I've learned more about the AR platform from SotAR than in my 24-year military life dealing with Small Arms. The explanation of the gas function as it pushes the bolt forward has completely changed my visualization of the firing sequence. Thank you and glad to see Rebel again.
This is just amazing! I sometimes take for granted just how much engineering has gone into the BCG design. So cool to see how it functions via the cutaway. Thanks for posting!
Despite having learned a good bit about the mechanics and intricacies of the AR (a good bit from your videos) I was still able to learn a new thing about the pressurization in the BCG taking load off of the bolt lugs, thus prolonging their service life. The content you put out is simply astonishing and the internet and UA-cam don't deserve you.
God this video is SO cool! I LOVE all this nerdy stuff about the AR, I absolutely love the process of when, where, and why you test! Please don't ever stop this train Mr. A! All the testing and info you provide for the community, might I add for (FREE) here on UA-cam is invaluable! Thanks for all you sir! Merry Christmas to you and the family, and may 2022 bring the Biggest and BEST year for SOTAR yet 🤘
Thank you for teaching us peasants the intricacies of the American rifle. Keep sharing your knowledge, I learned something new today. I wasn't aware the AR keeping forward pressure on the bolt until the rearward movement starts. Interesting. 🇺🇸💯 I've been a machinist and a welder -fabricator. So I can appreciate the use of pin gauges etc. I never served in the military and only handled a couple AR's on the range. But I'm more confident about the rifle now after watching a few of your videos. If I had to "pick one up and run it" I'm better off now with the knowledge you're teaching. 👍
Great instruction. In the army we were told the gas pushed the the bolt carrier back. Did not even know that gas was getting inside the carrier and pushed on the bolt. I finally understand why there are rings on the bolt. Stoner did a great job designing this system!
OK on top of everything else, you’ve got the best wife a man could want! I more or less understood what was happening inside the BCG, but seeing the cutaway is a fantastic teaching tool. Seeing the actual parts works best for my brain. Thanks! ETA: there is so much good information here that I miss things the first time through. In this case, it was your comments about the firing pin retaining pin possibly indicating a poor gas seal for the bolt tail or excessive BCG speed.
This is absolutely the best video I’ve ever seen on the Mechanics and Theory of AR operation.. those little bits of gold like a beat up bolt retainer pin = tail shaft leakage.. amazing. This video should mandatory in Basic Training for all military branches. I know they aren’t Armorers but they know the how and why. Thank You brother for such amazing content!
Respectfully, the load the bolt cares about from a fatigue life standpoint is the load at peak pressure. By the time the bullet passes the bleed orfice in the barrel, the chamber pressure has dropped to 1/3 or 1/4 of peak, meaning the pressure forward on the bolt is a fraction of it’s peak value. Bleeding gas into the bolt carrier reduces the contact load between the bolt lugs & the lock extension lugs, making it easier to unlock the bolt.
this guy is awesome.. I did 20+ yrs in the infantry, and I think this small but clear period of instruction would have been very beneficial as a constant carrier of this weapon system. It would make a better shooter and caretaker of the weapon. ensuring the shooter understand the type and quality of required maintenance needed to keep the firearm in good firing condition. great class!! wow!
I thought I understood everything about the operating cycle till I watched this video. Sharing such great educational information with the public makes you a true patriot.
So glad you mentioned the gas rings lining up. I remember learning that in boot camp and always thought that was a necessary check. Also didn't know the gas rings compressed as they're put in the BCG
Amazing content. The firearm cutaway is what happens when skill, understanding & passion meet: a work of art. Seriously. Thanks for your dedication to sharing your knowledge. May you continue for as long as you wish. Liked how Rebel answered when spoken to. 😎
This is an INCREDIBLE video. Your wife hit a home run with that Valentine's Day gift. No amount of cartoons or animation will show as clearly how the bolt and bolt carrier interact during firing as you did with the actual metal parts. Now I know exactly why the bolt tail is always caked with carbon, and I also know that I probably need to do a better job cleaning the inside "chamber" of my BCG that is hidden so it's "out of sight, out of mind". Thank you for this.
No apologies for the interruption needed. After all, his name is Rebel. Been a sub for... idk, a couple years. I love learning & gaining better understanding. You can't get this level of information anywhere but here. Thank you for doing what you do and doing it so well! You know you have serious students when there are zero dislikes!
I had a good idea of the BCG's operation inside the weapon and that cutaway along with your explanation confirmed it! thanks Chad... good to see Rebel again too 👍
This is even more clear than those cut away graphics videos showing all the intricacies. It's kind of like photography and football. You can learn a lot by just watching videos like that but you really have to have someone who understands the thing well to explain it properly.
When I was learning, I had so much trouble figuring out why the rifle wouldn't cycle. I LOVE videos like this, they help me understand the mechanics of what's happening so I could better diagnose the issues. Thank you!
I’ve always appreciated the talent and skill of the mechanically inclined. But what makes SOTAR truly remarkable, is your ability to simplify and share these lessons with others. Thanks.
I am SO glad I found SOTAR. Thank you for providing this well presented information. I have learned more about the AR DI platform in the last week from watching your videos than in last 32 years of owning one. 👍🏼🇺🇸
Really interesting to watch this deep dive into the AR system. It further exemplifies how polar opposite the design ethos was between the M16 weapon system and the AK47.
I'm one of those guys that learns by seeing it all first hand. Seeing you take the time to do some educating like this brings me joy my dude. Thank you.
I really need to remember what you said. I wished I was watching this while I have my ar open up for cleaning/oiling. I liked your parts. Your video just popped up. I am going to subscribe. I love your cat.
Of all my time working on AR's I never made the connection that the same pressure that pushes back on the carrier also pushes forward, relieving some stress on the lugs... Best educational channel on UA-cam. Hands down.
So after watching this detailed demonstration, I learned something that I never thought about. Which is, the gas pushing/making forward pressure on the gas rings and bolt. You say that it removes some of the load from the lugs but wouldn’t this also help with the unlocking? The gas is pushing the carrier rewards but since the gas chamber is also pushing on the back of the gas rings creating forward pressure on the bolt, this should also help the cam rotation! Very useful video. Goes to show you how useful the D.I. System is. Whenever someone makes a comment about its faults, if they only knew how everything is working together they’re actually beneficial to the operation.
Marvelous explanation of the gas functionality of the venerable AR joystick! I built one from scratch a while back. The cutaway vastly helped me to see/understand how she really works. A thousand thanks for putting this together .
Absolutely the best video I’ve seen on the gas system. When piston conversions for ARs first became a thing, and were all the rage on fanboy websites, I tried to explain the disadvantages I saw, including increased bolt lug wear, but was shouted down by the mobs. BTW, you’re a great teacher as well as being extremely knowledgeable.
I've been looking for a video that uses AR-15 cutaways for ages...finally found yours. What a great job of explanation, too. The visual of the cutaways with your explanation makes all the difference. I didn't realize that there was a purpose for the forward pressure applied to the bolt at the start of the cycle (unloading the lugs). The rest I knew but couldn't really visualize until seeing the cutaways. Your explanation of what you've found in these guns and what could go wrong is very educational as well. Also, your troubleshooting gauges are well thought out and easily understood. The cutaway of the gun itself is great, but the cutaway of the bolt carrier showing how the bolt and gas key fit into it and how bolt and bolt carrier move together is priceless.
This was an awesome video! I understand so much more than I did before about the operation of the rifle. Now I know why some areas are so dirty when it's cleaning time. Loved seeing Rebel too.
The guy who got me into shooting at the range always insisted AR-15s are horrible because they throw gas into your action and i couldnt believe it was that stupid because so many people (and militaries) use it. This video properly showcased the reason, the up and downsides and the inner workings of the AR action. truly, a very nice video and a great piece of teaching equipment.
I'm watching this long after the fact but thank you for the visual and explanation. This is a truly ingenious design, not a pure DI and not a pure piston, but a combination of both that works extremely well. It would be very interesting to hear Stoner's thought process when he was designing this.
Watched a many of your bcg physicals. I knew you were checking for efficiency but I didn’t understand how before now. Probably the single biggest learning moment of my gun owning life. Thank you for the content.
I was just looking for vids on BCG when I came across this video. This video was such a good visual learning experience. Thank you so much for this way of teaching, with cutaways, efficiency gauges, etc. I wish more vids could be like this.
What a great vid! I have been troubleshooting a bolt related problem and stumbled on your explanation. You have expanded my understanding and it's greatly appreciated!!!
I learned a lot about the particulars of each component within the BCG and how darn complex these things are. I also appreciate your recognition that tolerances on different parts can be matched in a complementary fashion to yield a well-functioning gas system.
Absolutely FANTASTIC video!!! Been goofing around with and building these things for 30 years and like many others commented already, I’ve learned more in the 20min of their video than 30 years of tinkering and reading! 👍👍
All the system is very clever and i have to say that the bullet also is important part for the gun mechanism to work properly, i mean the ammount of gunpowder in the bullet.
When I was at school for the airlines, I could read something 20 times and kind of get it. But whenever they took us into the aircraft and showed us things that’s when I really got it. Definitely a visual learner.
Sir, I appreciate the detailed description on the gas and how it works... The years it took to get the intuitive knowledge of that specific device astounds me.. I applaud you... Job well done.!!
Very cool thank you for sharing this! I love cutaway’s, not only are they just plain cool but I also find it a bit easier to understand operation through a cutaway vs something like a 3D diagram.
Thank you! I'm one of the visual types. When trying to follow discussions (arguments??) about 'internal piston or DI', I had trouble visualizing how the BCG actually functioned as a piston. This video really helped.
Stoner was an absolute engineering genius genius! Thank you for this video. And sharing your genius with the explanation of the engineering that's involved within the AR15 .
Brownells used to carry a one piece gas ring set. I haven't seen them in some time. I used to use them all the time and gas ring wear was not as much of an issue as it could get on hard run guns. Loved this cut away vid, it visualized perfectly how I understood the process to work. Great for those that are new to the DI Ar15 system!
This is an outstanding video. Thank you for taking the time to teach us with the cut aways. I was a unit armorer when I was in the Army 40 some years ago and I am always learning 😊 All the best, Norm in Arizona
After watching this nobody with basic mechanical understanding should be calling the AR a direct impingement weapon anymore. In Eugene Stoner's words it is an internal piston system and I wholeheartedly agree.
Thank you so much for breaking this down. Gunsmithing is amazing, but more so the knowledge in what's actually going on is so important, thank you again.
Awesome, detailed explanation. Rebel looks like an awesome kitteh too. I keep delving deeper into your catalog of info. Thank you for making the world a little more intelligent with every day. I like to learn at least one new thing a day and you help me with my goal. Appreciate you folks. 🤙🏾
This is the most informative vid ive ever seen on the BCG. I just recently replaced my rings on my 10.5 with a fixed 5" brake. Was having issues and when i disassembled it, the forward most ring was broken in 2 pieces. I got curious before reassembly and put one down with 2 rings. It worked. Great teaching good sir. Im subd.👍
You Sir are THE Go-Too Instructor for this particular rifle platform, if anyone wanted to take such into the professional repair/commercially oriented build spheres youre classroom courses is def the place to do so... -Happy New Year to y'allz...;)
I just happened to stumble upon this channel and I’m SO glad I did. I love all this technical stuff and it helps to understand our rifle platform better. I wish I could get a set of all those gauges and check out my own rifles, but I don’t know if they’re available, and I’m guessing they wouldn’t be economical to someone who only owns a few rifles and doesn’t do this for a living, even if they are. Please keep making your videos, because they are fascinating, and even without your specialized tools, you’ve taught us that there are a lot of things an owner can inspect and watch out for in our own rifles. Thank you.
I was KP the day they explained a lot of this stuff. I had to ask other guys a lot of questions. I survived. Brings back memories keeping this bolt clean, or else.
Another one of your incredible videos. I will definitely be sharing with anyone I know new to the AR. 👍🏻 I wish your videos were around in 2007. I could’ve saved myself a lot of time. Thank you for taking the time to share all of this info with us.
Yes this is very cool and I think good to understand. The cut outs really show functionality and makes me realize how smart the people were that came up with the AR platform. To not only come up with the concept but to get everything designed and timed just right for it to work perfectly is mind blowing. Too bad your classes are not closer to the West Coast. Great job on the channel.
You sir have a very nice channel. I work listening to your videos and also watching them after work. For a beginner AR-15 owner like me diving into details of how it works with such a great explanation is just remarkable. Greetings from Ukraine.
Really appreciate your videos! One SIMPLE thing I picked up on in this video is your Armour's bench pad. I use the long rifle version of bench pads with those fancy diagrams on that cost $20‐$30. One, they're never big enough of my bench and work area. Two, I go through like 2-3 of those per year. That pad you have looks like those one you can buy at Harbor Frieght for a few dollars for a whole pack and are like 2'x2' in size. Dang!!! That's genius, son! I can link & cut as many as I need for my Armour's bench and replace for a fraction of what it use to cost me. Aahhh ... the simple things in life. THANKS!
Great video! I’m now a subscriber. Everyone who operates one of these should know at least some of the how’s and why’s of the firearm. They are pretty complex and the more we know could save us time, money and maybe a life. Thank you for sharing!
Absolutely the best video ever!!!!!!!! Thank you so much for taking the time to make this video!!!! I put an aluminum bcg in my 3 gun ar and it had problems after around 20 rounds or so so I bought a mill spec bcg changed JUST the bolt and it has ran flawlessly since then!! THIS video gives me starting tools to figure out what dimensions I need to start checking to find out why it did not function!!! And so so much more!! Thank you again for making such a detailed video!! Best wishes for you!!
I've learned more about the AR platform from SotAR than in my 24-year military life dealing with Small Arms. The explanation of the gas function as it pushes the bolt forward has completely changed my visualization of the firing sequence. Thank you and glad to see Rebel again.
If only I could have seen this 35 years ago, I would have actually understood why it functions. Thanks!
are you Ashli babbitt?
All these videos are priceless
Worrying that a soldier didn't understand guns.
This is a cool video but I don't know how you would not know and understand all this with a 24 year military career dealing with small arms lol
Found it educational and just plain cool. Those cutaway's are awesome.
This is the way
I've built probably 20 ARs from various parts and kits but every time I click one of your videos I still find myself extremely humbled.
Absolutely a genius design. The sort of thing you see in a dream after decades of obsessive passion over a subject.
Some people think with words, some of us think in pictures. This sort of thing is extremely helpful to me for understanding how things work.
This is just amazing! I sometimes take for granted just how much engineering has gone into the BCG design. So cool to see how it functions via the cutaway. Thanks for posting!
That cutaway is incorrect?
Despite having learned a good bit about the mechanics and intricacies of the AR (a good bit from your videos) I was still able to learn a new thing about the pressurization in the BCG taking load off of the bolt lugs, thus prolonging their service life. The content you put out is simply astonishing and the internet and UA-cam don't deserve you.
That was new to me also. This is the best on the web.
As a visual learner/understander…this is fantastic. Thank You!
God this video is SO cool! I LOVE all this nerdy stuff about the AR, I absolutely love the process of when, where, and why you test! Please don't ever stop this train Mr. A! All the testing and info you provide for the community, might I add for (FREE) here on UA-cam is invaluable! Thanks for all you sir!

The first demo of the carrier was great....
The cut out rifle was even better....
The Annology was one of the best I have seen.
Outstanding!
GREAT VIDEOS FROM THIS SCHOOL...!!!!!!!
This is absolutely the best video I’ve ever seen on the Mechanics and Theory of AR operation.. those little bits of gold like a beat up bolt retainer pin = tail shaft leakage.. amazing. This video should mandatory in Basic Training for all military branches. I know they aren’t Armorers but they know the how and why. Thank You brother for such amazing content!

I thought I understood everything about the operating cycle till I watched this video. Sharing such great educational information with the public makes you a true patriot.
Great video with very clear views and valuable information. And the guest appearance of Rebel was a nice surprise.
Semper Fidelis 🇺🇸
So glad you mentioned the gas rings lining up. I remember learning that in boot camp and always thought that was a necessary check. Also didn't know the gas rings compressed as they're put in the BCG
Bravo, la meilleure méthode pour comprendre le fonctionnement d'une arme automatique. Merci.
Amazing content. The firearm cutaway is what happens when skill, understanding & passion meet: a work of art. Seriously.
Thanks for your dedication to sharing your knowledge. May you continue for as long as you wish. Liked how Rebel answered when spoken to. 😎
Fantastic video. I really appreciated seeing how the gas traveling behind the bolt starts the process of unlocking it!
This is an INCREDIBLE video. Your wife hit a home run with that Valentine's Day gift. No amount of cartoons or animation will show as clearly how the bolt and bolt carrier interact during firing as you did with the actual metal parts. Now I know exactly why the bolt tail is always caked with carbon, and I also know that I probably need to do a better job cleaning the inside "chamber" of my BCG that is hidden so it's "out of sight, out of mind". Thank you for this.
No apologies for the interruption needed. After all, his name is Rebel. Been a sub for... idk, a couple years. I love learning & gaining better understanding. You can't get this level of information anywhere but here. Thank you for doing what you do and doing it so well! You know you have serious students when there are zero dislikes!
Very cool video. It was very cool to actually see a cut away of the inner workings
I had a good idea of the BCG's operation inside the weapon and that cutaway along with your explanation confirmed it! thanks Chad... good to see Rebel again too 👍
This is even more clear than those cut away graphics videos showing all the intricacies. It's kind of like photography and football. You can learn a lot by just watching videos like that but you really have to have someone who understands the thing well to explain it properly.
I’ve been saving this until I was done compiling. This video is my relaxation for the week. Thank you
When I was learning, I had so much trouble figuring out why the rifle wouldn't cycle. I LOVE videos like this, they help me understand the mechanics of what's happening so I could better diagnose the issues. Thank you!

Really interesting to watch this deep dive into the AR system. It further exemplifies how polar opposite the design ethos was between the M16 weapon system and the AK47.
I'm one of those guys that learns by seeing it all first hand. Seeing you take the time to do some educating like this brings me joy my dude. Thank you.
I feel like this UA-cam channel saved me thousands of dollars by taking the AR class from SDI. Thank you for your service on here.
I really need to remember what you said. I wished I was watching this while I have my ar open up for cleaning/oiling. I liked your parts. Your video just popped up. I am going to subscribe. I love your cat.
This is a GREAT video and shares more knowledge in 20 mins then most ever! Thank you so much for all you do!!
Of all my time working on AR's I never made the connection that the same pressure that pushes back on the carrier also pushes forward, relieving some stress on the lugs...
Best educational channel on UA-cam. Hands down.
I agree. "Learn something new each day" my dad would say, and I did. Great Video!
All bcg parts are extremely complicated to be machined.
Are they originally casted in production?
Or how were they made?
So after watching this detailed demonstration, I learned something that I never thought about. Which is, the gas pushing/making forward pressure on the gas rings and bolt. You say that it removes some of the load from the lugs but wouldn’t this also help with the unlocking? The gas is pushing the carrier rewards but since the gas chamber is also pushing on the back of the gas rings creating forward pressure on the bolt, this should also help the cam rotation!

A thousand thanks for putting this together .
Absolutely the best video I’ve seen on the gas system. When piston conversions for ARs first became a thing, and were all the rage on fanboy websites, I tried to explain the disadvantages I saw, including increased bolt lug wear, but was shouted down by the mobs.
BTW, you’re a great teacher as well as being extremely knowledgeable.
I've been looking for a video that uses AR-15 cutaways for ages...finally found yours. What a great job of explanation, too. The visual of the cutaways with your explanation makes all the difference.

The cutaway with the gages was fantastic! Connects the dots on what’s happening, also shows value in your gages, nicely done!
The guy who got me into shooting at the range always insisted AR-15s are horrible because they throw gas into your action and i couldnt believe it was that stupid because so many people (and militaries) use it. This video properly showcased the reason, the up and downsides and the inner workings of the AR action. truly, a very nice video and a great piece of teaching equipment.
I'm watching this long after the fact but thank you for the visual and explanation. This is a truly ingenious design, not a pure DI and not a pure piston, but a combination of both that works extremely well. It would be very interesting to hear Stoner's thought process when he was designing this.
The cleanliness of your fingernails is both amazing and humbling. That cutaway bolt carrier is gorgeous. I want one!
I haven’t watched a video one of yours that hasn’t blown my mind in comparison to what I thought I knew about AR’s.
Love it!
Thanks for such a clear explanation. I'm no gun smith, but I love knowing about exactly how my machines work.
Watched a many of your bcg physicals. I knew you were checking for efficiency but I didn’t understand how before now. Probably the single biggest learning moment of my gun owning life. Thank you for the content.
Man this channel is such a great resource. You guys are incredible. Awesome job 💯

Very educational, thank you! And yes EDM is amazing on how precisely the cuts are.
I have learned more about bolt carrier function in your video than I would have ever suspected. Excellent presentation. Thank you.
Really cool to see a physical demonstration and explanation of why piston systems are not > than DI ones. Awesome video, thanks for sharing
Sir, I appreciate the detailed description on the gas and how it works... The years it took to get the intuitive knowledge of that specific device astounds me.. I applaud you... Job well done.!!
Because of this video we diagnosed a problem, fixed it.
Now the works good with all ammo!
Amazing video, thanks for sharing your knowledge
Very cool thank you for sharing this! I love cutaway’s, not only are they just plain cool but I also find it a bit easier to understand operation through a cutaway vs something like a 3D diagram.
Thanks for making this video, this is a great way to explain the full operation of the system. Also very cool to see cut-aways!
Thank you! I'm one of the visual types. When trying to follow discussions (arguments??) about 'internal piston or DI', I had trouble visualizing how the BCG actually functioned as a piston. This video really helped.
I send this video to all my military friends. So they can see the operation of their weapon. Thanks. Perfect for some people
Stoner was an absolute engineering genius genius! Thank you for this video. And sharing your genius with the explanation of the engineering that's involved within the AR15 .

All the best,
Norm in Arizona
The tools that you assembled are great. As soon as I have room...yeah. I am grateful for the lessons.
I never knew about the high tolerances inside one of these things. Thanks you for your amazing teaching.
After watching this nobody with basic mechanical understanding should be calling the AR a direct impingement weapon anymore. In Eugene Stoner's words it is an internal piston system and I wholeheartedly agree.
Thank you so much for breaking this down. Gunsmithing is amazing, but more so the knowledge in what's actually going on is so important, thank you again.

-Happy New Year to y'allz...;)
This is the most important channel for anyone who owns an AR-15
Agreed.
I just happened to stumble upon this channel and I’m SO glad I did. I love all this technical stuff and it helps to understand our rifle platform better. I wish I could get a set of all those gauges and check out my own rifles, but I don’t know if they’re available, and I’m guessing they wouldn’t be economical to someone who only owns a few rifles and doesn’t do this for a living, even if they are. Please keep making your videos, because they are fascinating, and even without your specialized tools, you’ve taught us that there are a lot of things an owner can inspect and watch out for in our own rifles. Thank you.
Magnificent training tool. Thank you for taking the time to show this and explain.
I was KP the day they explained a lot of this stuff. I had to ask other guys a lot of questions. I survived. Brings back memories keeping this bolt clean, or else.
That bolt carrier cutaway is *awesome!*
I didn't grok how the AR _actually_ worked at all till I saw that.
Another one of your incredible videos. I will definitely be sharing with anyone I know new to the AR. 👍🏻
I wish your videos were around in 2007. I could’ve saved myself a lot of time. Thank you for taking the time to share all of this info with us.
What an incredible video. This is easily one of the very best, most informative pieces of content for the AR15. Well done.
Yes this is very cool and I think good to understand. The cut outs really show functionality and makes me realize how smart the people were that came up with the AR platform. To not only come up with the concept but to get everything designed and timed just right for it to work perfectly is mind blowing. Too bad your classes are not closer to the West Coast. Great job on the channel.
You sir have a very nice channel. I work listening to your videos and also watching them after work. For a beginner AR-15 owner like me diving into details of how it works with such a great explanation is just remarkable. Greetings from Ukraine.
What makes these videos valuable is everyone can learn what to do but few know the REAL why and you get that here.
Subscribed immediately after watching your videos - they are so informative on a level I've never seen before!
Love the shop cat!
Great Viedo. I always learn so much watching how you analyze analyze the various systems.
The cutaway is awesome.
Thanks 😊
Really appreciate your videos!
One SIMPLE thing I picked up on in this video is your Armour's bench pad. I use the long rifle version of bench pads with those fancy diagrams on that cost $20‐$30. One, they're never big enough of my bench and work area. Two, I go through like 2-3 of those per year. That pad you have looks like those one you can buy at Harbor Frieght for a few dollars for a whole pack and are like 2'x2' in size. Dang!!! That's genius, son! I can link & cut as many as I need for my Armour's bench and replace for a fraction of what it use to cost me.
Aahhh ... the simple things in life. THANKS!
What an incredibly well designed system.
As a new AR armorer your videos are incredibly valuable. I appreciate all the work that you do to help me learn in addition to my training.
Great video! I’m now a subscriber. Everyone who operates one of these should know at least some of the how’s and why’s of the firearm. They are pretty complex and the more we know could save us time, money and maybe a life. Thank you for sharing!
Thank you. Awesome demonstration
Absolutely the best video ever!!!!!!!! Thank you so much for taking the time to make this video!!!! I put an aluminum bcg in my 3 gun ar and it had problems after around 20 rounds or so so I bought a mill spec bcg changed JUST the bolt and it has ran flawlessly since then!! THIS video gives me starting tools to figure out what dimensions I need to start checking to find out why it did not function!!! And so so much more!! Thank you again for making such a detailed video!! Best wishes for you!!
Good video, very instructive. Thanks for making it and Rebel should get an extra cat treat for his cameo appearance.
Very very interesting, I finally understood how the AR system works, many thanks for the clear and precise explanation.
Everyone needs a shop cat!
Great explanation! Thanks for pointing out things I wouldn't have thought about if my AR starts acting up.
Your video reaffirmed what my minds eye saw. Thank you much.
