hey everyone,
I bought a ar15 CAR in February of this year..really didnt get it out to the range till today. I shot about 200 rounds through it. Obviously the barrel was very hot afterwards. It seems like it burned off the oil on the barrel and I could see a very thin layer of rust forming. I couldnt believe it. What can i do to prevent this? |

Yeah..I did that and was well oiled when I took it to the range this morn. I guess the oil burned off and it was very humid today so the barrel started to rust..Not sure You need to take it out the safe once and a while and just give it a light oiling. It probably sat around for quite a while. |

| It takes more than a couple of hours for rust to form. The rust was already there and the oil covered it up. One of my 3 Colt SP1 barrel was lightly pitted and the oil was a good cover up. After shooting I had to re-oil to cover up the rust . Finally I used steel wool because all the rust was under the hand guard. It removed the rust and the finish. Ths barrel was marked C MP B and was old and the finish was junk. I have since purchased a new surplus barrel marked C MP CHROME BORE with great parkerizing and mint bore and chamber. I keep it lubed and expect 20 years at 1,000rds. per year with know problems. |
| park will have rust poke through.Just rub it down with an oily rag like you were polishing it.This will remove most,if not all of the surface rust.Just keep it with a light coat of oil on it at any given time and ya won't have any problems.Ya might want to use some stuff called sheath,I use it on all my weapons.The ones that are stored look as new as the day they were put in the safes.I have a model 15-2 and Ruger Single six that I have had since 1967 and they look,with a little wear from holsters,just like they were back then,minus the wear of coarse.no rust.I use them a lot to. |
| Remove the handguards and inspect/treat the whole barrel. Don't use any steel wool or other abrasive on it. The absolute best thing you can put on it is Eezox, and rub with a cotton cloth. You could also use practically any petroleum-based lubricant, including engine oil and transmission fluid, but Eezox is the best for corrosion prevention and does a very good job on existing light rust. Like already said, the gun has started rusting due to improper storage and/or lubrication. They can rust in a safe or cabinet inside the house or even in a carry bag under the bed. |

Hauntedwinter, The humidty must be horrable out in North Carolina!!!! Check your bore and if it has no rust inside give it a good cleaning after your shoot and using solvent of a light oil your can/need to coat the bore and the outside of the barrel so it won't rust. If it's light enough outside then it can be scrubed off using a tooth brush. I hope your bore and chamber is hardchromed. Good luck, Impala  .

Rust remover followed by Duracoat, Ceracote, or some of the easier oven baked finishes? You can get Duracote in a spray can from Brownells as well as their Baking Laquer or Aluminahyde II. Or go all out and ion bond. Black-T would be great too.
I use one of the spray on, do it yourself type "finishes" on my barrels to prevent rust, especially under the handguards or rails. Especially under the rails since I don't remove them for cleaning. I picked up some Aluminahyde at a gunshow for a good price a while ago and had good luck with it. When I had the patience to let it cure long enough. The Duracote in the spray can would be even better I assume, and the part is ready to use in just hours instead of a week. I also had good luck with some high temp exhaust enamel. I don't remember the brand though. It claimed to have ceramic in it, a temp rating of 1100 degrees, and could be baked on for a faster more durable finish. |
