FsW-24-J Tecpatl by daisukekazama FsW-24-J Tecpatl by daisukekazama
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.

The only real problem that I can see is that, due to the shape of the magazine, it'd be a pain in the arse to carry more than the one magazine in the PDW without a separate bag or so.
This is true. I figured users might be able to carry extra mags in MP5-banana-style curved pouches. 

But yeah. The convoluted reload process is probably the least realistic part of the design.
looks awsome but makes me think of a bastard love child of a p90 and a FAMAS
Very nice looking and the only thing I can see about the mag not working is ...
Is there some sort of spring in the mag that shots the round up into the barrel?

Very nice work work there.

It's a curved and none clear version of a P90 magazine and since the rounds sit horizontally relative to the firearm it'd actually still work despite the curve. It has a spring like other mag's just can't see it since it's not clear.

Daym love this Firearms design.
Looks like a FAMAS and A P90 had a baby:) im not a fan of the fire selector switch or the handedness, and would it be difficult to reload while in prone position? its an eyecatching and slick design and while low on realism, it is awesome and cyberpunky. I'd have one if you're selling:)
Did you base it on the P90?
Very cool and Shirow-esque and the ergonomics look pretty believable. My only gripe would be the stock looks like it would make for a really uncomfortable cheek weld.
Cool concept!
