Any fix or downgrade parts or ideas to get the Kriss Vector down to 350 with .20 bbs so its Cqb friendly

The first steps in determing what can be done, we need to what was it chrono'ing at. Just eyeballing the parts diagram it looks like the Kriss uses a rocket valve (part #17)...

If the valve is the same part as other newer NS2 releases (LM4), you could try the Dangerwerx rocket valve. I believe it drops the FPS.

Ditto that.  However...until I have the gun in my hands I can't say for sure.  The DWFV is a good guess though....

Cut 1-2 coils off the rocket valve spring..now itll be cqb ready. To get to the spring remove the bolt by following the instructions in the manual for disassembly. Remove roll pins part #518 and both #516. Theen remove both pins part #92. Then from back of bolt push part #55 cause it maybe stuck..just give it a lil push with a punch or something. Now pull your nozzle out. Then push pin part #517 out. Pull part #15 and #16 apart. Be careful when doing this. Rocket valve and spring may come flying out. Cut 1-2 coils off part #118. Then reassemble and chrono. It should bring you down to 350fps or slightly below.

Dangerwerx valve might bring your velocity down too much..im gonna guess below 300..maybe close to 250 fps..thats just my guess tho. As far as wear to find one last i saw was from evike..but they might be oos

Just an FYI, my experience with the DWFV brought down the FPS in my MP9 by about 60 FPS from about 400 to 340.  YMMV with the Vector and it does void the warranty as Allizard has pointed out.

Call KWA and ask them what spring would be a drop-in replacement.  I'm guessing that it is one from the MP7 or MP9 or LM4....not sure which though...

Ok updated....... I cut 4 coils and went from 380 with. 20 to 360 but I left it a touch high cause I only shot 50 rounds threw it so I think 10 fps will drop after breaking.

Surprisingly the spring was about 1.5 inches, and I cut about 2 coils off to start and it did nothing so I ended up calling another 2 and then it dropped about 15 fps

Hi guys! Jut got mine today and have the same problem here in the uk!
All our sites are running 330fps so kinda stuck with a gun I can't use!
It was suggested summer to use summer gas ( hfc134). And kwa don't ship to the uk so I can order spare! Will chopping the valve spring work?

Yes..but do a little at a time and test..you dont wanna take too much off and be shooting too low of fps
