This has been a pretty discussed topic in the past. I think the general consensus is to have the nitride done by the company recommended by Defiance. Can’t remember who that is at the moment. I know you can get nitrided defiance actions from bugholes though. It just needs to be done right or it can change the heat treat of the parts.
The individuals I’ve talked to that have nitrided defiance actions said they would rather have DLC. It’s supposed to be a better process. That being said I have a nitrided defiance build coming on Thursday.

Use Club Custom Guns in North Carolina. His work is stellar and super nice guy. He’s one if he main ones several big shops contract out to DLC. I have had both and prefer DLC
My elite deviant is nitrated from core and also sent another deviant LA for DLCd trough chad..DLC hands down much better coating and abvious smother/slicker but its also cost 2-3x more vs nitrate.and DLC dnt go trough really high temp which people claim not too good for steel
Have you seen any of his FDE dlc'ed actions? I'm trying to find an example but no luck so far
Yes I actually have one. Dm me your number and I’ll text a picture to ya
Better process? That depends on what the end goal is. DLC and nitriding are completely different processes: one is a coating that builds up on the surface (DLC) the other is not a coating at all and rather a case hardening process that works via nitrogen diffusion into the steel's crystalline lattice structure.
ETA: what are the professional qualifications of these people who would prefer DLC over nitriding and what are their reasons?

Hi,
I am not sure why this "comparison" of which is better...DLC or Nitriding always comes up.
In laymens terms you are attempting to compare the benefits of paint vs heat treating...completely 2 different things for completely 2 different reasons for completely 2 different results.
If you want to increase hardness which relates to less wear and tear then nitride.
If you want to "slicken" up a surface then DLC.
Better yet just do both and be done with comparisons

Can you actually DLC an already nitrided metal?
Hi,
They have a "Duplex System" DLC which is a nitrided layer plus DLC coating so I am totally ASSUMING you can.

Yes. DLC is a surface coating, nitriding is a subsurface transformation
Does one cycle the bolt smoother than the other or more of sliding the bolt back and fourth smoother your talking about? Could you post a video of running the actions?
I sent Area419 my action for nitride.

I wouldn’t go as far to say that DLC is a paint. DLC does bond to the surface at molecular level and is only 4-7 microns thick. Most companies that use it do not even account for the process when it comes to tolerances it’s that thin. It increases the RC hardness of the steel as well to usually 80+. I know maybe not as hard as Nitride but it’s also applied at a lower temp. Once the DLC process is complete, short of media blasting it that “paint” isn’t going anywhere.
DLC does not increase the hardness of the steel. DLC is harder than steel (as it's a synthetic diamond), but the underlying steel is just the same hardness as it was before the coating.
I don't know of a nitriding process that can approach 80 on the Rockwell C scale, but unlike amateur metallurgists seem to think, harder isn't always better.
With regards to application temperature, maybe DLC is applied at a lower temperature. But I find very few people who can explain correctly why that would be or not be desirable.
Why’s da complete DLC job on a action usually cost? Ballpark
I wanna say $300-450 depending on if you want just the action or action and bolt.
EDIT: Whoops. Looks like i overestimated. I think mine might have cost more because I also had the lug raceways polished up for me. Looks like the price sheet shows it could be anywhere from $150 to 350 for receivers and bolts.

Several years ago I paid $275 for the barreled action to be coated if my memory serves me correct.
It bonds to and with the top layer of the steel and short of being blasted with media it’s not moving so in a way it does increase the hardness. Just depends how you look at it I guess. From what I understanding the coating/DLC that’s bonds with the metal is what has possesses the Rockwell harness.
You have many companies who offer DLC services to both industrial and after market companies. I don’t really think anyone needs to explain it other then, they offer a product and have conducted the testing. From R&D they have determined that when applied at a particular temperature it produces the best and most consistent results.
Hi,
Here is price list from Club Custom Guns using Ionbond DLC....

My comment about temperature refers to the comparison with the processing temperature for the verious types of nitriding.
I've been a mfg engineering for 25 years. None of what you're talking about here is new to me, and I understand it at a far deeper level than most gun forum people.
