The Arc Nock was specially developed for the Killer Instinct SWAT XP crossbow. It is important to note that the SWAT XP may only be used with this special nock.
Use the Arc Nock with 22″ bolts weighing more than 400 grains. Make sure that the arc nock is glued on so that the non-rounded edges are vertically aligned with the cock vane. In addition, the end point of the vane should be at least 1 3/8″ (approx. 3.5cm) away from the nock.
