I just completed one of my AR-15 builds this afternoon, and I was out shooting with my buddy in the back yard. I always clean ANY rifle I have that I have never fired before even if it is new ... prior to shooting it the first time.

He started ranting about how I should break it in, or else. I told him I NEVER break in my rifles, and they have all shot fine without any issues.


What are you opinions?

Break in or NO break in?

Chrome lined, Stainless, or CM?

Never mind... I don't break in my BBl's either.

Lots of differing opinions on this one. I'm going to sit back and enjoy the discussion. I enjoy watching a dead horse get beaten.......:p

If you're having trouble with metal fouling in a particular rifle and tend to shoot a large number of rounds at a shooting session with it then a formal break-in might show you benefits in that gun. There are other solutions that will work as well and that would probably be faster and easier, but that's one way to do it.

If you're not having metal fouling issues then it's a total non-issue in my opinion.

If you're still worried then just clean the barrel thoroughly--removing ALL metal fouling--after each shooting session and you'll achieve exactly the same result, albeit more slowly.

It's a chrome moly barrel.

Break in or NO break in?
Who cares about opinions? What does the manufacturer say? Answering this probably involves reading the owner's manual . . .

If it is poorly machined with tool marks throughout, no "break in" process will fix it.

Shoot it normally and clean it well at the end of the day.

Some of the makers of very fine barrels recommend a break in proceedure,and they describe t for you.I have read Gale McMillan's advise on the topic,and won't argue.

If you are working on the tailgate of a pickup,balancing the rifle on your knees without a bore guide ,etc,could be you will be doing more harm than good.

I compromized and pulled a new bore snake through a couple of times with a little "PatchOut" on the leading end.I did this between each shot for the first 10, then between each of the next few groups.
Did I do any good? I do not know.I felt better.

I think if it makes you feel good do it, if not dont worry about it!
