ditto. this whole "shoot x rounds and clean then shoot x rounds and clean" is a bunch of CRAP. |

I just ran a little over 500 rounds through my Bushy M4A3 on the first outing and cleaned and inspected afterward. There was very little wear and everything is working fine.
Just shoot it! |

Follow the manufacturers recommendations. Clean the bore first. Then shoot it.

After 2 to 3000 rounds it will be nice and smoothe and not so tight.

Some say that it depends on whether you have the chrome-lined bore or not. My buddy and I went and bought our AR's at the same time 3 years ago. I bought the last Bushmaster 20" A2 they had that day. So he got an Eagle Arms 20" A2. So in the cold, snowy weather that afternoon, I proceeded to "break-in" my Bushy by shooting several hundred rounds through it. He shoot a few and then ran a cleaning rod through it with cold hands. I was DANG happy I bought the gun with the chrome-lined bore that day. In fact, if I recall correctly, it was recommended that you NOT clean the barrel until after at least several hundred rounds (500?) for proper break-in. Can't beat that...

he asked my preferred method. i don't always go through the entire thing, just until i get reduced fouling. Krieger barrels break in procedure i also recheck my door locks three times, go out to the car and then return to recheck the door three more times. halfway to my destination i return home to see if the iron's off, i don't own an iron. |

All of my previous and current 9 ARs are chrome lined, none are match barrels.
Clean and lube, 10 complete strokes with the brush. Shoot and repeat cleaning after shooting until 600 to 1,000 rounds. |

Take it to the range and put as many rounds as you have through the barrel.
Take home. Clean. Repeat as needed. Enjoy. |

I take the upper to my friend house that has a registered lower, and then do 30 round mag dumps until I am confident all is well.

Bad idea if your neighbor is crazier than you and/or owns more guns than you! Case and point... I used to live next door to an ex MP and I saw them move four (yes count them FOUR) gun safes out of his 1100 square foot townhouse AND about 20 rifle bags, that appeared to have guns in them, when he moved out. That was you, wasn't it? hock.gif |

From what I've heard... if you bump-fire it underwater in a nearby body of water, that's the best way to keep it lubricated it's first few rounds.
ETA:  I wouldn't want anyone listening to my "advice".

Here's what Bushmaster has to say about the subject.
"What is the proper "break-in" procedure for a chrome lined AR barrel? After firing a couple hundred rounds, the chrome lining will "polish out" from its light, flat gray, factory-new look to a brightly reflective, polished appearance. During this break-in period, excessive cleaning with solvent or brush should be avoided as that will only prolong the time (and number of rounds) it takes to achieve the final "bullet polishing" of the barrel." This is for their chrome lined barrels. The all steel barrels have different advice. |

ok guys-i just recently picked up a Colt 6721 LEO marked AR-its my first AR. Havn't shot it yet.
This is a a stupid question but is the HBAR 1-9 16.1 barrel chromed on the 6721? Some say the earlier ones weren't-how can i tell if mine is a ealier one-can i just look down the barrel and tell? |
|

[#33]
if you have one with the LEO mark you have a newer model and the bore and chamber are chromed. now go shoot the hell out of it.
|

[#34]
at the very least it will have a chromed chamber
the arrow points to what you should see from the rear  there should be a corresponding silver ring around the crown if the bore is chromed. if there is any question about it being chromed degrease the area and dab some cold blue onto the suspect area. chrome does not blue. |

The guys are right - clean it to get any latent manufacturing junk out of there and then use it, no big deal. Here's what Bushmaster says:
After firing a couple hundred rounds, the chrome lining will "polish out" from its light, flat gray, factory-new look to a brightly reflective, polished appearance. During this break-in period, excessive cleaning with solvent or brush should be avoided as that will only prolong the time (and number of rounds) it takes to achieve the final "bullet polishing" of the barrel. I would suggest a reasonable quality ammo though, at least for the first 1000 rounds or so. Wolf uses cheap and therefore pretty dirty powder. ETA: Man it takes me a long to to type - same thing bobafett126 (and others) already said too. |

I just reread Derrik Martin's book on building match ARs and he essentially said the same thing. Zedker on the other hand advises THIS PROCEDURE for match barrels. (75K PDF file) |

To break it in, drop complete rifle from 6 feet (or, 6 meters for you non-USA folks) onto some jagged rocks. This will get those first scratches "under your belt".

I had a Bushmaster custom built long ago with a 24" chrome lined hbar. As pointed out, they said not to touch it with a brush as that will do nothing but slow down the "polishing" of the chrome lining. They ALSO told me to use higher velocity ammunition. I stated I was using XM193 and they said that would be great. All that said, I think I cleaned it once after a couple hundred rounds, and maybe fully cleaned it after 500.
I'm quite anal about the care of my firearms, and it's in my nature to give into the barrel break-in voodoo. But given the people I've asked who really know firearms, I figure it's a lot of hype. Gundraw |

Got a new NM A2 with SS barrel from Rock River. They said no break in necessary because it is a hand lapped bore.
Just go shoot it. So I did. Doug |

Clean, then shoot 200 rounds straight w/o cleaning (for chrome lined barrel).

I have a brand new chrome lined barrel bushy M4A3. Some guy told me that I should break it in by shooting a dozen rounds through it, then boresnaking after that. He said to repeat this about 100 times. Is this advice any good?
Now I'm confused: -Do I clean the bore first them shoot it a crapload of times? OR... -Do I just take it to the range, shoot it a crapload of times, then clean it WHAT SHOULD I DO? I'm very confused at this point. |
