Kingman EM1 - Vapor Valve, Sonic Ball Detent, Sonic ASA adapter, Mac Dev Gladiator, TKO Drop, PE 68/3000, All American Teardrop 12", CP 14" .685, Swancreek N-bolt
Medium to large bore barrels. My All American is .700 and it fits flawlessly. My .685 CP will not work at all. They also work very well in J&J Ceramic 14".
They're inexpensive - less than $50. They are a good quality paintball, too.
Good fills and are visible. Kewl colors, too. I have some black ones and some that are dual tone. I use the dual colored ones as tracers. ha ha ha
May not always break at long distances, but I've never had a problem at 80 feet or less. The black ones are hard to see. Not always available in local stores.
This is a quality ball for those who don't have the $$ to spend on Marbz. Save your money - these are more than worth it.... The guys from my local shop will use these almost exclusively. JT Maxims are nice, too and if you can find them on sale I say consider them, too. Marbz are good also, but the powerball never lets me down.
