melonite finished bhw barrel?

Came across this on the SSA website:

www.surplusammo.com/saa-exclusive-16-black-hole-weaponry-1-8-hbar-profile-ar-15-barrel-nitride-series-5-56-free-shipping/

So, did BHW offer salt bath nitride treatment before? Or did SAA do it themselves. Too bad it is carbine length gas port.
I know that the melonite finish is a long debate but it will make the BHW barrel even more awesome. 
Any downside of this treamment done to the BHW barrel? Do you vote against it?
I didn't feel like taking the risk myself by ordering the barrel from BHW then send it to the finishing shop for nitride treatment.

Thanks

That is not melonite and the terminology is incorrect. It is a blackening, black oxide, process that leave a durable black. It DOESNOT act like melonite. The true melonite proicess is done at high temperature. SAA does NOTHING to the barrels that they sell. They are merely a dealer for BHW products.

This is an explanation that Carl did for our future website

We start with an HS-84 (shot peening) preparation of the part. The overlapping dimples from shot peening create a uniform layer of compressive stress at metal surfaces. Shot peening provides considerable increases in part life. Compressive stresses are beneficial in increasing resistance to fatigue failures, corrosion fatigue, stress corrosion cracking, and hydrogen assisted cracking. We then finish the parts with a -DTL-13924 hot bath black oxide, which includes alternate specifications AMS 2485, ASTM S 769, and ISO 11408.

Our barrel steel comes to us heat treated. With our black oxide system, the barrel only gets heated to 286° whereas a nitride process heats the barrel to between 1050° and 1200°. This would ruin our heat treat. Other manufacturers use the nitride process as their heat treat process. We control for heat throughout the manufacturing process.

In summation applying a melonite finish to one of these barrels will ruin it.
