Hey guys, I've assembled multiple lowers but this is my first upper I've put together. I'm having an issue with my barrel - the OD is 1.054" while the ID of my barrel nut is 1.015"... I'm afraid if I ream out the barrel nut that there will not be enough meat for it to hold on to the barrel. Any suggestions?
That did it! Wouldn't have thought they were any different, but the ID was 1.061". Thanks for the help!
