Hawk....I told ya he said they were all a pain in the a$$.    

Shot one thru a doe on Oct. 1. The fletched end of the arrow remained in the deer and the broadhead was buried in a root. The arrow was in 4 pieces but the Nockturnal nock glowed bright orange. I did break the first one i put in an Axis shaft as the fit was tight and tried to force it  with the Axis nock installer which didn't fit the nock. I have since learned to use an emory board to get a better fit. Nockturnal said they would replace the broken nock. I found that with a 10 strand 8125 string and .019 serving the nocks are a perfect fit but are a tad tighter than the regular X nocks. Another detail...in daylight the green ones don't show up too well but are great in dim light. Orange, red, or pink seem best in daylight conditions.

Not to hijack this thread but have you all noticed any difference in tune with the heavier lighted knocks ?

If you're comparing them to regular nocks then absolutely they affect tune. More weight in the back of the arrow means stiffer dynamic spine (as opposed to more weight in the front decreasing dynamic spine).

Just weight my normal AAE nocks 14gr.,Nocturnal's 20gr.

6gr.WILL NOT  affect tune unless your a sniper shooting a thousand yards.

I have used my Nockturnal alot in the past months and all worked well,making hog tracking much easier and more sure of arrows placement.
Just one broke because a death 220# boar rolled over.For me they worth their price in gold.
