Hell of a time getting it in...

[FyreFighter]

Just installed a barrel into an Aero upper and damn was it is a tight fit. Everything was lubed and I still needed a rubber mallet to get it started. Had to resort to a hammer and block to get the barrel seated, and used the barrel nut to finish the job and drive it home. I don't plan on ever rebarreling the upper but will this potentially cause issues in the future?

That shouldnt cause an issue at all. All my Aero builds were tight and functioned very well

Reading your thread title, the only thing I can think of is, "that's what she said"..
