A unique combination of soft and hard elements, this bolt runs smoothly on two o-rings with the added security of a Delrin front end. The rear of the bolt is drilled in all four directions to allow the use of the vertical pull pin. The super high flow and smooth action of the Yin-Yang bolt help to reduce the overall pressure of the Sonic Cocker.

quiet, vertical bolt pin is uber cool, doesnt chop
Weaknesses:
none i can think of
Review:
I've used this bolt for around 3 months now, and out of 3 cases of paint, have only chopped 2 times, using a Dye Swing. This Bolt Rules,Delrin front rules,looks good
little choppage,very smooth, overall, very good. I like this bolt very much, but actually, I'd put my money with a ST Supafly, but the ying yang is an awesome second choice
Conclusion:
BUY THIS BOLT, but if you don't want to, but a ST Supafly, my $.02 worth
Evo-X bolt (about the same bolt wont run as low pressure but its ventri)
Marker Setup:
2k2 MacDev Sonic Cocker
PMI 68ci 4500psi air tank
DuckBill ASA
Gladiator Regular
12vt Revilation w/x-board
Strengths:
Nice and light exelent for LOW pressure cockers (such as my sonic) very smooth. One side of the bolt (were the air comes through) its somewhat flatened (i think but it works this way) incase of a misload the Ultra low cocking pressure wont chop it, it just stops!
Weaknesses:
I think for a bolt that costs this much the could have at least added some ventri front to it but it still works amazing!
Conclusion:
Great bolt if you cant decide to get a Besales or this get this its the best out there not even sure if it could work any better with ventri!!!!!!!!!!!!!
