Techt Paintball has put together this kit DM/PM o-ring kit for the bolt. The Techt DM bolt o-ring kit includes 1 of every o-ring you need to rebuild the ENTIRE bolt. This is a great starter o-ring kit so you can. Techt Recommends you have a spare bolt o-ring kit in your gear bag or toolbox because one blown out bolt o-ring will ruin your entire day of play. Most fields will not have this size spare o-rings laying around
NOTE: Bolt is NOT included.
