Serious question: would it be beneficial to use a new roll pin/coil pin when reinstalling the ejector? Won't the old pin be loose? Also, anyone know the size and length of that ejector roll pin?
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.
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.
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.
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.
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.
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
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
Thanks for the nice comment. And thanks for watching the video! I typically just buy parts as needed. I have more than one AR so I am never without one!
Loved the video; watched this before doing mine. Question though - if you have that base gadget, then how can you know the joy of having some spring bounce to parts unknown?
And I think I need that little holder-block. You're using it so I presume it makes life much easier. Really hard to hold the bolt while you do off - center tapping.
I want to change the extraction spring but by the gods the PIN won't come out. I saw you did with almost no effort at 1:10 but mine it's like it's solded. Any tips? Yes I'm using punch pin tools. Great video by the way, very helpful.
Mine was a pain in the ass to change. Maybe depends on tolerances and/or how many rounds have been on it. This vid showed it easy, mine was very difficult lol
Im getting failure to eject only some times causing big malfunction trying to feed new round with brass in extractor. This is with BCM extractor Spring and o ring. Wondering if it could be ejector problem although seems fine and is relatively new. Or maybe too much extract spring ? The new spring and or big did fix extractor problem with steel case
If you have good tension on the ejector it probably is not that unless there is something in the ejector channel, causing it to bind and maybe occasionally get stuck.
At 5:28 when you reinstall the extractor, what keeps the extractor spring in place? Mine separated itself from the extractor and wasn't happy about going back into place.
John, thanks for watching the video! The spring is basically held in place by the extractor when assembled, and friction when disassembled. Mine was tight enough that when it was disassembled, it stayed on the extractor. Did you get it back together ok? Dave
@@davesgunchannel Yes! And wow, a personal reply within 24 hours, thank you. Took it to the range today and it works perfectly. It turned out to be just as well that the spring popped out on disassembly - it was dirty in there (that might be why it came loose). Solid A+ for you, Dave, on the video and the quick answer.
The little rubber o-ring Goes over top of the extractor spring. It is usually an optional part that improves extraction performance by increasing the spring tension. Not all bolts have one.
It increases the pressure the extractor puts in the rim. It was part of the M4 upgrades called an extractor booster. You don't need it, but I'd say run it
Funny trick my dad taught me that I thought was complete BS but actually works.. Build your rifles in the bathtub while sitting on a chair with the curtain closed and the drain plugged to learn the first time. If you are surprised with a spring or detent... It's contained and hasn't been shot to oblivion Lol 😅
@@davesgunchannel truth be told the first lower I ever did I sent the forward retaining pin detent and spring into another universe lol then he told me to do that.
No, the extractor does not need to be removed to get the ejector out. Also, it is best to replace that roll pin when reassembling of possible, but I have reused mine before and not had any problem. I would say if you shoot a whole lot of rounds then it’s probably a good idea to replace that pin
Serious question: would it be beneficial to use a new roll pin/coil pin when reinstalling the ejector? Won't the old pin be loose? Also, anyone know the size and length of that ejector roll pin?
Great video. I have purchased a 2nd hand rifle that is not ejecting shells. When i attempt to remove the ejector pin it wont budge. the ejector is also stuck fully depressed flush to the bolt face. Is there a recommendation to help me remove such a stubborn pin?
Kyle, sorry to hear the trouble you are having. Maybe try soaking that in WD-40 or a low viscosity penetrating oil for a while to try to loosen things up? Dave
So I got my ejector apart the cross pin (you removed it first) is broken and cut into little tiny pieces.. any suggestions on why that might have happened??
I would just wipe it with a dry cloth, or use some solvent if real dirty. Clean the spring same way and use a pipe cleaner to clean the extractor channel in the bolt. Also watch this video: th-cam.com/video/VQnn-LTMqBg/w-d-xo.htmlsi=QFpgGNHV587m6FAt
Do you use a new ejector rollpin after each disassembly or do you reuse the old pin? I hear a new rollpin often recommended by gunsmith types. Also, have you tried applying tension on the ejector during reassembly by leveraging a shell casing into the bolt face via the extractor? Appreciate the vid!
Great comment! I use the same roll pin but I would probably replace it if I had some laying around as a Gunsmith would! Your idea for tensioning the ejector is a good one, I will definitely use it next time, thanks!!
Just to add my two cents as an industrial maintenance guy. You always replace the rollpin if you have some laying around as he said, but at the end of the day unless there's something wrong with it (i.e. it's been really worn down from constant removal or it's deformed), the pin is gonna do it's job. It's just a piece of metal there to stop some thing from falling out.
My punches are a different brand, so I cannot comment on that. I know my other Real Avid tools are very well made and have stood up to a good amount of use. Thanks for the question!
Thanks for the info! I only asked about those two brands as they were the ones listed and linked with the video. Do you know what brand they are and are worth the time to lookup or would you recommend a different brand?
Yes, that is an optional part that helps the extractor work better. I would keep it there but it is not absolutely necessary unless you have issues with the rifle extracting reliably. It adds tension to the extractor to give it a better grip on the brass.
Not all extractors have the O-ring. It is an extra part that increases the tension on the extractor, theoretically improving reliability of the extractor. Thanks for watching the video! Dave
I have an AR10 and needed to check headspace. unfortunately the pin for the plunger split open when I tried reinstalling it. Do you know the dimensions of that pin, or how I can order it? it really annoys me how rolls pins are used in AR's its like they safe 50 cents and its a terrible product.
Thank you for the question! It seems that opinions vary on this, I wouldn’t worry about it unless you remove it several times then I would replace it. Dave

This was super helpful. I had to hammer that pin back in though. Mine didn’t go in that easy

Thanks! I did it to show how it’s done. Never had a problem so far! Thanks for the question!
Dave
@@davesgunchannel
Thanks for the quick reply.
IF you left the extractor in, how would that screw up a headspace check with go/no go gauges?
From what I understand, it can give you false readings. You also should clean the bolt and bolt face before head spacing.
Thank you
Funny trick my dad taught me that I thought was complete BS but actually works.. Build your rifles in the bathtub while sitting on a chair with the curtain closed and the drain plugged to learn the first time.
If you are surprised with a spring or detent... It's contained and hasn't been shot to oblivion Lol 😅
Doubt I will try that but the theory is sound!! I appreciate the input!
@@davesgunchannel truth be told the first lower I ever did I sent the forward retaining pin detent and spring into another universe lol then he told me to do that.
@@deadlysrestorations LOL. I have spent many hours searching various rooms in my house as well. So far, I have managed to find everything I launched!
Is that roll pin 3/8” or 7/16” long? I see different things online.
Do I need to take out the extractor to be able to remove the ejector? And can I reuse the ejector roll pin or is it a single use pin?
No, the extractor does not need to be removed to get the ejector out. Also, it is best to replace that roll pin when reassembling of possible, but I have reused mine before and not had any problem. I would say if you shoot a whole lot of rounds then it’s probably a good idea to replace that pin

Serious question: would it be beneficial to use a new roll pin/coil pin when reinstalling the ejector? Won't the old pin be loose? Also, anyone know the size and length of that ejector roll pin?
Yes, it is best to replace it but not always necessary. I will check for the size of the pin.
Great video
Thank you very much!
How often do you need to clean these? How do you know when it needs cleaning?
It’s recommended to clean it after each use, that will make it super easy to clean each time.
excellent Clear
Thanks! I appreciate the comment!
Great video. I have purchased a 2nd hand rifle that is not ejecting shells. When i attempt to remove the ejector pin it wont budge. the ejector is also stuck fully depressed flush to the bolt face.

So I got my ejector apart the cross pin (you removed it first) is broken and cut into little tiny pieces.. any suggestions on why that might have happened??
Wow, I have no idea! I know those pins can wear out though.
How do you clean the extractor ? Do you remove its spring ? I'd like to get a spring co spring.
I would just wipe it with a dry cloth, or use some solvent if real dirty. Clean the spring same way and use a pipe cleaner to clean the extractor channel in the bolt. Also watch this video: th-cam.com/video/VQnn-LTMqBg/w-d-xo.htmlsi=QFpgGNHV587m6FAt

My ruger ar15 5.56 nato has a rubber washer around the extractor spring is it supposed to be on it i don't see anyone else's with it.
Yes, that is an optional part that helps the extractor work better. I would keep it there but it is not absolutely necessary unless you have issues with the rifle extracting reliably. It adds tension to the extractor to give it a better grip on the brass.
what specific size of extractor pin?
Thank from Ukraine
Awesome! Thanks for commenting!
what size is Extractor pin?
Why wasn't there a rubber gasket on the extractor spring??
Not all extractors have the O-ring. It is an extra part that increases the tension on the extractor, theoretically improving reliability of the extractor.

How Often do you need to Do This ? How Many Rounds ?
Almost never. You might pull the extractor every 5,000 rds or so and clean, but the ejector will be fine.
My buddies pin wont come out to release the extractor. Help!!
Try soaking it in WD-40 for a while.
