proper way for breaking in an AR-15
Is there a proper way to break in an AR? I just picked up a custom build from my gun shop that the owner made for a gun show and I would like to find out how to break it in, and make sure that there is not some way for me to jack up the barrel.
If it makes a difference, it is a JP Cryo treated stainless supermatch barrel...
also, I believe that it is chambered in .223 so this means i cannot use 5.56 correct?
