For me it was just swapping out my sight tape 3fps slower. I’ve used them in both .165 and .204. They shot the same left right for me. I tune with bareshaft before broadheads and use the lights during the whole process. After repeated use the nocks will loosen up a bit but they will warranty em no questions asked.

 

Sold mine on here awhile back, I liked the design but wasn't a fan. The actual nock would pull out of the sleeve fairly often when practicing so I never took them to the woods. Maybe it was just poor fit on my center serving since I sanded one down a bit and that helped but never fully remedied it.

 

Bought a pack a couple years ago.
Had two nocks break an ear off while shooting the first day. I was lucky my bow stayed together.
They went in the trash.

 

I don't use lighted nocks but I'm just happy in engage in conversation that doesn't have a question of contacting an air line. Lol

 

Well looks like I might just have to bite the bullet and get the FireKnocks for what I want out of them.
Just hate to spend that kind of money on knocks. Thanks for the input everyone.
