How many sweat round counts on ARs? namely 5.56.
With bolt guns and "accurate/precision" gas guns (not battle rifles), I get wanting to be concerned about round count and barrel life. But, on a duty/battle/competition type rifle? In my previous life we'd change barrels or uppers around 20k+ rounds. Probably closer to 25K-30K.
I have a couple barrels I slapped on guns that have about 11k-12k on them. They pass a straightness gauge and TE at ~3. Rifling is fine and they are still within the 2.5cm at 25M Army requirement (<4MOA) and they headspace fine.
Just mostly wondering because some people FTFO over 1000 rounds on a gun (any gun) and would you keep a 10k round barrel or replace it? And why would you replace it if there's nothing wrong with it?
