I read the barrel break-in guide that is posted in the do-it-yourself forum. The article didn't mention the use of a brush through the barrel only a patch. If I use a boresnake between the first several shots would that dammage the barrel in any way? Do any of the AR15 veterans here use a boresnake as their main method of cleaning?

Barrel break in is kind of a myth. Some practice it and some don't. I never "broke" in a new barrel and my AR's will shoot less then inch groups at 100 yards.

I say just shoot it!

Bore snakes work ok but do ZERO to remove metal fouling lie copper and lead pressed into the poors of the steel. Use a good bronz/nylon brush with copper solvent, a good rod and a tight jag and that will clean it up like a mirror! Have fun!

I don't really break in my barrels, but for chrome lined barrels, I believe you are supposed to just shoot the things for at least 100 rounds before you clean. Something about smoothing the chrome or something.

I don't own any non-chromed AR's so I'm not sure about those.

Barrel break in is not really to break in the barrel rifling but rather to break in the throat area where the barrel was chambered. There is a sharp edge where the reamer stopped cutting that will remove quite a bit of jacketing at first. That removed material will be in a plasma form under the high heat and pressure and will be deposited in large amounts until this area is "broke in". It is not necessary, but if you are looking for the best accuracy and barrel longivity that your barrel can provide you, then break in is not a bad idea.

Barrel breakin is horseshit! These are not bench rest rifles and there were very accurate rifles long before any such nonsense was thought of.

An AR is meant to be shot, not babied.

Shoot that shit, but what do I know... I've only got around 250 rounds through my first AR!

Shit, I just noticed that I surpassed 100 posts JJ, who gives a shit anyway!

Break in is for non chrome lined match bbls. If you have a chrome lined bore just shoot the hell out of it and clean it when you get home. Thats all the break in you need. Non chrome I would say put 100rds or so through it then clean it.

There is an excelent article HERE

In it, a couple barrel makers say that barrel break in is a myth.
They also say that they put paperwork in with their barrels that recommend break in (cleaning OFTEN for the first 100 rounds). They do this because is wears the barrel faster, and increases their buisness accordingly.

Aslo, on Chrome lined barrels its recomended to shoot 200 rounds before cleaning.
