how is the pro win box, with regards to airseal. som tests would be very nice, with the M100-M170 springs they say the airseal is much better and gives a nice power improvement.

I get about 425fps with the included M130 spring. It's not any better than the custom gearboxes that I typically assemble, but I'm sure at higher spring levels, the air seal improvement is much more noticeable.

does pro-win have a website, ive been searching for a while and cant find them.
im allso buying a prowin hopup chamber for my spetz.

Pro-Win is a PGC brand.

I love my pro-win gearbox so much... I think I'll get another one. The 8mm one.

im going mad here, i have been looking for and trying to get a damn pro-win 8mm gearbox for a few months now.. where the hell can i get one, no one in canada has it, and i dont want to order one from overseas only to get it taken by customs.. >_<
*strokes his HK416*.. soon my baby, soon...

I have one sitting beside me...

Tell Ken @ 007 to hurry up with my PTW, so I can decide what to do with this Pro-Win... lol

you could sell it to me :rolleyes:
oh and i could also use that 247mm tightbore inner barrel you got
about that prowin, is it the 7mm or 8mm version you got?

its really too bad, i got all this money, but no one have the stuff i want.

I have both.

The 7mm one is fully assembled, with custom fitted Prometheus piston.

The 8mm one I haven't even opened yet.

Y'know what? Let me think about it for a bit... if I decide to disassemble and sell my SPR, then you'll see it go up in my sales threads.

i just want the 8mm version as its been updated from the 7mm and is better for using aftermarket parts.
cash is not an issue at all so ;)

Hmm... that's interesting to know... makes me want to keep the 8mm version that much more....

HHAHHHAHAHA


i'll get back to you on it. haven't had a chance to look at my setups
