I have a couple of these kick'n around. The thing I like about them is they don't snap on , just a nice snug fit. Any ideas on the make ? It is greatly appreciated

THANKS,

maybe Nirk locator knocks?  I had similar ones on some vintage cedar arrows by Bear.

That's a Mercury Index Nock.  Great nock until they changed owners or something and quality went down the tubes.  You can still find some floating around, just look them over pretty good.  Most of us went to Bohning Classics and haven't looked back.

Thanks Tim, I picked them up about 8 yrs ago. Anybody else ?

Can I take back my answer, I agree with Fletcher.

Fletcher,
THANK YOU      

Fletcher is correct.  That's a Mercury index nock.  Like Fletcher said, they were great until the quality control went down the tubes then you got as many bad as good and it just wasn't worth it anymore.

May I ask why Bohning Classics , better Quality ? And are they a snap on nock.

THANKS  

The Classics are not snap-on tools (  :D  ), and the things that determine quality are the plastic used and the accuracy of the mold. I am guessing that some plastics mold better than others, and for sure some hold up better than others. I have had old nocks break, resulting in an "oh spit!" at the firing line as the bow dry-fires and the arrow goes astray. And some of the newer nocks just plain  sounded  brittle, right out of the bag. It was the type of plastic they used, the nocks tinkling when shaken rather than thudding dully against each other.

The "bad" Merc nocks will have uneven edges around the mouth and prominent mold lines lengthwise. They are useable, but that is about it. I love Merc nocks, and have a lot of them, but the non-snap-on Bohnings are very nice indeed. Sleek.

I still like my stinky old Arizona nocks Killy.....the plastic is flexable and pretty darn durable........Kirk

Killy,
Thank You
