SIIS bb's
 

Anybody ever tried them? (especially the heavier ones, such as 0.30 and 0.33) I'm looking for some ammo to feed my VSR.

I saw them used extensively in Japan, though I've never tried them personally. That doesn't tell you much... except that people DO use them so if they were pure crap I doubt people would...

As far as I can find their also the only ones to make multiple weights of green glow BB's.
