    Everything firenock makes is highly engineered and the price reflects it. This lighted nock system works and is probably the best around, and I’ve done a lot of research and trials. However, you will mess some up installing the shock end caps as there is a definite learning curve. The only other down side is they are very snug on the center serving, I mean VERY snug. I have a VXR with stock zebra strings and I assume the center serving is .021. Every other nock whether brand stock (Easton, black eagle, etc.) or after market (beiter) fits as you would expect. It’s snug enough that your bow shop will notice and it will make two flat edges on your serving after a while. Might even mess up your tune. FIrenock: Please note that all Firenock vertical bow nock are to be fit serving size of 0.110" to 0.125" as stated on all our literature. Please make sure you check your serving size for fit.
