I'm building a DeAR22 upper, and realized I had a spare barrel nut lying around. I'm very tempted to use it, but do y'all think there could be issues down the road with a metal nut on printed threads?
The small bit I know about material science makes me a bit afraid to do it given the hardness difference, but not smart enough to know if it's substantial enough to be a problem
