Best lighted nock on the market
When searching for a good nock for micro diameter shafts you aren't left with many options. And when I buy equipment I want to buy something that will last years. And these nocks will last a lifetime if you don't smash or lose them, best lighted nocks on the market period hands down. Change out batteries any time quick and easy, end cap system is genius and simple to install. The whole firenock system is in my opinion lightyears ahead of all other options available. Run them not only on my hunting arrows but also on my target setup as well. Dorge from firenock is also great with customer service, more than happy to help with troubleshooting any issues you may have.

Hunting Circuits G
Amazing system, the LED's are SO bright, and with the pulse width modulation control the battery life is orders of magnitude better than others. It's also really nice to pair it with a quality nock, as most lighted nocks really struggle in the actual precision of the nock themselves. Switching everything over to Firenocks now.
