I had heard all the stories about the gorilla that installs the PSA barrels. My son wanted to replace his SS barrel on his creedmor, I warned him 9f just such a situation.
New barrel arrives, got all psyched out, grabbed the rachet and barrel nut wrench and went to town.
Came right off, no fuss, no muss. I felt cheated, and my son had that look of 'why the lecture for nothing?'
