I'm not kidding.
I have two rifles built by ORF, and finished in their "blark" finish. One is a polish underfolder, the other is my SEAK rifle.
The SEAK has been shot once, the underfolder never.
Both are starting to develop signs of rust on the inside and outside of the receivers. They are both kept in a safe, indoors.
I noticed this when I got the underfolder out to show someone, and noticed orange discoloration around the folder hardware. I opened the receiver cover to find every seam and joint on the inside orange, with a rust-like deposit all over the inside.
I cleaned the internals quite well, and sprayed the whole thing liberally with CLP.
Again, this is an UNFIRED gun!
I own at least 50 rifles, about 12 of which I built myself and finished with Alumahyde. Not a single other gun has anything like this.
Any idea what is causing this? Anyone else have a similar experience with this finish?
I am temped to break them down completely and finish with Alumahyde to prevent any more air from contacting the metal.
