Rust preventative on CM barrel

[Closetohome]

I am in the process of having a 510 Whisper built and trying to find a Stainless fast twist cut rifled 510 barrel was a huge issue...thanks to someone on this forum I was able to get my hands on Brux 9 twist CM barrel that they had squirreled away.

My concern is that living in a humid climate on the gulf coast and running a suppressor rust in the bore/chamber will be an issue. I am torn between having the barrel Cerakoted and just being meticulous about keeping the bore and chamber lubricated or sending it somewhere for salt bath nitride or melonite of some sort, or other treatment. Has anyone had experience with this process, or have any recommendations of places that do this?

you could send it out to be qpq'd. had a client do that on the swampy end of Texas a few years back.

and shooting a wet chamber is asking for trouble, if you're one of those shake the oil off it guys you need the inside of the barrel clear before you shoot.
