The more I watch these videos. The more it becomes apparent that quality and brand name isn't the issue. It's about maintaining your firearm properly and making sure you inspect every millimeter of it. Knowing what can go wrong and what to do to fix "defects" is ultimately your personal responsibility. I sir, appreciate everything you teach us. The information is priceless. Thank you.

I’m so addicted to watching these BCG breakdowns.

Brownells puts out consistently solid products.

Im not a fan of long videos but your videos are so informative and there is no bullshit talk all the way through ill watch these all the way through no problem.

Love your vids. As someone that's been an aerospace and medical machinist for years, I can appreciate your knowledge, thoroughness, and skillset.

“That one might be gone forever” He said after the Colt Extractor Spring went flying 😂

I have found useful information on building an inspection with other videos, but never at this concentration. Thank you very much.

Outstanding as always. Thank you.

I just ordered a .308 from them. Thanks for this!

To err is human. I just try not to be too human. Your honesty and integrity is admirable.

great video again! now I am even happier with my Hawkeye bore scope.

In a different video you mentioned something about not being a fan of scraping when cleaning. I was in the Army, and just a dumb grunt, so I'd used the machine gun scraper tools on my issued M16 and M4 plenty of times. It would be nice to see a video on how to properly clean using the basic cleaning kit.

Awesome videos man it’s amazing what I’ve learned watching these! Thank you!

Thank I just bought a Brownells BCG and was wondering about the staking and bolt.

Great video. I’ve never heard that the extractor should feel like puppy teeth. I’ll have to check that out. After doing some research for replacement parts I ended up getting a whole new bcg. Not sure why I ended up getting one made out of Formula one 🏎 transmission steel but I did..( jp )

Master class, every video. Keep it up!

Purely addicted to these Physical / Autopsy videos, also shocking to see the results on some!

Borescope is the only way to go to install as gasblock. Highly encourage anyone to buy one. I bought the teslong, and while the adjustment sucks; it's the way to go.

Hey Chad can you do one on adjustable gas blocks and how to adjust them. Enjoy the videos!

As a machinist, I cringed a little bit when he zeroed the micrometer.

Hawk eye is great. I use them for locksmithing.

Perfect way to start the day.

Yes! Another video!

@School of the American Rifle Do you have a lower that you would recommend? Which one, in your experience, seems to produce lowers closest to milspec, so that components are less likely to have compatibility issues? Or is that a unicorn that doesn't exist?

About Commercial Gas Blocks: Chad, have you encountered any gas blocks that do not take into account the .035" handguard cap thickness?

The Hawkeye looks more like a medical endoscope.

Brother you make the most informative videos I got the 3 bore setup off a website that had posted it but really needing your red silver and green gauge sizes you you for checking the bcg can you provide where you have posted this or the sizes please sir trying to get some tools and gauges before taking your class.. and your boat rail go no gauge would be amazing to know what you use or where to buy them

How did you find these gauges? I’d love to purchase some for my own! Especially the bcg gauges

Watching all the inspections on high-end to the lower end BCG's, only 100% way of knowing that you have an in spec BCG is by if not all of the tools but enough of them in determining close to 100% BCG or cough up the cash and send it to you to do an overhaul.

Follow up question rearming your Hawkeye borescope. Per Gradient Lens, they offer two video systems- their “high end” Sony ($3,000+) and their less expensive system, which I don’t recall what it was called. Which of the two video systems do you use or recommend? Also, have you done a video on gas block alignment?

I bought a BCM extractor spring upgrade kit (several actually). Do I need to use the donut,as well, and if not, why??? Thanks for taking the time to answer.

Would love to see an autopsy on a 308 bcg from time to time

Did you ever find the Colt spring?

@13:24 I had a CMC enhanced bcg that was causing my buffer to make contact with the buffer retaining pin. The BCG was too short.

13:16 “Nice” 😎

I must have had some evil puppies. All mine had sharp pin like teeth.

Why is the ejector test always done off camera?

“That one might be gone forever.” That has happened wayyyyy to many times with me!

So is there a simple way you have found to determine if a barrel and chamber is chrome lined or not?

👍

I've bought one chromo bolt from Brownell, and I have to say I am not empress. There where bures, scratch on the bolt. If I was going to put it in my upper it will cut into my up. It was just bad. I am buying from BCM, badger ordance or LMT.

Do you have a link for the Amazon bore scope?

Spring cling to sole of the shoe

You might have received this question before, but why do you only use the field gauge and not a no-go?

Any chance you’d consider doing one of brownells lightweight BCGs?

Have you ever taken a look at the BRN-180s? What do you think of them in comparison to traditional DI ARs?

Have you ever inspected a lightweight brownells BCG? I have two. Both are different design wise and one does not run in my gun. Also has cracks on the carrier key. Thanks!

the back hole eats another spring...

Does anyone know who the actual OEM of these bolt carriers is?

These are all I run and I've had no problems.... have a 308 also

Just got to work, guess I’ll be late this morning.

I believe Microbest makes Brownells bcgs.

Is your Sionics BCG break down available on your KZfaq? Haven’t been able to find it.

Are the misaligned carrier keys from a particular manufacturer or company or are they from several different ones?

My BCG and firing pin are all magnetized because my dumb @$$ used a magnetic tray when cleaning them. Did I ruin it? Can it be fixed? (shame)
