Always staying ahead of the game. Be the first to have PURE TEFLON bolt in your marker. If you have heard of it you know it is impreganted to about every known substance for near frictionless surface and anti-stick surface.
Signature series comes in 2 forms. My proven high-flow standard angled intake, single hole exhaust. And....I also have modified a new design released by some competition. I have a venturi style that is similar to the Planet Eclipse D.A.R.T. Bolt. Here is the info they put out.
Players are constantly looking to shoot more fragile paint. The D.A.R.T. (Dynamic Air Release Technology) Bolt has been designed to help achieve just that. The protruding Diffuser head of this new bolt offers up a cushion of air that strikes the ball across a much larger surface area. By distributing the air blast over this larger area, localized concentrations of force on the ball are greatly reduced, and hence the likelihood of an in-barrel denotation. Not only that, but the protrusion of the bolt face also helps to hold the ball centrally in the feed, not allowing it to role aft. This prevents the partial incursion of a second ball into the breach while using the type of force-fed loaders preferred by the majority of players. This helps prevent clipped or crushed paint falling into the breach.
The Spudnuk'l Teflon Wrath Bolt is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
