P90 improvements

>>34585539
Unless you have the magazine feel in sideways, no, because the ejection port is right on the bottom

*feed
God damnit

Tl;Dr no and stupid question anyway because you lose 30rds of capacity.

Sage

Not really, the feed system is totally different. An adapter is possible, but why bother? If you've got time to install an adapter so you can use the 5.7 mags you've picked up (highly unlikely videogamey scenario as it is, desu), you have time to transfer the rounds to your P90 mags.

>>34585539
That's retarded.
It would have to be sticking straight up and sideways obstructing your view.

>>34585539
This stupid 'companion' firearm shit is dumb. And why the fuck should the rifle be the companion to the pistol? Make the Five SeveN use P90 magazines.

Are you alright? Do you have brain damage?

>>34585539
I NEED this gun in 9mm

>>34585539
Why not make an adapter that coild let the 5.7 take the p90 mags instead?

Huh, why hasn't anyone tried using the P90's feed system with another caliber?

>>34585661
>>34585875
The mag would be under the grip, with an adapter that snaps into the grip or on the mag.

>>34587446
Kek imagine how wide the gun would be with 50x.50 BMG

>>34585875
I was mostly being sarcastic.

>>34587446
I'd absolutely fucking love a necked up to ~7mm 5.7X28 case, as big as you can with the case and +P+ the fuck out of it, as much muzzle energy as possible

>>34587851
Congratulations, you just made 7.62 Tokarev.

>>34587446
I needed an engineering project.
Now I'm going to do a 9mm AR upper that feeds like this.

Thanks /k/.

>>34587868
Eh, closer to .30 Carbine given the OAL

Still the only reason the Five-seveN exists was to be a companion to the P90, not the other way around

The CF-05 did that in early versions. However the feature was dropped because it's not really useful. Recent versions only feed from the top helical mag.

>>34588558
nice drawing
totally retarded concept but at least it looks cool

>>34585539
>a better companion to that pistol?
I think it's quite enough that they use the same ammo. no need to have them use the same magazines.
but, if you did want something like what you're thinking of, it would be easier to integrate a P90 mag to a 5Seven / 5Seven mag.
could probably take a 5Seven mag and remove the baseplate, then cobble on a p90 mag to feed through the 5Seven mag and into the pistol

>>34588604
That's what I thought too while drawing it...

>>34588581
>Still chambered in 5.7x28mm
That's fucking amazing, especially with that AutoGlove that's being released, but I'd rather not be spending thirty dollars per magazine.

The only way I see the P90X being improved is lower the height over bore with the sight and polish the machining on the receiver, anyone who owns one will tell you that FN did not machine them really well. Also, having handled and shot one, I have to say I really do like them.

Will the fucking memegun please die.
It's literally just a blowback pistol action fitted to an ar lower. It is not even a non-standard ar.

Went ahead and polished it up a bit so it looks proper in its retardation.

>>34590677
Now the million dollar question is how the fuck this thing feeds....

>>34590173
nigga at least it will actually feed like that instead of being carouselled up the grip

>>34590677
OP here, goddamn it Anon I love you!

>>34590919

Sounds like your in the wrong thread, friendo.

>>34585539
I would make the rail mount a bit better and add an electric trigger to avoid smooshy bullpup disease.

It needs to ditch the blowback and get some damn rollers.

Fucker is way heavier than it needs to be.

>>34585875
Oh shut up. It's a good idea and you know it.

>>34591193
Gas delayed blowback would be perfect for it.

>>34591193
I looked it up, 1.3lb bolt. So delayed blowback could save a bit but not a whole lot.

>>34585539
That doesn't sound like an improvement to me at all.

>>34593144
1.3lbs is a lot for a tiny gun.

>>34585539
Chamber it in 10 meme meme auto

>>34593390
Oh shit I mathed wrong before. I looked up the MP5 bolt weight now, carrier+bolt is 7oz, that is definitely a decent weight saving

>>34587446
I'm pretty sure FN holds the patent

Any updates/thoughts on how to feed it?

>>34596670
Kraut space magic?

>>34590034
So say any of that like it's a bad thing. That's why .300blk is doing well. Would you rather it be a retarded piston gun full of proprietary parts? You could bitch about it mauling brass but instead you act like everyone and their mom talks about it endlessly

>>34591193
But it's not heavy. Not for its size, balance or capacity

>>34585539
I hate summer.

>>34598822
>6-7lbs isn't heavy for a subgun
Uh.

>>34599389
go look up weights of old open bolt subguns like uzis,swedish k or god forbid the thompson or suomi

>>34585661
What if the magazine acts like a stock?

>>34599435
If a subgun weighs the same as an M4 it's heavy. Sorry mate.

>>34599505
>if this facet meets my arbitrary standard, its what I say it is.

>>34599526
>something designed to be lightweight and compact
>isn't more lightweight, less powerful round
Hmmmm.

>>34599585
Weight is similar or less than comparable subguns/pdws while having an extra 20 rounds, being completely ambidextrous, laughably controllable and being better balanced. You don't notice the weight at all because it's tucked in close. It was meant from day one to punch armor and put lots of rounds on target quickly.

You can do with with a Mk18 nearly 20 years later, but it's not as small, has less ammo and shitload more blast. There are only a small number of subguns lighter than the p90, most of which are churched up machine pistols and non are as good.

>>34601212
MP7 would like a word with you.

>Could the P90 be modified to readily accept Five seveN magazines and be a better companion to that pistol?

Almost certainly, provided the feed lips of the FiveSeven magazines are wide enough for the protruding bit of the P90 bolt to fit through. Which I'm pretty sure is true, because IIRC, the P-90 magazines are double stack single feed. You could easily design an adapter that slots in like the original P-90 magazines, and holds a FiveSeven magazine, upside-down, right where the P-90 magazine would feed from.

I don't think anyone would do this, though, because the magazine would be right in your fucking face blocking everything.

>>34588558
>>34590677
>>34589284
This shit wouldn't work at all. You faggots have no idea how magazine's work.

>>34590677
Design-wise, this looks nice. Slightly reminds me of the Halo SMG. Would use.

Function-wise, this needs some work. And I have no clue.

>>34590795
Load a new mag in, flip the gun upside down to pour the bullets in, flip back up and shoot. Repeat flips for each round that needs to be loaded in..

>>34601844
Brilliant.

>>34585539
>P90
>companion to the 5.7 pistol

Except that was never the goal.

The 5.7 pistol is garbage, and the P90 submachine gun stands as its own compact weapon, which you should carry around.

Neither have ammo worth buying.

Get a 1911 in .38 super, then get a 7.62x25 barrel for it. Then, buy a 7.62x25 submachine gun instead. Those guns will actually do what you want them to.

>>34602370
STOP LIKING WHAT I DON'T LIKE

>>34585661
Nah, it would have to lie on top of the gun to feed in the right direction, with feed lips to the rear. Ejection would have to come out of the bottom of the grip. To get a sight picture, there would have to be some sort of raised platform above the magazine, perhaps with an integrated red dot, since that's all the rage these days. And to fit the bolt, since a slide would be impractical, there would have to be some space behind the mag to allow cycling, so we might as well streamline it and turn it into a stock... waitaminute...
