KILLER INSTINCT ARC NOCK - Moon nock for SWAT XP - Pack of 12
The ARC Nock is specifically designed and engineered to be compatible with the Killer Instinct SWAT XP Crossbow (Model 1020). This is the only nock acceptable to shoot from the SWAT XP, do not attempt to use any other shape or form of nock. Install the nock on a 22" bolt greater than 400 grains and make sure the ARC nock is glued in at a position that the un rounded edges line up vertically with the odd color vane and that the end of the vanes are at no less of a distance than 1 3/8" to the start of the nock.
