I'm now offering stainless steel bead blast with black oxide services for rifle barrels, pistol barrels and small parts. My black oxide supplier doesn't have a FFL so they can't take frames and receivers.
Barrels can be black oxide inside the bore without any consequence to accuracy, but I do plug the bores anyway or upon request.
The process is ideal for customers who want their stainless steel rifle barrels blackened but don't want to paint them, and for situations where you have a stainless steel part that will be exposed to high pressure but you don't want the heat treat to be affected by high temp processes like nitride/melonite, etc...
It is also a non-acidic process which avoids the possibility of hydrogen embrittlement (Hydrogen embrittlement = trapped atomic hydrogen from acid pickling or electrolytic plating turning hard steel glass-brittle, causing delayed cracking/snapping, especially deadly on 1911/2011 frames and firing pins after bad chrome or acid-based jobs.)
The black oxide finish is not ideal for handguns that will be holstered on a regular basis. The slide and frame will show holster wear easier than other finishes/treatments.
Why do black oxide?
1. Lowest-Temperature Process (Almost Zero Heat)
True black oxide on stainless (the hot 285–300°F alkaline process, often called “black passivate” or “gun black” for stainless) is by far the lowest-temperature chemical blackening method that actually works on stainless steel.
2. Zero Risk of Hydrogen Embrittlement
Black oxide (hot alkaline), an alkaline process – no acid, no electrolysis, no hydrogen generated
So while black oxide is cosmetically fragile, it is the safest and gentlest way to turn stainless steel truly black without any risk of changing dimensions, softening heat-treat, or causing hydrogen embrittlement.
I charge $75 for bead blast and black oxide of rifle barrels. I can do smaller items for $25 to $50. There will/may be a disassembly/reassembly fee and cleaning fee for barrels or parts that need to be removed from the receiver or parts that need to be stripped down and cleaned prior to the process.
I will process parts when I have a batch big enough to send in. To date, I've only done stainless barrels, recoil lugs and M14 gas cylinders but the company I use has done the process on parts for big firearms manufacturers.
Here are pictures from my latest batch.
Please e-mail me or call me to get an order in.
