I think you will only need the broadhead rings if you are using expandables that that fold all the way back to the insert on normal arrows ! Since the Axis don't have the insert on the end of the shaft....the blades would potentially crak the shaft when they open !

I use Spitfires and the blades open to the back of the ferrule and don't hit the shaft.......so I'm not using the rings !

Did that make any sense [8D] ???

I have one bad nock......haven't heard of any other problems !
