I'm pretty disgusted with these Meta nocks that I have on these nano's cause they get messed up pretty fast..and getting a broken one out is a pain in the arse. Hubby had to drill a hole in the last one and now I got another one today which might have to have same treatment. Question is I know I have to get the pins for the nanos but can I use any brand nock part that fits on pins? I think I remember reading that all nocks that go on pins are pretty much standard. I need to order some stuff asap and change these meta nocks asap.
