Custom built spyder with Bob long Millenium Body, Cyclone bolt, pMI reg, PMI nitro, J&J ceramic barrel, Booyaah elcd rev 3.1
Superfast, very reliable easy to install, all the tourney players at the fields will be jealous that you can out shoot an angel with a $350 marker.
$200, no mechanical safety
The absolute best upgrade for you marker if you feel outgunned or just want to spend some $$$. I have shot my spyder clone side by side to tourney markers (cockers, shockers, angels) and this gun is just at accurate and shoots quicker.
