Break-Free Bore Foam does a great job cleaning out powder and copper residue. However, I learned the other day its like 50% water! This concerns me because I am sure some of it migrates into the gas port where I cannot clean it out. Hopefully it hasn't caused any rust there.
In the future, I guess I can blow out the gas port with compressed air. Live and learn.... |

Find the MSDS for the product; it lists the active ingredients and their relative percentages.
Copper solvents contain ammonia, so they use water as a carrier. If you read the instructions, you will notice that you're not supposed to leave the FBC in the bore for more than 10-20 minutes. Just give it a normal cleaning/lube after the FBC and you'll be fine. |

We have gone through this MANY times before. BF FBC is perfectly safe to use on your AR. When BF FBC first hit the shelves, I had concerns myself. Having personally been in contact through email with an engineer from BF, and having used the FBC for years, I can report to you with total confidence, that BF FBC will not harm your weapon. |

I have no concerns about it harming the weapon, only about some of it (with water) getting into the gas block area where I can't get to it.
Does anyone make a really long pipe cleaner for swabing out the gas tube?? BTW, I called Break-Free too and according to the MSDS, it does not contain ammonia. |
