Is there any benefit of slick coating (DLC / WS2 / moly) internals of a competition gas-gun?

[Noobilicious]

I am sure I am not the first person to have this thought: Is there any benefit of slick coating (DLC / WS2 / moly) internals of a gas-gun for competition use? Would it improve shot-to-shot consistency or smooth out the recoil in any way?

If someone wiser has thought this through or tried this, please share your take with me.

Not exactly sure what you mean by "internals", but bolts and bolt carriers have been treated with a wide variety of processes/coatings.

Ionbonded Young Manufacturing bolt carrier . . .

NP3 coated TRIARC bolt carrier . . .

JP Enterprises QPQ nitrided bolt carrier . . .

.....

Thank you @Molon, by internals I was referring to bolt and carrier group.

Did you notice any benefit of using these coated bolt carriers compared to regular nitrided ones?

Had a few NP3 BCG's. They're smooth. They clean up easy. That's it. Had some BCG's with "proprietary" and undisclosed coatings. Same thing. Had extremely smooth nitrided ones like the JP that do all the same things as nickel boron, had cheap rougher nitrided BCG's that don't. The end.

Always wondered what it would be like to have an NiB coated receiver like WMD makes paired with an NiB bolt for extra smooth magic. But I don't believe it would be of any real benefit.

I haven’t noticed a performance difference over phosphate coating, but the melonite, dlc, etc clean up faster than phosphate.

I had a NiB Seekins IRMT-3 upper I paired with a NP3 carrier. No real difference but it looked pretty at least.

I have a young manufacturing chrome BCG in a rifle I run suppressed 100% of the time. The can has very high back pressure and the phosphate and nitride bcgs I had in there before would get gummed up after a few mags. The chrome bcg just keeps running. Plus its a lot easier to clean.

The days of bad BCGs and broken bolts are long gone, if you stick to established names. Clearly, DLC (aka Ionbonding) is better and Nitriding is good, but the old fashioned military spec chrome lined phosphate BCGs will oil are going to give you the same performance on the first 8,000 rounds. Some of the BCG enhancements remind me of the guys with Honda Civics and the load mufflers that make the car sound like a motorcycle.

like steve miller said "everything is better when wet " unless you just like the feel of rug burn .

I always though they sounded like a gas weed eater...

There is a term for those mufflers: Fart Cannons.
