Arrow Nock X/5.2mm LED Nock Screwdriver Included, 6 PCS Universal Fit for Arrows with ID of .204".233".244" & .246"

My husband has bought so many various kinds and this is exceeded all expectations. The price is great, the red is incredibly bright, and they are easy to install. Recommended to a friend and she bought all 4 colors.

Will buy again for they work as good and last as long if not longer than luminox

My husband has been wanting luminocks for so long! I got these because they look super bright and I loved the colors. I didn’t ask him about them and just got them hoping to surprise him as they say UNIVERSAL fit. But they are not universal fit. They don’t fit mine or my husbands arrows. They do fit my sons so we will be keeping and using them as they are super nice. But just be careful when buying, if you see universal fit make sure you look at the letters and verify they have your arrow letter on them or they may not actually fit. Be careful because universal fit isn’t actually universal fit.

Got these to try out with my 5mm Victory rip tko's, they have a good snug fit and seem to be pretty durable. They all worked with no issues and appear to be pretty bright. So far I'd highly recommend. Also every nock weighed 20 grains on the dot.

Very bright and easy to see. I like that the colors change making them easier to find. Great product. Bought 12 and they all worked well!

Gift to husband, he loves them, so much easier to find our arrows

Not sure how this gets so many good reviews. Within a few shots one of the nocks broke in half (pic attached) sending my arrow down range in a wild spiral. Began checking all others and every one of them has already developed cracks in the orange insert that holds the mock. nocks are barely held in now and slip out with minimal effort. And to answer the question, yes I used the correct size adapter. Do NOT buy, they are poorly made and dangerous, not worth the savings.

So far so good. Fitment system is very helpful. Match up your arrow size, and wah- lah!
