Does anyone have an idea on what size lighted nock to use on black eagle carnivore arrows? I have used nocturnal before and had great experience with them but open to any other suggestions!
Correct - it's a standard S nock (0.246). If you haven't looked into the Lumenok HD Orange I would. They are by far the brightest nocks I've ever used. You can darn near use it to light your way to your stand if you needed to.
