Km4 Ris Gearbox Availability

And the M130 Spring?
On the spring, does anyone have a recommendation on what to use if the KWA is unavailable? I've got some springs, but they're waaaay too long. Considering cutting one of them down, but I'm not sure if that's wise.
I've got a stock KM4 RIS. M120 stock spring that shot 390ish out of the box. (Now down to 342, due to accidentally leaving it compressed on two separate occasions) I want a spring that gets me just over 400 FPS, so that I can hopefully get it settled very close to 400 exactly. I'm pretty sure the KWA M130 is the best option for this, but it's not in stock, and I'd really like to get one in the gun so I'm not being outranged with my 340 FPS.

The SR10 is stock and I was surprised at the FPS gain over the KWA M120 spring. Waiting for the Edgi TBB to be restocked too

lol, 450 FPS...stock everything except the spring.
Gonna see if we can weaken it down to 400-405 to get me "legal" for our games here. If not, I guess I'll be buying some M120 springs when they're available.
^ That's with .20 BBs of course. We have to chrono at 400 FPS with .20 around here.
