I don't understand, do your practice blades look like this? These are the ones that came with my KillZones. They just scree in like any other tip. Blessings.........Pastorjim
NAP stopped shipping full practice heads with the Killzones a few years ago. Now you get a single practice blade, the same as the one in the practice head, which you need to swap out into one of the broadheads in your package. I've done it a few times and aside from the nut being small and hard to work with found it fairly easy. Simply unscrew the nut from the bolt that holds the blade assembly in the ferrule, pull the bolt and the blade assembly out, slide the practice blade in, put your bolt back and in screw the nut on.
The field tip is more accurate than the practice heahead. Just test the actual heads if I want to know it flus like a tip
Thanks JZ. I bought 10 packages of Killzones on sale awhile back so I was unaware they have this kind of head for practice. I do like the old style as they shoot just like the real deal.
