Does DLC Make a Difference? || Walker Dark Matter BCG

[@corruptbanjo27]

DLC "Diamond Like Coating" is also used on Geissele's Enhanced BCG's, and A Staccato 2011 is also fully DLC. Pricey.

[@randyreviewsit]

Geissele uses nano coating it’s a bit different but lead and steel arc’s come with dlc

[@Roadking556]

Correction... " Diamond Like Carbon" is the coating.

[@joenunya8449]

@Roadking556 same thing different marketing

[@sluttybutt]

DLC is also available on BCGs who OEM for others, like toolcraft. It's not revolutionary or exclusive to price-gouged makers marking up toolcrafts with a different logo etched on them.

[@Will-W]

Zero issues with my ugri upper and BCG. Cleans easy and smothered in synthetic mobile 1 grease.

[@mitchculpepper738]

Easiest way to clean your BCG is with Aero Kroil and compressed air. I may completely disassemble the BCG once a year but have never had a problem with the gas key, gas rings, firing pin, ejector, extractor, or bolt. Just blast it off, wipe it down throughly, and lubricate. For lube I use synthetic motor oil mixed with Lucas red and tacky grease. I use this on all my guns. I leave it thick enough to stay in place but thin enough to smear flat on smooth surfaces. This holds up well especially on the charging handle and carrier. DLC, chrome, nickel boron, etc. are all easier to wipe off but I’m not convinced of their lubricity when dirty and or dry. Definitely not worth an extra $100 to me but to each their own.

[@Specter_ZO6]

I’ve always used cryptic coatings BCG. Fantastic product and just stupid easy to clean too. I’ve run suppressed and unsuppressed on 16” and 18” barrel. No issues with it at all

[@TerminalM193]

I've found that with DLC and other similar "slick" like coatings that you have to use grease on all friction points. If you use thinner oil it's almost like it immediately is pushed away from all friction points and refuses to hang on to the bcg coating.

[@mobilegamersunite]

Makes sense. Lucas grease ftw!

[@steveninaz9576]

You should use grease of friction parts. "Lube" oils are now meant for friction parts.

[@mobilegamersunite]

@steveninaz9576 depends on tolerance as well...I use grease on the AK because it works with lose tolerances...ARs stack tolerances more easily 🤔

[@chrisrosenthal1210]

I'm of the same opinion. Seems like they just sling it off pretty fast. Phosphate will hold lube where it's needed or close enough it keeps moving back to the friction points with motion. No doubt it will clean up easier. One of the easiest BCG's to clean I've ever had was an old Low Mass VooDoo Lifecoat with the integrated gas key. It's blasted, nickel coated then has some PVD barrier on it over the nickel. Quick with a paper towel and it was good. I put no telling how many rounds on it and it still looks new. I'm running a chrome JP LMOS (3-gun rifle) right now but still have that VooDoo. Small Arms Solutions channel has a really good video on all the different coatings.

Oh it's good shit. Works great on endmills in the machining world. Also great to keep your nozzles alive if you 3d print any metal or fiber filled materials. Tool life. As far as milling, typically the dlc coated endmills are recommended for things that do not have iron in them. The bolt carrier is tool steel. The reciever is aluminum so..... I guess a high round count and dirt/abuse will tell you if it's worth it or not.

[@LackLusterMedia]

I've been running cryptic coating bcgs for a year, and they are ridiculously easy to clean.

The first bolt he had to hammer out of that poor gun was so sad. That is what happens when you do not clean your firearm. At some point it does not matter what coating a bolt has. The condition of you chamber and the bolt matter, keep them clean. It is really not that complicated. I have BCM and Colt bolts with thousands of rounds. I also have DLC Geissele bolt. They are all ''easy'' to clean because I clean them every time I shoot them.

I got the muzzle device made of inconell by Walker defense. That was the ticket! Looking thru the scope after busting off a round, no muzzle rise! I was eyeballing that bcg later when it came out. Might have to get one…

[@WDLC1911]

The only drawback with PVD (physical vapor deposition) coating is that they do not hold lubrication. Hard chrome bolt carriers are similar in that regard. Yes, they are slick but if they’d not polish the surface finish to the point where it’s a mirror finish they’d be better. These coatings are what is termed conformal coatings. The finished result will conform to the surface roughness of the material being coated. I’d like to take a bolt carrier assembly and notrocarburize it and then PVD coat it.

[@SamClemens-d5n]

That's a lousy test, but the difference between them is so great that it still showed how much more easily the DLC was cleaned.

I worked for a custom gun maker, and as a bonus one year, I got to build my own rifle on the company's dime. I titanium nitrided the action and the entire bolt before applying the DLC coating to both. I apply G-96 synthetic grease when I use the rifle. I have shot it in -30 with no issues; though I am not dumping 30-round magazines or cooking the barrel.

[@menegene4129]

There's at least a couple of armorers in every state with a horror story about a Soldier who managed to strip that coating. Because even though it would pass a WHITE GLOVE inspection, said Soldier's leadership insisted it was still dirty because they confused DLC with carbon residue (this is why desk pogs should NEVER be in charge of firearms turn-in). So when this poor soul finally turns the weapon in, the armorer tells them "Soldier.....you were supposed to clean the weapon not DEADLINE it!!!"

I agree 100% it is all in the post surface finish before DLC is applied. I have been using Cryptic BCG's for a long time due to this reason. They polish a ToolCraft BCG then apply a PVD finish. I shoot suppressed and all I need to do is wipe them off with a towel. The ONLY place on the BCG I have to scrub is on the back side of the bolt behind the gas rings.

[@richardturk7162]

Never had any issue cleaning any bolt carrier. I have a nickel boron bolt and you can just wipe the gunk off no need to scrub it. Nickle boron and chrome can change tolerances so that can be a concern. Me personally have never had either one have tolerance issues and they work just fine.

The US Army tested ArmorLube, which is a version of DLC. Out of the 6 tests they performed, it matched phosphates in 2 tests, outperformed it by a modest margin in 2 tests, and saw FAR better performance in the other 2 tests. There were no tests where the phosphate outperformed the DLC. The US Army liked it so much that they added it to their spec sheet. It may not gauge as well as phosphate/chrome, but it absolutely has far greater benefits.
