Any recommendations for company that does DLC and/or Melonite treatments for rifles?

Which is most corrosive resistant?

Plan is to treat a chrome moly Remington 700 BDL that I have - versus buying/building a new rifle in stainless, etc. Cerakote, etc is not option. I can do those myself.

Thanks!

H&M metal processing in Akron, OH for black nitride. Melonite, if you are not aware, is a tradename for black nitride. Common tradenames are QPQ,Tenifer, Tuftride, and Arco.

Corrosion performance that I've seen in testing is better on DLC, but we're talking extreme tests. Black nitride is still excellent in normal conditions that a firearm would see. For an example, when was the last time you saw a SIG or Glock slide that rusted badly? Those are black nitride treated, and are very durable.

IMO, DLC is great when you need the slickness and wear resistance, and excels in specific applications. I think black nitride is a better general firearm finish.

Thank you!

I have had more than a few rifle barrels black nitride treated, and by several different companies. Black nitride is an ad-on for wear resistance, although the finish is very corrosion resistant. The engineers at these heat treating companies that offer black nitride have said, "new, very low round count is best. they need to be completely cleaned of any carbon and copper fouling before treatment". I would ask if the barrel needs to be separated from the action before treatment. After treatment, the bore needs to be scrubbed clean, and that is easier to do before assembly. Very hot soapy water has worked well for me. Any wear of 'cracking' in the bore may be detrimental for a successful result from treatment. Any fouling left in the bore may be detrimental, also. Id talk to the engineer at the desired treater before making up my mind about black nitride treatment. JM2C

I've had a couple of rifles done by H&M. They are a good company to work with and used to give a price break if they treat more than one firearm at a time. I will say from experience that if your rifle is new you should break your barrel in first before sending to them for treatment. The hardness of the metal, post treatment is difficult to work on, found that out the hard way from the gunsmith that was doing some work for me. I also asked H&M for a matt finish, which I'm very please with.

All I've seen was hard and lasts forever but easy to scratch so don't use the gun!

OLd world rust blue is still the best.
