New AR15, Best ammo for "break in"

[Texas42]

A little fouling often improves accuracy. improper cleaning damages barrels.

Your barrel is a 1.5moa-ish barrel. Mil-surp ammo often isn't anywhere near that.

So the article that was posted says to fire one shot then clean for about 25 rounds? Do I need to do a full cleaning or just run some cleaner through the barrel with a swab? As states, I'm new to this stuff so please go easy on me lol

Its whatever you want to use. I tend to do .223 pressured brass first then steel 223 or 5.56 pressured brass.
