This is one item that every paintball player needs to carry spares of! These high quality urethane O-rings work on all CO2 and HPA tanks. They also work on many styles of marker bolts as well. If your o-ring goes (and eventually they all will) and you don't have a spare then your day of playing paintball is over!
