I took my new CQA out to the range last weekend and had a blast! Too much fun! I went through 50-60 rounds (Norc surplus) fairly quickly (new gun and I was excited) and noticed the barrel was really super hot, so I racked it and gave some attention to some of my pistols. Got me thinking ... do I need to take it easy at first - does this matter? Can I do any damage to the barrel if it gets too hot ... i.e. keep shooting even when it is already pretty damn hot?

Even tho it's a Norinco, AR's are war tools. Use them as such. No break-in period needed for war tools. Shoot 'till it catches fire, then toss it in the river.
 
Though I'm no expert, I do believe there is a break in period.
What I've been told is about every 5-10 rds you should clean the barrel with your bore snake.
Do this for the first 100 rds, or you may or may not effect your accuracy or longevity of your barrel.

This stuff does not apply to AR-15's or any chrome-lined barrel for that matter.
 
50-60 rounds is nothing for an AR15 with chrome lined barrel. Excessive heat can damage a barrel, but by excessive heat I mean like 500 in full auto with 30rds mags. Even after that your AR will be shootable....... Imagine a firefight in a war zone. I don't think soldiers think about excessive heat to their barrel, they just shoot and shoot and shoot ;)

I rembember a vidéo on youtube, they were shooting a Colt M4 until the FSP and barrel were red, the handguard was on fire and the gun was shooting and shooting. I think the gun stop working at around 2000rds in a few minutes as the FSP was melted and the gun was now a single shot.
 
A beta mag dumped full auto will have the gas tube glowing red hot....enough to light a cigarette off it....with no damage to the gun.
 
it's not physically possible to damage a chrome lined barrel of an AR in Canada by shooting it "too fast". you don't own enough magazines and can't physically load them fast enough.

I've never understood the whole barrel break in thing. Can someone explain to me scientifically how cleaning your bore every 5 rounds for the first 100 rounds improves barrel life?
 
Witness a member at my home range breaking in the barrel of his 10/22 at the 25 m line once, waited 3 minutes in between each shot, so his barrel can "cool" down, it was most curious sight to behold.

Where do people get these ideas? It's insane how much mis-information gets thrown around. I once had a guy ask me how often you need to clean a Glock. I just shook my head and walked away. I can't deal with that type of silliness.

I have run 400 rounds through in 4 minutes (including ~30 seconds to clear one malfunction) and the rifle still shoots fine. Yes, everything was scorching hot. There is nothing wrong with giving your rifle a rest and letting it cool down, but it is extremely hard to overheat an AR with our mag limits and semi-auto fire.

First off, bore snakes aren't a great idea if you like the bore of your rifle. Second, not even the super OCD target shooters can agree on a break in procedure or the results they get from it. If those guys can't find a measurable advantage there isn't one.

Nor any other rifles, it is all hooey.

The idea is that this procedure helps smooth out the small burrs and imperfections in the bore, leading to better performance than otherwise. About the only credible results I have seen was from one of the long range target guys and he found that break in results in a barrel that fouls slightly less and cleans more easily. I am not sure even those results are repeatable by others. BFD, I say.

Now that's awesome. I broke my new 10/22 barrel in with a 6x25 round mag dump...

I dont believe in barrel break-in either, the barrels already heat treated. Theres nothing left to do to make that barrel last longer when shooting. An engine needs to break in yes not a barrel
 
Just how is a bore snake bad for a barrel vs other cleaning methods? There ain't nothing on a bore snake that's harder then the bullets you fire through the barrel... I think that's more fud.
