By changing the arrow nock to the new QuickFire Mag Nock the Chief AJ HFX will now shoot either full length arrows or steel balls with out changing the pouch. Simply shoot an arrow at the target, fold the flipper down and shoot a steel ball or vice versa. Now go into the field knowing you are carrying arrows for large game and steel balls for small game that both shoot with the same effiency that make the Chief AJ superior to all other hunting and survival slingshots. Comes with 3 - QuickFire Mag Nocks to a pack. Does not damage arrow and to go back to using the arrow for standard bow hunting just swap the nocks back.
