Thank you for taking the time to share this!

This channel is criminally underrated! I have personally gained tons of knowledge and techniques from this channel and I am far from being a beginner. Thank you for sharing your thoughts and knowledge with us!!!

I had one of the Aero nickle BCG's and had an issue with the bolt. I contacted them and they sent me a 2day shipping label. Once they got it they confirmed the issue and replaced it. I had the replacement within a week and it now runs perfect. Sometimes customer service is everything when or if you need it. This issue showed me I made the right decision buying Aero and will continue because of that alone.

You kept shutting the demagnetizer off with the firing pin near it. That magnetizes it. Need to slide away and keep it away before you turn off.

I worked in a radio station and “erased” commercial cart magnetic tape every day. An engineer taught me that the bulk of the demagnetization occurs when the object leaves the magnetic field. Instead of just sliding, add oval loops while moving left to right (like a bi-plane at an air show) so that the field is broken in multiple patterns.

Great to see Aero continue to put out good stuff. Thanks for breaking these down and taking a look.

You absolutely do not need to apologize for experimenting (or accidentally bumping the camera). Every experiment is a chance to learn! Love you guys!

I’m glad to know many of us in the firearms community are starting to notice terrible QC issues from low to top tier companies. I’ve had terrible luck with LMT and HDSI in 2021 including this year. However, my boring Colt M4 Carbine’s made 2018 and before don’t have any QC issues. I was going to sell them, but now realizing it’s probably best to keep them!

I'd love to see a video where you compare and contrast different coatings used in the industry and how it may affect short and long term performance and parts wear. Phosphate vs nitride vs DLC etc. Love your videos

I'm on my second AR first time build though and I am thankful for these videos you make! The physicals and autopsys of BCGs have been extremely helpful and unbiased. I really appreciate what you do and the knowledge you share!

Fairly new Ar15 owner. Like to learn as much as I can taking things apart and learning about how they work. Just not about picking it up and firing. Your channel is by farrrr the best one I’ve found for learning. Thank you!!!

You should never apologize for dirty hands, especially if that's one of the most important tools you use to make a living, provide for your family, provide value to society!👍🤙

I bought one of these a couple months ago when they were marked down. Headspacing on the bolt was so off that it wouldn't chamber a round. Sent it back to Aero and they confirmed that it failed headspacing. Return process was straightforward, and I got my money back, so Aero's still OK in my book. I just happened to get a bad one.

I impulse bought one of these during the launch sale, so far I've been very impressed for the $120 I paid for it!

Love this channel! I've learned so much watching it, thanks!

Good to get a random test sample for verification. Some solid results, its good to see some efficient internals on these recent physicals. Thanks Chad and Donna.

Thanks for the update video man,helps any one who may not know enough tech info, enjoyed it,see you on the next one.

Outstanding review Sir ... Aero Precision is my goto company for all my builds 😉👊🇺🇸👍

Another great video, thanks for everything you do, and the education you provide. 👍

Very thorough. As usual. Thanks for taking the time to show us all how it's done.

i love your videos, thank you so much and never stop !!!

I’ve been waiting for this one 😈👏🏾

Thank you for the review. I’m running one in my 11.5 aero build and so far so good

I love Aero Precision, my go to receiver sets are the M4E1, I've built several AR's and have kept all of the Aero builds but sold all my cheaper builds. I have not used the Pro series bolts yet but will eventually. Love the channel

I really like the use of the bore scope as an option for the firing pin inspection.

The scope worked fairly well, actually. The tips look really clean, really well finished.

Love watching this channel.. helps companies to improve/fix any qc issues.. aswell as helping the end user to make informed decisions .

I've been WAITING for this vid

Love your videos because I always learn something. For some reason I was unsubscribed from your channel. The same has happened to me with other 2a channels,especially lately. Thanks for what you do!

Really appreciate the video. Several months ago I had to send an Aero BCG back to the company, because of a head spacing issue. They admitted there was a problem and sent me a new one. I’m a big Aero fan and will continue to buy their products.

Every video of yours I watch - I get jealous of all of those go/no-go gauges!

I am very happy with all my Aero Precision buys. Great fit and finish. And I just love the look of the M4E1 upper and lower set. Hey looks count in my book for new builds. Overall my Old Colt 60's and 70's factory Rifles and carbines still take the cake for classic beauty.

Attention to detail is outstanding. I am new to this. You have done your work in learning this and passing it on to others.

Highly interested by this particular bcg. So thanks for this video and the spread of knowledge as always.

I just bought one of these for a new build. I’m confident I made a good choice thanks to this video.

Good stuff, I have one Aero BCG only have around 800 rounds with it but so far so good, no malfunctions.

Another great video you two .

Absolutely love the Sharpie markers! I use them a lot in my profession. Also, Milwaukee makes a good paint marker.

I have to thank you for the educational value and professional presentation of your videos. I have a Springfield Saint .300 blk pistol that I have not even fired yet. I recently put a Q 7" tapered shoulder barrel on it for when my e-form 4 clears and I install a Trash Panda. Watching your videos has given me much needed insight. I have been examining various things as I gain knowledge and today 2/14/22 while examining things very close, I discovered the ejector roll pin was not seated correctly and was protruding out one side to the point where it has been making contact with the barrel extension lugs. I had to buy a few more things as being a retired professional mechanic doesn't mean I have the specific tools needed for gunsmithing, but I did buy what I needed to compress the ejector in and the correct punches, both of which I lacked. Edited 2/24/2022 To me this is just almost crazy. I had to wait to get a few more items, including my new 4oz hammer, the Brownells ejector tool, because that other thing I bought was crap, some specific punches and some new ejector roll pins. I also got my new Clymer go no/go gauges. In removing the ejector after removing the pin, the ejector was rather stuck and I had to grab it with some needle nose and really pull. After it came out and examining it with close-up magnified goggles, I discovered metal filings had been stuck in the ejectors slot for the roll pin then fell free once the ejector was pulled out. It was slightly magnetic and had some damaged edges from the filings which I cleaned up with a tiny file and made all nice but I was like, I'll be damned! I don't have a demagnetiser so it's just going to have to be for now but the go no gauges worked slick and the bolt carrier didn't lock forward on the no/go gauge but did with the go gauge.

I’ll be receiving my Pro series BCG today. As one would expect, I don’t have the gauge for the gas key so hopefully Aero has addressed this in the year since this video was filmed. Thank you once more for another great video, I love learning from them.

Thanks for sharing. I learn so much from y’all.

Thank you for making this very educational video! I learn a great deal about what aspects of the mechanism are important.

This was my first high dollar bolt and I was very excited about it. Been a great bolt in a thunder ranch build 👍

Great stuff as always- a real learning experience!

great job, your attention to detail is awesome

I don’t own any Aero parts but they seem to make pretty good stuff. It seems as if they are best value in the AR market today. Buy a stripped receiver set and everything minus the rail, trigger and barrel from them is what I’d do if I was going to snag their stuff. This BCG for 160 bones knocks it out of the park! Thanks for the review!

Man I love this education. Thank you !

Somehow just discovered your channel and it’s super informative

Wife works for them. They're opening up an additional 300k Sq Ft facility this month. Get your wallets ready, boys.

You’re fugin dope af bro thx for the knowledge drop always!

Magnetic parts trays huh. I'll have to remember that one. Good info as usual.

always good content, nice to see honesty on youtube

Great great review as usual! Thank both of you so much y’all just plain ROCK!

Very good video. I learn a lot about BCG’s. Just got into AR’s a few years ago and building my first. Make it short I purchased a Sons of Liberty BCG. It is a chrome one from Optics Planet and paid good money for it. I hope I made the right choice for my second build with a 18” Proof Research barrel

Aero having a better result than triarc 🤯

Love your videos! Thanks! The Demagnetizer will magnetize if you turn it off with the part (to be demagnetized is) over the machine.

That Dewalt screwdriver is my favorite tool. Just love it.

Amazing content as usual

once again I thought I knew something, thank you sir for again respectfully explaining to me the depths of my ignorance

Had no idea magnetic parts trays could magnetize parts thanks for the heads up!

I did experience a very difficult part to demagnetized in my life back in 1987. The Palm Beach County Divorce Courts eventually unmagnetized me for only $250k. Wish I had your Demagnetized machine back then.

Glad to see some Aero BCGs go through examination and pass. The last couple years it seems Aero has grown considerably and I regularly see them recommended as the "affordable but still quality" default option. Its just two examples but these do seem like solid options.

You deserve far more subscribers

Love this video. You were holding the firing pin over top of the demagger when turning it off each time. You did not do this the last try. That is why you kept getting magnetism in your pin. You were removing it but then putting a amount back in by doing it all with one hand.

2yrs later, I have picked one of these up. Just by running the charging handle a few times with the BCG installed, the coating is coming off in the typical contact points. Im not sure if this is uncommon or not but stood out to me since this is called the Pro version and people pay the extra $ for them.

I have some Aero stuff and it's pretty good to go. I did have a bad customer service experience with them about 5 years ago.

The worst bolt carrier I saw while I was active in the business came from brand C. I was struggling to make M4s run with a proprietary nickel boron coating and no lube. After borescoping a couple of carriers and realizing the gas seal surface was rougher than a corncob, we sent pics to the CEO, along with a pic taken inside a brand D carrier. No more bad carriers, and the project went much better.

Aeros builder kits are my go to. I bought one of their complete uppers once and swapped the barrel out to a fn and that thing is a beast. I took the original barrel that came with the upper and put it in my radical budget rifle and the barrel is sub moa. As far as I'm concerned aero is killing it.

Thank you Chad, love to see the Aero parts on your bench. I'm becoming a bit of an Aero fan boy so good to see an objective lens. Keep up the good work!

I have one of those BCGs in one of my ARs and it runs good.

Great video, I went ahead and got this BCG.

It seems like a lot of companies are promoting hard, and duty use stuff at a good price. Aero is just doing it best. You don't need to pay thousands for something you can trust.

Mr. Instructor, excellent very informative brother...what a blessing sir 👍☕️☕️✌️

Just a thought on demag'ing parts. The demagnetizer uses 60 cycles, standard Alternating Current frequency, to create a magnetic field that reverses 60 times a second. It you power down the device while still holding the part close by it you get that last, final magnetic field pulse and can actually magnetize the part you are trying to demag'. Move the part away from the machine and the demag' should hold.

I recently had a Aero Precision 308AR BCG with something wrong on the firing pin finish. It was mottled/splotchy in appearance and did not slide smoothly in the bolt right out of the box. Return was easy and replacement was fine. Headspace was tight enough that it would not close on GO gauge in a “match” chamber (read very tight). Barrel maker said it was less than 1 thousandth off and reamed the chamber very slightly for me. I am not complaining about the headspace - bolt and barrel makers were both trying to make it tight and tolerance stacking bit me.

Interesting. Remember hearing about them recently

I love my 13.7 pro upper and bcg, its the best fitment ive seen, and it seems lighter.

I'm currently in school for gunsmithing at the Sonoran Desert Institute with hopes of opening my own shop sometime down the road and I definitely will be concentrating/specializing on the AR platform. The info, techniques and measurements, and useful tools I've learned from your videos is undoubtedly invaluable for me. Thanks for the vast amount of gunsmithing knowledge you give! Really hoping I can make it out to your classes sometime

Im impressed, I'd buy that. Lots of quality for the money! Just wish it was chrome lined.

I did not know these "pro" series even existed. Great video

Excellent detailed inspection, makes me wonder if my “non-pro” version Aero Precision BCG would pass your test…

If they are tumbling the pins in a batch (likely) the simple act of the pins rubbing together can magnetize them.

When you send Chad a BCG and he autographs it for you. 😎

First And thank you for this great content

Even if I don't watch the vid, gotta click the like button for SOTAR!!!!

Love AERO PRECISION!!!

Thanks to Mrs. Chad for running the camera.

Aero does great work

The only PRO BCG from Aero Precision is nitride. I can find no reference to any DLC coatings for this product. It is advertised having a 9310 bolt ("shot peened and properly heat treated") and is HPT/MPI tested. Thanks, again, for your most excellent and informative videos! Cheers! P.S. I just bought one of Aero's HPT/MPI tested phosphate/chrome-lined BCG with a 158 Carpenter bolt marked "MPI": it is not marked as being HPT'ed either. This was primarily based upon your BCG coatings video, BTW. I've had zero issues with various Nitride, NiB and DLC bolts, but I thought it was time to try a phosphate/chrome-lined (basically "mil-spec") bolt...

Love your vids, curious what you use/recommend to help hold barrel in a vise block.

What a great video.

I feel like I have seen a desktop magnifying glass in some of your older videos, but perhaps one that has an option for illumination will help with displaying the firing pin tip a little bit better

I learn something every time I watch your videos. Thank you. where could you buy all the gauges you use?

Happy with Aero so far. Holds up after many rounds.

For the firing pin tip examination perhaps using something like Silly Putty would be good for a reverse imprint..?

I want to say thank you for your most excellent videos. I ordered a .308 BCG complete with duel ejectors in the bolt. My question is, can a bolt that has only 1 ejector be made to have a second ejector integrated into it like some military rifles have? p.s. you don't have to apologize in your videos, they are so thorough that I would never think less of any camera bumps or Arm's in the frame, just keep doing what your doing...

I just want to say that some parts being magnetic could be caused from if the manufacturing process uses an electric motor to cut the parts. Even engine machine shops the machinery can make the parts a little magnetic that’s why it’s best practice to demagnetize any parts that have been cut, ground , or machined if any way

You may be able to reduce or eliminate reflection when using the bore scope if you have access to a red light source.

It's all right to try new things when you're trying to find the tip

They have that Daniel defense staking. Aggressive
