How clean does a rifle barrel need to be now that we no longer use corrosive primers?? Is a simple patch swab good enough? Why scrub it spotless only to turn around and have to fire fouling shots?


During my military days our M-16 barrels had to be spotless mirror shiny or the Armour would send you back to the clean table. Armors were fearful they would have to clean the whole weapon.

Keeping the upper and lower receiver as well as the bolt clean was clearly very important. But trying to scrub out copper from the rifling?/

I now believe we did more damage to the crowns trying to clean the barrels than any amount of fouling we were removed would have harmed them.
