Whisper pickles: What's new and exciting?

[Joelski]

If I recall I think DLC starts to get compromised around the 500-600 degree (F) range. That's just about two mags using 5.56 and you are over that threshold. Also another thing that I would question is the thermal expansion that happens. I am not sure how that type of coating would hold up to the expansion and contraction of the metal in a suppressor.

I would think that somebody would do some research into DLC, PVD, QPQ, etc. methods of placing durable coatings on high temp items like cans, even if a firing schedule is necessary to preserve a certain level of finish integrity. There are plenty of shops out there... maybe not with the depth of ROBAR, but still there are places like Vulcan doing this stuff, I would think they would have a vested interest in getting to market with a durable suppressor coating. Or maybe nobody cares, but I highly doubt that. Maybe the average civilian shooter just isn't hard enough on the can in the first place? You definitely don't see a lot of people shooting their firearms to the point that the can glows, which is what sold on the Alpha/Paladin in the first place.

Here is one that has DLC "inside and out"

And another...

Also there apparently is more than one 'variant' of DLC coatings.
