Bolt help

[opterasis]

Okay, I was looking at this bolt... http://www.banditpaintball.com/customer/product.php?productid=44&cat=15&page=1 however, I don't know what the difference is between with and without O rings? And I'm assuming since I'm using CO2, I need the high pressure version.

get highpressure, color of your choice, and with o-rings. The o-rings will prevent blowback (into your hopper) ... it's a good thing ;)

As always, thanks for the quick reply :)
