5.88+- mm BB's

[Katipunero]

Besides KSC perfect BB's, does anybody know what other brand BB's are japanese/taiwanese spec 5.88+-mm?

I just ordered some KSC's for my GHK M4 mags which reportedly requires smaller spec bb's in order to fit and feed the mags correctly.

I filed/grinded the feedlips on the GHK M4 stanags for the BB's I have at the moment (Valken's). While they do work, I think I'd want to try and use the designed ammo size for the mag as opposed to jamming in a higher tolerance 6mm BB.

Any insight would be appreciated.

There's Excels from Japan but I believe they are 5.91mm

3 one-hundreths off, plus or minus. I think those are winners.

Maybe don't use Valkens. That's probably your issue.

Yeah, I'm starting to realize the GHK M4 is like a high end car that only runs on 92 + octane gas; in this case, 5.88mm.

My WE m4 has no such issues. I can use any bb and it shoots fine (albeit probably not as tight groupings as with the GHK).

No, you just try to feed you regular car cat piss and stale beer...
