Best Lighted Nocks | Nockturnal Universal Fit Lighted Nocks | Farming For Whitetails 

These come with bushings that should fit any arrow … maybe almost any arrow. It looks like in Nockturnals, it would be the G size that would fit a 4 mm arrow shaft. Hope that helps!

@@farmingforwhitetails it doesn’t have a bushing for 4mm arrows and the nock itself is too big and the nock doesn’t even fit the bushing tight enough. I have some of them

Darn! I shoot Goldtip Kinetics which are .204 diameter shafts, and the nock by itself with no bushing fits those.

@@farmingforwhitetails that’s because that’s a 5mm arrow. 4mm is .166

Right, was just sharing what I use. Thanks for watching and commenting!
