"It's not professional to leave marks..." God bless you sir. Your attention to detail is exactly what is expected in this business. My local gunsmith significantly dinged up my mk18 upper (DD parts over $1k) during assembly and said it was 'part of the install process'. I was shocked and will NEVER go back

I think that every shop needs a Shop Cat. When you start talking to yourself you can always say that you were talking to the cat.

You are an absolute godsend to the AR community. We appreciate your efforts.

*Out comes Berryman*. Every car guy: “Hello old friend” Careful with that stuff. Rumor has it that stuff is strong enough to remove everything but the shame of your bad life choices.

If you ever get brass transfer marks from a punch or hammer, copper removing bore cleaner will take it off - since brass is mostly copper. Awesome video!

Cute little Chonkers. The Cat, not you Chad.

That cat is adorable and I am not even a cat guy. I love doggies! Also, you are a GODSEND to our community. I learn so much from you.

the cat is crying for attention. It loves you. Thank you for taking good care of her.

These videos always end up filling my Amazon cart! Great info!

The cat portion was entirely hilarious hahaha; and great info

I just had my 1st carbon locked odinworx I had a beautiful 308 hand load that was grouping 1 hole 5 shot groups @ 100. 2 trips back I couldn't group. Last trip I took hand loads and 3 different types of factory ammo. No Love. I tore it down and it was so locked I could spin the whole AR10 with the tiny Allen adjuster screw. I soaked mine in DPMS CLAW OIl. It's perfect again. I'm headed to the range in the morning to test ammo. I didn't use my sonic cleaner as I was concerned about rust. Neat video. Thanks a bunch for posting it

You looked like you could do this in your sleep. Great tutorial. My "adjustable" product-info didn't even address this issue or procedure. So helpful.

You need an ultrasonic part claning tank!

Absolutely love your channel. Found it only within the last month or two. And I've been watching so many of your videos. Thank you so much.

I've been so Impressed with all you guys' thorough inspection process, I feel like I should ask for help with my Grendel build that wont cycle.

Dude I learn something new with every video. This guy is awesome

One pattern I've noticed with a lot of the firearms that come into your shop for diagnosis and repair is that they're all absolutely filthy. As if the owner has no idea that he has to clean it or simply refuses to do so. Now, I understand that the AR platform doesn't need to be spotlessly cleaned any time a round is fired like they make us do in the military, however I feel that if owners implemented a cleaning and maintenance schedule they will prevent many of these problems, or observe them before their weapon is inoperable. Lesson, Clean, lubricate, and take care of your firearms. They're an investment into your life and should be cared for as such.

A person taking pride in his work Gotta love it

That was a VERY informative video. I just installed the exact gas block on my 308 today.

so glad to see you use Chem-Dip cleaner! ill worry less about it damaging stuff on my AR & SCAR, I plug the barrel then use a pipet to pour it directly into the gas tube until its full, and let stand for 24hrs, that stuff is amazing, also used it to free a stubbornly stuck Suppressor!

You are a gun’s best friend and the viewing community, thank you!

this channel is criminally underrated

The leaf spring appeared to be slightly bound up the first time you installed it. Looks like it set a little deeper at the screw on the final install. Great video and I always appreciate the information you share.

I like to tape stuff up when using the hammer, or I will slip a piece of pvc, conduit or copper over a barrel even after taping. Great video, I just had to send my slr in because it was gassing from full open to almost closed in 1 click. I think they either sent me a new one or replaced a defective adjustment screw because now my wrench barely fits in the socket. After watching this, I just contacted them to see if I could purchase parts.

I have this exact same SLR Sentry (7) adjustable gas block on my AR. Although my rifle has never been even remotely as fouled as this example, once I recognized the block and then read the title, it caught my attention enough to watch the video in its entirety to see what had occurred. Needless to say the video was not just educational but entertaining as well. I have now subscribed to Instructor Chad's channel. Thank you for the video, Sir, I appreciate your thoroughness and your attention to detail, taking the time to touch up your otherwise minor scuff marks, despite the owner showing much less concern fo the overall condition of their own firearm.

Instead of oil, why not try a small amount of nickel based anti-seize on the adjuster threads?

Great video brother. Really well done.

Nice, Griffin Hammer Comp. Also, good video. Thanks for sharing knowledge.

Chad is absolutely brilliant!

Thanks for the knowledge very informative and helpful and the cat is awesome!

Thanks for the video..! Great stuff, I’m impressed with your shop. Bravo.... I am new to gas blocks. Building a pistol and a rifle and want to do some sub sonic single shot experimentation.. A couple of questions? How many rounds do you estimate you or the customer had before this happened? Did you soak it in Kroil, or just spray it on? Also what in your opinion is the best adjustable Gas Block in terms of reliability and serviceability Thanks in advance

awesome video

You would think he paid about the same or more than just replacing this gas block right? There about $100 ish

Damn fine work! Well done!

Fine job! Great video 😊

YOU SIR, ARE AWESOME!

I've never built an AR platform rifle and likely never will however your videos have given me an understanding of the platform better than anything I've learned from other videos, books etc. You are definitely a master at what you do and you also have a way of presenting material that makes it easy for anyone to follow. Thank you.

Thank you for this video I have the same block on my .308 never knew how it came apart or how to fully clean it! By the way on minei believe it's 5 suppressed and 7 non

screws that interact with the gasses, I tend to throw a little brass or copper Anti-Seize on it and it goes forever.

B12 chemtool was my go to secret sauce for any old vehicle, or small engine for years. You could spend 10 bucks on Seafoam or spend 4 bucks on Berrys magic sauce and do a better job. That and Marvel Mystery Oil, still run them to this day but I don't work on nearly as many old engines.

Hey Dr. Chad, what about applying some Molybdenum Disulfide grease to the threads before putting the adjustment screw and detent pin back in to keep them from locking up down the road? The Moly acts as a dry lubricant that embeds into the metal pores somewhat permanently, so the Carbon has less to stick to and breaks free easier even a long time down the road. I use a Molybdenum Disulfide grease GPL 215 from Krytox that's graphite free (which is abrasive to aluminum) as anti-seize on threads and even on the trigger sear because it's so dang "slippery" from 399°f even down to -32°f sub zero temps.

Why not pack the threads of the adjustable gas screw with high-temp nickel graphite anti-seize paste during reassembly?

I was hoping at the end you would show how to remove and throw away the adjustable gas block 😀

Loved the video. Where do you get replacement parts for SLR adjustable gas blocks?

I use Barryman's in a heated ultrasonic cleaner to clean valves and pistons of carbon. Instead of hours or days it can take just 20-40 minutes in most cases. I would imagine it would have a similar effect for a gas block like this, although it may need to be removed from the barrel in order to work unless you have a really big ultrasonic cleaner.

The "original" Chem-Dip stuff is chlorinated hydrocarbons, we had a bucket of it in the shop when I worked at Toyota that we used on exceptionally gunked up stuff; most stuff would just go in a heated solvent tank or parts washer (Very similar to the tank setup you show in one of your other videos only it had a plastic tank) and we'd use the Super Purple degreaser from the auto parts store... One of the techs knocked it over and that corner of the shop reeked for like 8 months

Chad, you're fuckin awesome. I have learned more than I could ever hope to watching your videos and following your guidance. Thank you!

GREAT JOB!

I want the cat cut please. My wife nearly lost it hearing "The cat has brain damage" lol

Those black glove really are a terrible back drop for that screw. I had a hard time focusing. Thank you for that Aluminum black. Its a great tip

I use just a little bit of anti-seize, on the threads only

Those Black Springs were replaced back in 2016. I've Talked to Todd about it. Pretty sure they would send out a rebuild kit. I'd replace all of yours. The Newer springs are much more heavier duty and more of a raw finish color.

All any of you AR owners have to do too keep your guns running, is clean your damn gun,SIMPLE SOLUTION

On a standard block, should we shoot some b12 or CLR down it on occasion? I was always under the thought it blew the stuff out. Maybe because this had a can it?

Would a dab of ep or high temp moly grease help keep the adjuster crew from seizing?

Is there a place to purchase additional springs? I had one break. They took care of me but I would like extras.

I’ll like it now and watch it later🤗 I believe!!

Phenomenal. Thanks.

If the adjuster is eroded and letting more gas by, why would you not just screw it in another couple clicks? That would do the same thing and save replacing the adjuster for a little erosion, unless I'm completely missing something. I run these exact gas blocks myself and on a couple different occasions, I've had to screw it in another click or 2.

If the tip of the screw is eroded , what does the bore that it goes in look like ? I never change just one sock , do you ?

Curious if this can be used on pistol barrels to remove carbon without it damaging the finish.

good to know, also, more on the shop cat pls

Don’t know if it’s still available but Prepsol also works great. Got that from Wilson’s book in the chapter about cleaning 1911s.

Always likes SLR products. How many rounds did it take to get this much build up?

Berryman's is some good stuff!👍

Would something like 33MS be a good thing to put on the adjuster screw?

What I learned as an armorer: Don't put an adjustable gas block on any of my personal DI Ar platform rifles. Thanks. However, I will be getting a tub of that Carb Cleaner.

I am woefully late to viewing this video (new subscriber)... Do you know if the “Berryman” will take anodizing off... Thinking of trying it on a .22cal., LR (serviceable) suppressor that is carbon locked

Would some automatic trans fluid work? I remember my neighbor pouring a quart down his carb and left it over night. The truck smoked like heck, but the carbon knock was gone.

Love the cat 👌🏼

I seen this product used to clean carbon build up on piston. Curious if it can be used to remove carbon build up on revolvers.

Do u recommend using anti seize on the adjustment screw?

I didn't think they made that stuff any more, stinks like ass but I now know of a new use for it. Thanks!

@13:17 are those blocks in your vise composite decking wrapped in leather?

Ever use "Free All"? Love that stuff...

QUESTION: in your experience, approximately how many rounds can be fired through an AR before the adjusting screw should be replaced because of erosion?

Can you recommend the brand of bits you use? And the holder on your wall? Also brand of Allan wrenches?

The smell of berryman carb clearner is burned into my memory for eternity. I swear I can smell it just looking at a picture.

Would you recommend putting a little Aeroshell on the adjustment screw?

You have a cool looking cat

What hex key did you use to remove the screw holding the leaf spring? Best

Orange gloves, more lighting please. Good video. Crazy cat.

Watching him work on that leaf spring and detent, it looks like thy should be reversible, yes?

Love Shop Cat!

Maybe I missed it, how many rounds did all this fouling? And, how often should it have been cleaned?

I am not a fan of the ultrasonic cleaner, however when using the Berryman Chem-Dip, using the tank heater function on a ultrasonic cleaner it is a force multiplier to the Berryman Chem-Dip. Doesn't work every time, it will most of the time.

OK, I need me some of that Berryman's love

Does it remove paint? I’m thinking to do this on an ak with adjustable gas block. But. The ak is painted a VERY unique color for my wife and I need it to not be harmed or discolored.

you should try some free all on stubborn parts !

Proof that you can indeed fix just about anything with a hammer

I have installed a gas block similar to the one you are working on here. I was wondering if you would recommend putting a small dab of grease on the gas adjustment threads to avoid binding... Renolit Replex grease is what I had in mind.

How often should an adjustable gas block be cleaned?

Those are some tough gloves...mine usually shred with a wire brush...

Thoughts on Adjustable gas blocks vs the BRT gas block inserts?

Berryman's in an ultrasonic cleaner works miracles. 😉

A magnetic pick-up, some brake parts cleaner, and compressed air would make the clean-up process faster and easier...

Any chance we can see the same with a Superlative gas block?

Shop cat made me sub.

How many rounds was fired before it carbon locked ? Was it ever cleaned b4 ?

Surprisingly a screw with a built in detent/thread chaser will lock. I wonder if you took a tap an sharpened it would help
