Most quality, modern production AR's are plenty accurate for a fighting gun. The accuracy of these guns are generally only reduced by the accuracy potential of the ammo we feed them. Example, if we feed the rifle quality ammo such as say Hornady TAP we get better accuracy than say Wolf.

With that said, I have been looking into quality barrels and how that accuracy can be improved and still have a hard use barrel but still keep it as accurate as possible.

I found these two items below, very interesting. The first being the difference in SS barrels and how factory vs quality after market barrels differ. The second from one of our members on a S&W production AR barrel.

I'm interested in the difference in cut, button and cold hammer forged barrels and the end product companies put out.

Does anyone have borescope pictures of these three type of barrels? I can find pictures of the rifling of cut and button rifled barrels on the web but have not been able to locate pictures of a CHF barrel.

I'm not interested in a brand argument here just facts on barrel construction and the difference in cut, button and CHF barrels and the tooling marks and chatter left in the bore (or lack)

Thanks in advance,
