I plan to follow a non-chromed lined barrel manufacturer's break in advice, whether of dubious value or not. They recommend a succession of 20 shots with copper removal cleaning solvent used between shots.
Searching products showed some highly rated ones contain ammonia and caution against it's use near aluminum. What is best for an AR?
TIA

I use Hoppe's Copper Solvent for my ARs (and everything else). I dunno if it contains ammonia or not, but it works well enough.

Sweet's 7.62 was what I used when I had a precision rifle (Savage 110FP). It does contain ammonia. If you're worried about using such a product in proximity to aluminum (like AR receivers), get a rod guide for the upper. It will contain excess solvent. Also, you could clean the upper with the muzzle pointed down.

Thanks for the tips.
If the Hoppe's doesn't affect the aluminum I would think it doesn't have ammonia.

Breakfree bore cleaning foam is a mild copper solvent that's rated for use with gas systems. I've used it to clean ARs with no problems.

Takes off carbon great too.

The best bore cleaner I've found is Bore TEC eliminator.

I've had great luck with Gunslick Foaming Bore Cleaner myself. Not sure if it has Ammonia or not but it has never harmed anything I've put it on and I've used it on a lot of parts that aren't the bore, such as my bolt, which are aluminum unless I'm mistaken.

Thanks for the suggestions. I have several products to consider.

If I'm not mistaken the Breakfree Foaming Bore Cleaner is an ammonia based cleaner. And FYI I think the Breakfree foaming bore cleaner has been discontinued however the Gunslick brand is the exact same thing. I believe the Breakfree brand is just the repackaged Gunslick version. Read that on Arfcomm months ago.

I do believe that KG12 is now the top dog in copper removal with M-Pro 7 Copper Bore Cleaner not far behind.

I'm guessing they must be different cleaners if Breakfree's was Ammonia based.

Well that's good to know. I read this on another site review about the BreakFree version:

Model BF-BCF
Bore Cleaning Foam

Non-toxic and odorless, Bore Cleaning Foam chemically removes copper and brass compounds from the barrel in 15 minutes, and leaves a protective film behind to impede the accumulation of residue.

Bore Cleaning Foam has a pH value of 12 and can be used between the temperatures of -22° and 122°F. Packaged in an aerosol can, Bore Cleaning Foam is easier to use than other ammonia-based products. In addition, this cleaner also removes normal combustion waste from your gun's barrel, eliminating the need for a second cleaner.

The Blue highlighted made me think the BreakFree was ammonia based but just easier to use than other ammonia based formulas.

So either they are not the same thing or one or the other has ammonia or not!

I like to use Birchwood Casey's "Bore Scrubber" on my non-chromed barrel.

If you don't let it sit more than 5mins IT WONT hurt a chrome lined barrel period.

most copper remover has ammonia

AMMONIA based copper cleaners CAN HURT CHROME if left in a long time!! not a AR15 rec

BTW
MIDWAY has Bore FOAM that cleans copper with 0 ammonia


I bought more Break free again along witha Bore Foam by GS


UPDATE

used GUN SLICK FOAM COPPER remover

I will stick with CLP & non chlor Brake Cleaner

Bore Foam is waste on chrome lined M4

If Break Free Bore Cleaning Foam has been discontinued, I must have one of the last ones.
Got it Friday, August 20, '10.

I says "Non-Toxic" but, also "Avoid contact with plastic and wood parts of gun"

I just glanced at the Break Free Bore Cleaner MSDS, I see no ammonia in it.

I guess not as many KG12 users out there, but that link is very compelling for KG12...

Another vote for Bore Tech Eliminator. It works VERY well on copper and other barrel fouling, it is odor free, biodegradable, and non hazardous. In other words, you get something that works extremely well, and you don't have to be concerned with it harming your firearm, you, or something else.
