    Hey guys,

    So the last few seasons, I have shot the GT Nockturnal nocks. An issue I tend to find with them is when I'm coming to a full draw, the nock tends to pop off my string which is a pretty dangerous situation IF I were to punch the trigger from my release. Other issues, I have is sometimes I have to click the nock on my string which causes my light to come on.... Do I have a string diamater issue or do others see this particular problem?

    I can’t say that I ever had them pop off the string but I have had them come on when I mock the arrow. Something else I noticed is that they were a little loose in my arrow. They actually flew off when the arrow hit the target. To remedy that I wrapped nock with Teflon tape to make it fit more snuggly. The only reason I’m not switching to lumenock is because I already have 5 of these and they are to expensive to just not use them. Just going to deal with it for now.

    Nick pinch is my suspicion. What is the ATA and draw length on your bow? Are you running nock sets inside your D-loop?

    If its popping off I agree with Planopurist sounds like nock pinch. Any chance you can post a pic of your nocking point at rest and maybe at full draw?

    I use plastic food wrap, like Saran Wrap, and just use the nock to press it into the arrow. Just rip off the excess. It’s probably cheaper than Teflon tape.

    Just sand the inside of the nock till it des not pinch, don't take too much off but it works well, sand both sides evenly.

    Mine rattle. I’m probably not going to use them. I notice it most in arrow flight.

    That’s not the type of “nock pinch” I’m speaking of. Nock pinch is when the string pinches the top and bottom of the nock while at full draw. This is usually seen with really sharp string angles (like this seen on short ata bows) and/or long draw lengths.

    Tying nock sets inside the d-loop will help to spread out the Loop’s ends and make the part of the string a little flatter in the section that the nock clips on. Spacing one nock set a couple of mm from the nock will give the nock a little “breathing” room.

    IMO, sanding the inside of a nock would make the nock fit looser on the string and create another variable which affects consistency from arrow-to-arrow.

    I have had issues with it being tight and the nock lighting up when you put it on the string, my bad.

    Don't sand the nock down...........

    Your nock points are likely too close and a very tight fit on the nock. When you draw, they get even closer because of the string angle at full draw......which is popping the arrow off because it's too tight. Aside from this issue, you'll get weird and inconsistent arrow flight as well. If you know how to tie nock sets retie them and give yourself a bit of wiggle room. If not, bring to your local dealer and ask them for help with this, it's a quick 5 minute fix.

    I get what you are talking about but mass produced plastic will not fit perfectly.

    I forgot to mention that I've had them loose before too. I took a dab of superglue to fix that problem.

    No d-loop. ATA- 36" and draw length is 31.5 at max draw on my bow.

    I'll try for this after I get back on my vacation in a week in a half. See if maybe you guys can see something.

    With that draw length and no D-loop, nock pinch can still be an issue. I would say still try a d-loop and nock sets.

    not using a D-loop? I promise you it's nock pinch. Before D-loops were popular; I used to have it all the time. Cost me more than one deer. I then got a Gator Jaw release and that solved it although it was tough on the serving. This was back in...maybe 93? I had an overdraw on that bow I remember that.

    I still have it if you're dead set against a D-loop for whatever reason. If you're interested.

    Question, if I don't go to a D-loop, do you think the problem would exist if I went with another brand manufacturer of lighted nock?

    It just depends on how large the back end of the nock is.
