Duralar: A New Coating for Firearms

The next new (of many to come, I am sure) coatings for firearms has been released by ProtoTactical, Duralar. Duralar is a diamond-based nanotechnology coating that “enhance(s) metal hardness and durability — and to provide other qualities as well.”

In the Press Release, ProtoTactical contends the carbon component of the coating provides a “natural, dry lubricity”. When applied to firearms, this means longer service life, smoother actions, and increased scratch resistance.

Details on pricing, what the coating can be applied to, and availability are currently not listed on the supplier websites. We will reach out to the companies and offer to test the coating.

Full Press Release Below:

TUCSON, Ariz., March 31, 2015 /PRNewswire/ — ProtoTactical, a Tucson-area manufacturer of firearms and firearm components has discovered a new way to significantly improve their firearm performance — by applying a special nanotechnology coating called Duralar™. Duralar is an advanced, diamond-based coating that is being used in a variety of industries to enhance metal hardness and durability — and to provide other qualities as well.

“Our use of Duralar coatings began as an experiment,” said Gary Palese, president of ProTactical. “I coated a few standard AR-15 trigger parts, mainly to check out the increased durability and wear resistance. But I got a nice surprise and an interesting bonus…”

“As soon as we installed a Duralar-coated trigger and dry-fired the weapon we immediately discovered that the trigger action was significantly smoother. Customers who tried it were amazed at the difference between the coated and uncoated triggers. They were certain that we must have changed the springs or reground the edges, or something! But the only difference was Duralar.”

“Because Duralar is a carbon-based material it has a natural, dry lubricity,” explained Andrew Tudhope, president of Duralar North America. “In firearm applications this means smoother action, less friction and no need for liquid lubricants, which can collect dirt and cause jamming. So, when you combine the intrinsic lubricity with Duralar’s hardness and increased wear and scratch resistance, it gives gun manufacturers a very useful suite of performance features.”

Sex Appeal

Gary Palese is also pleased with another Duralar feature, which he calls “sex appeal!”  “Duralar coating gives metals a unique pearlescent gray-black surface that is very tactical and ‘stealthy’ looking — which many of our customers find very sexy! So, because of its hardness and attractive appearance, I’m going to start using Duralar to coat our line of custom knife blades, as well.”

Introduced by Duralar Technologies in 2012, Duralar is an advanced, uniquely structured nanocomposite coating that blends metal and diamond-based components to achieve exceptional hardness, toughness, strength and a spectrum of performance qualities. It is comprised of multiple layers that can be configured in multiple ways to address different applications. Because of its many features Duralar is finding use in an ever-widening range of metal-coating applications. In addition to hardness, durability and lubricity the coatings also provide excellent corrosion and erosion resistance, and they are environmentally friendly, as well.

    Color me skeptical…

    • MR

      Well, it’s still April. They seem to have extended April fool’s day to cover the whole month. A throwback to the print age, I suppose. Other than that, yeah, that was pretty much an ad for what appears to be snake oil.

  • A

    What the h*** does “diamond-based” mean? And why are we supposed to care about that silly photoshop and/or lightning trick picture?! Filth!

    • Andrew

      It was also two different carriers. I’m actually in Marana right now, so I may take a look at this.

      • Andrew

        I handled this trigger and a used BCG today. Friendly and informative people. Subjectively, it seems like a quality product that is long wearing.

        • Grindstone50k

          Chance to get a full review up? I’m sure TFB would like to hear more.

    • raz-0

      I’m going to guess it is pretty much the same thing as ion bond diamond black and is nothing new.

    • Dan

      Because the pearlescent gray/black look is stealthy and tactical and most importantly SEXY!!!!! Agreed. Filth

  • Dracon1201

    SEX APPEAL? BWAHAHAHAHAHAHAHAHAHAHAHAHA! Tell me that wasn’t just in an ad for this.

    Edit: Went back and, yep, it is still there! BWAHAHAHAHAHAHAHAHA

    • noob

      “Diamonds are a girl’s best friend.” Marilyn Monroe knew a thing or two about wear resistance.

  • iksnilol

    Nice trick with the different backgrounds to show how different it is.

    Also all the “sexyness” business is silly.

  • Paul Epstein

    I don’t think there’s much point in being abusive towards a new product- it’s presentation might seem off, but fundamentally the fact that it’s a completely unknown quantity makes it simultaneously impossible to trust it or meaningfully criticize.

    The fact is manufacturers need to start getting independent reviews and testing alongside or before the big product launch. Almost no one is going to put significant money down on a product that doesn’t have any sort of corroboration, so the sales are going to remain miniscule while everyone waits for someone else to take the risk.

    • nadnerbus

      I’m always a little surprised at how firearms marketing is often so mismatched to the general firearm crowd. Gun people tend to be highly skeptical and conservative minded (in respect to new designs, not necessarily politically). You can go to any forum or comments section and find people with above average technical knowledge tearing apart press releases for new products all the time. And since we as consumers don’t buy mass quantities of product like TV infomercial wares, I don’t understand why they use the same marketing language.

      This might be a wonderful product, I have no idea. But as soon as I saw an exclamation mark in their release, my skeptical flag went all the way up the mast.

      Gun companies: data is king. Put your specs out there and leave the “new and improved!” verbiage on the cutting floor.

  • Phillip Cooper

    Almost all the buzzwords. Nanotechnology. Diamond. “Dura” in the name. “Dry lubricity”.

    They missed the precursor of an “i” in the name, though. It should have been called “iDuralar”. Then koolaid-drinking drones would be lined up around the block for weeks to buy some.

    “Sex appeal”? Seriously? WTF, are we selling adult novelties and crank pills here?

    Snore. BFD.

    • Robert

      What, do you not have sex with your guns?

      • Dan

        Is that weird?

      • Phillip Cooper

        No, because I don’t intend to kill or destroy my junk….

    • Shoulda called it Hammerhead Eagle i-Thrust coating.

  • Phillip Cooper

    “No need for liquid lubrication”.

    I’m calling total, unexpurgated BS on this one.

  • nova3930

    If one of your main selling points is “sex appeal” I’d say it will be a cold day in hell before you get my $$$. Phosphate works just fine and if phosphate doesn’t float your boat, NP3 has some proven benefits….

    • TechFarmer

      Exactly what I was thinking. I’m wondering how it compares in performance and cost to Robar NP3.

  • Andrew

    DLC coating found on motorcycle forks is meant to reduce stiction. If it works as advertised, that sort of coating would be very useful for the feel of single stage triggers. I’m going to try the product instead of bashing it.

  • Barry

    I need this new bcg and a case of RIP ammo. Then and only then will my gear be sexified. My only problem will be trying to fight off the hordes off women.

  • Bill

    I want mega tech, not nano tech

  • noob

    Hmm. I wonder if you coated a blade in this could you get superior edge hardness until the first time you sharpened it?

    It could be a way to make super hard scalpel blades or razors that are intended to never be sharpened but thrown away.

    Also if you coated AR500 steel (already a very hard steel) would you be able to break up projectiles that defeat AR500?

    • mrdakka

      Your idea about coating disposable blades is probably right on the money. As for coating AR500 steel, its going to have to be a pretty thick coating, instead of a micrometer coating to achieve what you want

  • Grindstone50k

    The first flaw with the product is whoever is in charge of marketing.

  • Core

    The Gun Cleaners of Maine and Texas sells a nano diamond gun lube, I have yet to try it but have a bottle ready for testing. I’m still testing two other lubricants.. I was told the nano diamonds fill pores in the metal and make a bearing surface.

    • The steels that quality firearms are made of don’t have pores.

      Silly marketing gimmick to sell people oil at over $5 an ounce.

      • UpChuck.Liberals

        Not quite right. All materials have pores, they may be very very very small but they are there. Thusly the ‘nano’ part.

  • Marcus D.

    If that is what this is, it would seem to be pretty close to the ultimate coating, and that the claims asserted are true.
