On newly chambered barrels I fire one round and clean and lube it. I do this each time for 10 rounds. Then I fire 25 rounds cleaning it after every 5 rounds. This will ensure that no burrs are left in the chamber or in the barrel that can cause copper to build up on imperfections.
I have a new ar 16in barrel chrome lined 1-9 twist. How do i break it in??????

ALWAYS clean from the chamber!
I have bore guides for every rifle I own and I NEVER clean from the muzzle!
Bore guides keep the solvents, oils, loose crud from getting into your reciever.
The time savings alone from not having to clean the crap twice (once out of the top end/barrel,
And again out of the lower end where it 'Drooled' when cleaning the top end)
Is worth the bore guide!
It's not as big a deal if you have one of those ONE PIECE polished stainless rods that don't take bites out of the muzzle crown,
But if you are using a sectioned rod, especially a STEEL section/break down rod,
Every joint will take a bite from the muzzle crown.
Every time I see the local 'SWAT' guys at the long range shoots, I have to giggle a little...
they ALWAYS use those old military cleaning rods in ill fitting sections, and they ALWAYS start from the muzzle!
That's just money the bank for us when they do that,
You KNOW they aren't going to shoot MOA groups with giant bites out of the muzzle crown,
So all I can say is, "Thanks For Donating To The Pot!" when I see them do that!
One other thing,
With an AR top end, you want to clean it with it sitting UPRIGHT.
If you turn it over, oil, solvent, crud gets into the gas system, never a good thing!
Always keep the gas tube/front sight facing 'Up' and that won't happen...
I don't say much when I see a SKS or AK being cleaned up side down,
There isn't any point in correcting them, those rifles are never going to shoot MOA anyway...
