Show me a more compact gun that holds 50 rounds standard. I'll wait.

>7.62x39 is bulky but .300blk is not

Wtf argument even is this? The rifles are bulky? Ok get a VZ. At least you can fold the stock on anything that's not a fucking AR. Worst PDW option ever, and yes the round is shit out of a 10" barrel. That's half the barrel length it needs to achieve fragmentation.

half of the P90's problems with be solved if it was chambered in 10mm Auto instead of boutique .22 Magnum.

put a Kriss Vector recoil system in the back and it would be a competitive system to compete with short barreled ARs.

higher quality 10mm rounds tear through armor better than 5.7 and still have kinetic energy to do some actual damage afterwards.

FN just wanted a monopoly on a proprietary ammo and proprietary magazines. the P90 magazine is neat but 5.7 still has a case shoulder diameter of 7.95mm, load the same mechanism with 10mm and you will still get at least 40 rounds in the same sized magazine.
>>
>>64731701
>10mm P90

That would be neat, FN should really toy with the P90 design in different calibers. It would only hold like 25 rounds in 10mm though, it's about twice as wide.

I would be willing to take the airsoft version at this point but those are basically unobtainaium now too

>anon says AP was a design requirement

Not very fair. Plus the competition in the program all made proprietary ammo and mags as well.
But I will concede 5.7 is severely lacking in ammo development like other ammo have benefited from.

5.7mm cases are 7.95mm at their widest, 10mm are 10.8mm. so capacity with drop by around 20% or 40 rounds.
>>
>>64731847
10mm Auto was first developed in 1983, before the P90. sure the exotic stuff came later but it already had potential at the time.
>>
>>64731904
Unless you make the mag taller too, you can't pack them as densely so there'll be additional losses besides the diameter.

>>64731904
Neat. Too bad FN is the slowest factory at producing anything and FN USA is not even really affiliated with them other than being an importer and authorized to make cheap plastic handguns with their logo on it.

The cartridges, you fuckhead. Have you seen the case head on 7.62x39mm? It's way wider than it needs to be, and the case could be a bit shorter too.
An AR15 mag with 30rds of .300BLK is indeed sleeker and more compact than an AKM mag with 30rds of 7.62x39mm

Expanding on this further, supersonic loads of .300BLK are almost identical in terminal ballistics to German 7.92x33mm cartridge, but because .300BLK isn't a fucking chopped down 7.92x57mm in form factor, you can get the exact same ballistics and performance but in a much shorter and lighter magazine.

To illustrate this, we have here a Sturmgewehr 44 next to a much later (and much better) H&K HK33 or HK93 rifle. The H&K rifle is in 5.56x45mm but that's the exact same size as .300BLK, and the H&K rifle, with is similar length magazine, holds 40rds of either .223 or .300.
You could hypothetically make similar savings in weigh and size by replacing 7.62x39mm with a variant which is simply a necked up 5.45x39mm or necked down 9x39mm cartridge, giving you the same performance with a .30 caliber projectile but with a slimmer cartridge and thus a lighter, shorter, and less curved magazine.

This wouldn't really be necessary to do, because 5.56mm and 5.45mm already exist and are the perfect type of infantry rifle cartridge, and there's little reason to reinvent 7.62x39mm again when .300BLK, 9x39mm, and now .350LGN exist.

The Colt 5.56x30 round is also like 500 fps faster than the Indian equivalent out of relatively similar barrel lengths

That magazine looks oddly short for 40 rounds of 5.56. How come PMAG 40s are so insanely long?

>>64734239
>the Indian equivalent
Does anyone even know anything about 5.56 MINSAS? I remember seeing one specimen in a video once and it seemed to be almost identical to 5.56 MARS. So close, that the Indians actually plagiarized Nathaniel Fitch’s picture of the MARS in one of their military documents, passing it off as the MINSAS.

>>64734205
Make the grip out of steel and EDM the magwell, and you can feed a COAL of ~1.85” within a comfortable grip. That’s 221 fireball. And if you really wanted you can widen the case head, since there’s still room for a wider case without affecting grip comfort. 7.62x39 can be duplicated (with 110gr bullets) double stacked and fed through the grip. 5.7x28 and 4.6x30mm are nowhere near the limit of what is possible with mag-in-grip guns,

But yes, 5.56 MARS would go hard as fuck in an mp7. Way better than the diminutive 5.7
>>
>why can't everything be an ar15

>>64735076
Similar mag length. But the gap between trigger guard and mag makes it look more proportionate than a 40rd AR's bar graph of 200% mag right next to 100% grip.
