I traded my Maximas250's on AT for some other CX 200's and some CX200 3D Selects and the selects came with these nocks . I have looked on eBay and alot of archery cataloge's I have and cant seem to find them they are NOT the standard CX TCX nock. Does anyone have a clue ??? I kinda like them and want to purchase some more. A buddy told me they are the CXL 2 inline nocks but what I find on the internet dosent seem to match
