6 ea - of the Punisher Nock designed for the SA Sports Empire Bang Sticks 20" Carbon Crossbow Bolts (Basic Carbon #577, High Vis Yellow Camo #594, And Bulk 36 Pack Basic Carbon #593)
These are replacement nocks designed to convert the above mentioned bolts into Punisher Bolts. These nocks are appropriate for use on any SA Sports / Empire Crossbows, along with many other crossbows requiring a half moon nock.
The existing nocks on your bolts will need to be removed, and replaced with the Punisher Nocks using a "super type glue". When replacing the nocks the half moon MUST be aligned perpendicular to the odd colored index fletch which goes down in the track when seated on the crossbow. This will ensure proper string contact with the nock. (See Pictures)
