Best how to tutorial bar none. Superb job coordinating video with audio explanations. Also appreciated absence of distractions like music or family pets. For an 80 year old newbie with 10 thumbs, working the BCG can be daunting. Thank you, Sir. You’ve provided a real service! Subscribed and look forward to more content from you.

Thanks for being this clear and concise.

Great video. Really appreciate how you took close up pictures to show the detail. I look forward to future vids from you.

Dude, I love how detailed and simple he makes this. Let's get all breakdowns. You're a hero 👍🏻

I have an AR rifle chambered in 7.62x39 that I need to check the Head Space on before I fire it, so I need to remove the ejector from the bolt to properly use some Go, No Go Gauges. I have never done this before and I've repeatedly been told of all the expensive tools I would need, and you just proved them all wrong with a $15 bench block and a couple of punches. I can't wait to get started thinking of all the $$ you saved me. Thanks a million. Liked and subscribed. GREAT VIDEO.

[beesknees]

wow... thank you so much. I've been intimidated to take the ejector out so I can check headspace on home builds. This helps alot.

[radu]

Great video! The simplest method I've seen demonstrated so far. No vise or special-purpose tools required.

[Matt-yx]

Dont need to at this time, But I've wanted to learn this step. Ran accross it accidently and had to watch. Best teaching methods.

[aviesto]

Thank you for lesson. I used to watch disassembe videos and no one mentioned about ejector pin. And its so small i didn't even see it. Biggest thank you. You helped me so much. I think now its safe to say i know everything about ar-15 bolt system.

[mikedurhan]

Thank you so much for a top-notch video. Unlike so many others, your voice is easy to understand (clear) and there's no music blasting at the beginning and end of your video. Very helpful.

[mikewallace]

Using a slave pin when reassembly is a useful technique. I use this technique on various jobs, assembling machines at work. Also, I have used it on AR 15 lower builds. Very good instruction video... No BS just good info.

[thomasjefferson]

Excellent video! Clear and concise explanation, great close- up videography. Thank you.

[xerravon]

I agree with everyone that said, "best how to on ejector" in fact so far the only video on ejector removal/reassembly! THANK YOU! subbed!

Nice. I had one of my plungers fly out. Using a KAK dual ejector . Since they won’t fix it because they won’t deal with people from Illinois you saved the day.

[MorrisOutdoors]

Something I've never done was fiddle with my bolt itself. I just scrub it and go. I needed to learn how to do this because I wanted to know how to swap the ejectors

[richardgluteus]

Best video out there for this process. Checking my headspace and just what I needed, thanks!

[ueeahh]

Holy cow was going buy a Y/M to check my bolt Headspace this is great thank you .

[mick]

Nice ! Iv got a ejector on a relatively new bcg where it sits low compared to others the ejector is flush or a little higher. This one sits lower. It doesn’t eject now. Just holds the shell

[donape]

Grazie! Video salvavita per i nostri AR15!

[james-imsj]

Yes hold on to it waiting on rebuild kit for my bolt spring went flying never did find it.
