Aftermarker barrel need no "break in." As stated in the article by Gale McMillan, a barrel maker told buyers to break in their barrels and it boosted sales 10%. Thats like a tire company telling you to do a 3 second burn out to ensure your tires are round. Great way to sell more product. A lot of companies will void a warranty if anything is done to change the interior of the barrel (home lapping, fire lapping, final finish, etc.) And as stated above, benchrest shooters developed break in of sorts years ago when barrels we're complete due to old techniques of manufacturing. Also, nothing in the benchrest world should ever EVER be brought into the AR world. Those guys are dealing with 20+ pound guns that are worthless except for putting tiny holes in paper a long ways away. There are no moving parts. Everything is spotless, and match winning groups can be called to the 3rd and 4th decimal place. ARs need slop and can handle dirt just fine. No need for benchrest OCD. It'll just drive you crazt. In the days when CMM machines with ruby heads can measure parts to the millionths, top quality barrel makers give you a finished product. Just shoot it.
