anybody have any time with a treated barrel/bcg? just bought one from a kid and am wondering what to expect. seems accurate and cleans easy.
velocities are the same from one ar to another with the same ammo so that isn't affected.

does the chamber look bright? Some manufactures talk about the treatment and say it prevents corrosion and then some polish the chamber so that it looks like bare steel. I guess it works ok, it takes a chrome barrel about 1000 rounds to iron the wrinkles out of it and start shooting a bit better.

chamber, bore and BCG all as black as hitlerlly's heart.
shows no brass rub like the ejection bump does. ran 30 rounds through it and swabbed it with a patch with butches bore bright (SP) and the next patch was clean. think that works for me as i detest cleaning a AR. must be a hold over from the 60's. i think i can get this setup clean with a few squirts of brakecleen or such.Nirvana!

If it shot well, I'd thank the Lord and call it a day.

If the quality of the barrels are the same a Melonite treated barrel is usually more accurate than a chrome lined and last longer than stainless. They are normally around 60c(case hard) hardness where a stainless is around 30.

thanking the Lord and calling it a day!
fifty rounds spent and 42 squirrels gone.

A new PTG reamer has had difficulty even marking it....
