Precision machine turned from self-lubricating delrin plastic. Lightweight, yet strong and extremely durable. An external o-ring to help seal and minimize blow back. But more importantly an internal o-ring to seal against the Power Tube. Allowing for a more consistent acceleration of the paintball. The Tippmann bolt and valve that comes standard in your marker is already a very efficient design. That's why most other aftermarket bolts don't do anything to improve the gun! The best, most cost effective way we've found to make it BETTER was to add the internal o-ring. Something nobody else has done..... Yet... Gas efficiency went up noticeably, not a huge leap, but we're happy. More importantly our testing showed a significantly tighter chrono grouping!

The bolt gained a plus / minus figure of 6 Feet per second over stock! This is the best 20 bucks you'll ever spend on your Tippmann. Our bolt fits both the Model 98 and the A5.
