Ok, first off I am a big fan of bullpup designs,

Ok, I want to upgrade my famas to about 375-400 fps. But I'm not sure whether I can get systema Internals for the v1 Gearbox. Any help would be appriciated.

The V.1 Gearbox can use the same tpe gears as any other gearbox, the same springs, and pistons/piston heads. Things like the spring guide and cylinder head though might be hard to find replacement parts for. I have seen a metal spring guide for the V.1 gearbox before on airsoftatlanta.com but if I remember right they were out of stock at the time.

Whoa, slow down a second here. The Version1 mechbox does not use Ver2/3 gears the best that I know. The spring is replaceable, as is the spring guide, cylinder, piston/pistonhead. The Ver1 gears have a different ratio if I recall correctly. That, along with Version1 parts being very difficult to find and the Ver1 mechbox only fitting a 560 motor, is why people stick to lower-strength springs in the TM FAMAS.

The stock parts will take up to 400fps/.2g level spring, but after you shred the gears, you are out of luck. While not having owned one, there is enough precedence out there detailing this that I would recommend keeping it at a lower spring level.
