    Give it a good thorough cleaning right out of the box. Many manufacturers use cosmolene (sp) or other nasty shipping greases that like to gum up.

    Give it a good cleaning, plenty of good lube and use quality ammo to establish proper function.

    Haha. I like John's videos. Noveske does warn on their stainless steel barrels to not "Shoot your barrel hot enough to brand cattle!"

    I generally agree with the above video and this one: https://www.youtube.com/watch?v=TRRahHX9Zkg

    However, I will say that when I got my LPR I did a little research and ran across a break in procedure on Krieger's website: http://www.kriegerbarrels.com/Break_...246-wp2558.htm

    Stainless:
    5-10 one-shot cycles
    1 three-shot cycle
    1 five-shot cycle

    I figured it couldn't hurt anything... So, I brought my Boresnake to the range with me and ran it down the barrel according to their suggestions. Then I ran through about 6 more mags to make sure the barrel was good and broken-in.

    Oh, geez.

    A lot of AR's do go through a "break-in" period. This is true, although a lot of people will try and tell you otherwise.

    You don't need to mess around with lubing your barrel and all of this other silly crap.

    I recommend that you try your best to shoot nothing but full power 5.56 such as M855/M193 for your first 500 - 1,000 rounds. This will wear everything right into place. So, lube the shit out of your entire BCG (dripping wet) and run your weapon as hard as you'd like.

    Depending on the gas system, gas port size, etc you may run into short stroking issues with low power .223 such as PMC or Wolf for the first 1,000 rounds or so. If you're running something like a 16" mid-length then you want to run a standard carbine buffer for the first 1,000 - 2,000 rounds also. After a couple thousand rounds you'll want to switch to a heavier buffer.


    Don't bother with all this "shoot a round then boresnake and lube your barrel" crap. That's total BS. The AR15 platform has very tight tolerances and thus a few things do need to "break in" such as the BCG and also the gas port smoothing out/opening up . This happens naturally over the first 1,000+ rounds fired through the weapon; typically faster if you're shooting full power 5.56 ammunition. Anything else is complete and utter bullshit.
