Buy a case of ammo and a handful of magazines.
Keep the bolt carrier well lubed, and shoot.

Assuming it's just a combat carbine, and not some fancy precision match-grade AR, follow instructions in Posts #2 & #3.

make sure the bore is clear of packing grease or excessive oil and shoot the hell out of it. the only part of the AR I have seen with out a doubt settle in with more shooting is the trigger.

I do recommend giving it a good cleaning, and lubing heavily before the first range trip.
I'd suggest starting with a single round in the mag, then a 2 round mag then a three, before you slap in a 30 and discover it runs away. also lets you check your Bolt Hold Open.
Good quality, brass cased, full power 5.56NATO is a good idea for the first 200-300 rounds, as is more than one magazine. If it doesn't function, these two items will eliminate the most common causes of malfunction.

Yeah, remove any excess preservative or grease, shoot it until your finger is tired.
And make sure the patch is headed down the bore before the bullet has exited.
Seriously, I agree with what has been posted but will add to not let the barrel get too hot. But that is standard advice to prevent shooting out a barrel prematurely.
I clean my new barrels a little more frequently than after it has some rounds put through. Probably not necessary but makes me feel better.

If it's chrome lined, then don't worry about it.
Barrel 'break-in' is only helpful with non chrome-lined barrels.

There is no snake oil formula you can follow to make the barrel more accurate or season it that hasn't been done at the factory. Peens, microscopic imperfections, fissures: None of this can be remedied by how often you swab a barrel in its infancy.

Well, Noveske uses barrels that are way over spec for their purpose, cut from SAW blanks and double chrome-lined.

If they indeed use "SAW blanks" for AR barrels, then by definition they aren't mil spec.
Who said anything about them being milspec?
I think this topic touches 2 subjects; barrel break in and rifle component break in. For both I defer to the 1st response, followed by a good breakdown, scrubbing and application of quality lube.

Please reread post 13, it answers your question.
SAW barrels are 4140, not to specification for M4 barrels which are required to be constructed from 4150 CMV. Therefore, SAW barrels are not "over spec" as stated in post #13, nor are those made by Noveske if they indeed use SAW blanks. By definition, for the barrel to be "in spec" it would be 4150 with the presence of vanadium.
As stated, post #13.

Only if you can show that the difference makes them inferior for their purpose.

I 'LAP' all of my new rifle barrels.
Why? Because my daddy expected me to do it, 50 years ago. So, I just do it.
Does it do any good? I honestly don't know, it could but most likely has little effect.
I have and will continue to 'lap' my new barrels. The only rifle barrel I didn't 'lap' was chrome lined. Come to think of it, that's the only chrome lined barrel I have ever bought new.
EDIT:
This does not include black powder rifles.

Since you said please.
I see no mention of "mil", only that the poster claims that Noveske's barrels are engineered more than a typical AR. Noveske's main claim is the hammer forging process and extra thick chrome layer. They are not however cut from 249 stock, just made similarly. http://noveskerifleworks.com/cgi-bin/imcart/display.cgi?cat=106
Not sure what rifle the OP has, but trying to stay okn topic, Noveske does not have a recommended break in and says there is no benefit to one

Splitting hairs. Let us assume that the term "spec" used in a discussion about the AR15 is short hand for military specification, which it more often than not is. You know that, I know that. "Mil", while not used, is implied when "over spec" is.Since you said please.

In which case, Noveske's forging process is within spec, lining process exceeds spec, but unless the barrel steel is 4150 CMV then the barrel is not "spec", over spec, or even mil spec with implied or stated semantics. We can agree to disagree.
Just shoot it.

Apparently you're the one who wants to keep beating it to death.

Not beating anything. Some folks like accurate info, or "better than half-truth".

I only feel the need to "season" stainless steel barrels
Fire one shot, swab bore.
Fire three successive shots, swab bore.
Fire 6 & clean, fire 9 and thoroughly clean.
Done.
Chrome moly and chrome lined will not have any major positive results from such treatment.
Stainless steel will smooth out and become much easier and faster to clean.
Does it make the barrel more accurate?
Maybe, maybe not. You decide.
