Take a plastic wal-mart bag and cut about a 4" long piece and wrap it around the part of the nock that goes into the shaft. I had two of the Twenty Nockturnals I have that were a little loose. Fixed them right up....killed 3 this year with one of the ones I did that too. No problems at all.
I still love Lumenoks I have never had issues with them. They are extremely bright. I love red.. to me they seem the brightest among the rest. I know I have used tracer noks in the past and I know I wont go this route again.
I like Green & Red. I've tried them all but Firenocks and I'm not paying that much...lol. My Nockturnals are easy to mess with and have never let me down. I don't like the Lumenoks....Don't like how they activate. That is just me though. A lot like them.
