My friend NiborDude and I finished two 90 balloon k-mods. Nibor has tested his gun twice, twice a pre-existing stress crack has blown out. I tried mine once and I need to adjust the trigger valve. Hopefully they will be working properly tomarrow so I can get some stats. Pics will follow as well.
We gave the guns the name 210K [210000 is too long] because the power makes an ordinary 21K feel weak.
