FsW-24-J Tecpatl SMG by daisukekazama FsW-24-J Tecpatl SMG by daisukekazama
Featured here! Drawn as a commission by the awesome :iconnd-2500:. Check out his gallery. I command you.

A concept weapon I've been working on, with the guiding philosophy of 'screw realism, go for looks and wrap it with cyberpunk technobabble.' That said, I actually built the grip in clay before I modeled it, so it works - honest!

By the by, I was going for that 'moral-gray-zone government paramilitary unit' (i.e. Shirow Masamune) look, so if you get that impression I've succeeded.

Falkenhayn Schram FsW-24-J submachine gun. Caliber 6.2x25 mm, gas operated rotating bolt with a proprietary 'ArcMag' system (basically a P90-esque magazine with the bullets staggered in an arch pattern) to streamline the weapon and keep it compact. Combined with a single-point sling, the weapon can be concealed under a loose jacket or even inside a sports bag.

The weapon is 648 mm long and 204 mm high, smaller than the popular MP5 by a good inch or so. The barrel length, on the other hand, is a whopping 333 mm - one and a half times longer than the MP5A2. The ArcMag holds 40 rounds. Other features include a detachable STANAG rail, ambidextrous controls (can be field-stripped and switched over), a suppressor, a two-mode sight with options for 50 and 100 yards, and a light-fiber front sight.

As for the innards, the Tecpatl ('obsidian knife') has more in common with Eastern products like the Russian 9A-91 than any Western firearm, owing mostly to its East European design team. Fire rate is a modest and controllable 750 rounds per minute. The 6.2mm Rodega cartridge - developed from the Swedish CBJ - balances stopping power with armor penetration capabilities for desirable ballistics in urban conditions. The recoil is very light, and the weapon is reportedly very controllable even on full-auto.

Falkenhayn Schram is © me 2012, I guess.

I like the idea with the stackable horizontal clips. Or at least it LOOKS like it ought to be stackable for portability in an ammo pouch.

Ive thought about this very thing with the usual P-90 style mags. How it could be possible to turn it into a Quad Stack or reduce it down to a Single Stack for the last few rounds . . . so that you can make an indentation on the end of the magazine under the ammo feeder so that the ammo feeder of another magazine can snugly fit under it.

As for it being 6.2x25mm, and because of the unobtrusive position of the magazine . . . you should consider making the bullet cases Fatter. That means even though its only 25mm long for the cases they hold alot more powder and punch like a full size 5.56mm (because the length of a 5.56mm casing has been compensated by width).

Then just make the magazine fatter to accommodate them.

I did this idea with a Pistol I designed . . . since a Sidearm is a solder's option of last resort it damb well better be able to do its job, and it doesnt need many shots either. You use your pistol to get your rifle back. So I just made it a slightly shortened .50 AE, tapered down to 9mm. So yeah its a 9x28mm pistol but that case is a fat 13mm wide and punches like a .44mag. And the 9mm slugs it uses are heavy bstards from the VSS. So it penetrates like a jock on a prom date.

So P90 and FAMAS had a baby by the looks of it.

Nice weapon design.

The P90 and the 9-Weapon from Ghost in the Shell, actually. But thank you.

At first: The weapon looks very cool and ergonomic. A safty on both sides of the weapon is also very usefull. I would do the same for the charging handle. Must be possible with this design and its much easier to fix jam when you switched the aiming position. 

I see also few disadvantages. One is the magazin. It looks cool and streamlined if you said, but I can imagine that it isnt possible to reload fast and the extraordinary bended form, dont fits in regular magazin pouches. The other problem is the iron sight. The mounted rail is to high or the iron sight to low, so I have no backup, if my main sights a broken.

Anyway, its a cool looking weapon. Maybe you can fix the problems.

I like the weapon, but it would be unconfortable to reload the gun.

I like the magazine concept. Pretty strange and cool

The magazine would be too awkward to use in practical conditions. In order to load you'd have to move the weapon away from the body, then either look down to line it up properly in order to seat it and rotate into position or fumble around with it.

Artist answer: Pooh pooh realism and practicality it's all about the looks! >:D
Engineer answer: The shortcomings are surpassed by the benefits of this layout. Aftermarket parts could be developed to improve operability! ;)
Honest answer: Yeah... I know. I sort of pretended not to notice because the idea was too cool.
