    Walks you through a basic assembly process so you see what all the parts look like, their names, how they work together, and how they go together.
    Next week, will check this out as well. The month has been a horror for me, time-wise. Like my beloved 1911 pistols, and SKS, although it's Chinese, I want to learn about my Bushmaster M4A2. I HOPE it continues my "luck" with all my previous firearms of various brands... some of mine have had their detractors, but MINE have all been 100% since 1982, many brands. I see some Bushmasters have had probs; I hope mine will prove not to be so.

    We'll see, and I am sincerely grateful and appreciative of this thread, y'all's replies and excellent guidance and information the Bushmaster line. I don't know what to say, much, other than THANK ALL Y'ALL. I'm still reading...

    Bushmaster is not alone in that regard. You can pretty much fix what needs fixing. I'd start with making sure the carrier keys are properly staked. You can find plenty of info on this site about what to look for and how to fix it. Also, C4IGrant recently fixed some Bushmasters that he plans to sell. One of his posts (in the last week or so) listed the required fixes, so that thread would be a great resource for you.

    I am currently on your provided link. I have bookmarked it! I'm not going to fire my M4 until I have the time to check it... from the INSIDE. My Pmags are hung up, and Magpull's not responding... BUT: I hope my Bushmaster is sound, or can easily be made so.

    It's a good weapon. I like its feel. Just handling it in my apartment, unloaded, seems real easy to get on target: stock extended to max, I wondered how the "birdcage" sighted on the front sight... the little aperture ring, with the top tang, lines up very quickly on the front sight blade... that's impressive, and nice to me, on the AR15/M4 platform with the birdcage. Good to know that any possible probs with my Bushmaster make, are not hard to fix... I've modified a number of my 1911 pistols, myself. I've also been "won" to the .223 Remington cartridge, in 55 grain FMJ bullet. Or M193 5.56x45 mm cartridge. I was always pretty much a .30-cal guy... and my SKS in 7.62x39mm NATO has its applications in general. But NOW, I think a good .223 is very versatile, if you have a rifle that is solid and reliable.

    I really appreciate the welcome, and the free sharing of guidance, instructions, and information. I'm one of those folks who KNOWS I don't know everything about anything (I work with some who don't realize this fact)... I'm pretty knowledgeable on the M1911 handgun platform, but, there you go: same difference. I like to KNOW my weapons. Inside and out. I want them to work. NEVER want to have to use one defensively, although I HAVE had three armed encounters in my life with bad guys... NOT FUN. And thankfully, no shots fired. The bad guys were smart, in those situations. Thank my powers.

    My power bless all y'all good folks here! I'll let y'all know how my Bushmaster checks out on the disassembly and examination. Thank y'all for helping me.

    Y'all take care and be safe. I'm fixin' to be out of pocket online until end of next week.

    Mick's Bushmaster And Carrier Key Staking

    Check out this thread on carrier key staking, and what a properly staked key should look like: https://www.m4carbine.net/showthread.php?t=6993

    You should be able to do a search on this and the castle nut staking issue for more info. I know that Grant at G&R Tactical, who also belongs to these forums, is a BM dealer and might be able to take care of this for you.

    On the Mag issue, I wouldn't worry about it. I'm not sure how reliable the Bushmaster-brand magazines are these days. About 10 years ago I had one of their 10-rounders (from the Clinton "ban" days) and it was junk. Anyways, just pick up some P-Mags and you'll be all set. As for lube, just use whatever works best for you. Perhaps try a few quality brands that have already been mentioned above, eventually you'll figure out what you like. Some people even use 10w30 motor oil with some success. There are a bunch of other threads on this topic if you want to look into it more. I use Slip 2000 for everything.. Handguns, rifles, shotguns.

    Go shoot your rifle and let us know how it does.
    I've partially disassembled my M4A2 twice, in as many nights... I've got my bolt carrier out and laying here. The Torx screws are TIGHT, but the "pings" to hold them are extremely light. They're there, but like I say... I may contact Grant at G&R soon.

    I don't know about the castle nut. Mine has the adjustable stock, not the AR15 rifle stock. That may be what you're refering to as the "collapsable" one.

    Mags: I've had some probs with Magpul. But, resolved them today. The ones I ordered in OD Green were massively backordered; I switched to Foliage Green. I'll let y'all know how they feed and function in the Bushmaster. My BMI ones will feed reliably just racking rounds through them until empty. But, I'm still working on a place to fire this beauty.

    It's a complicated firearm, for a mostly "pistolero (largely M1911 platforms, which I LOVE for their reliability and simplicity)" like me... but, I'm GOING to learn it, like I'm learning my SKS and like I learned my Mossberg shotguns. I hope I've got me a good one. I'm trying to save all these links y'all have provided!

    Using a FMJ round to disassemble the weapon fascinates me... LOL: guess if you don't have ammo, there's no need to clean and lube! My 1911 Multi-Tool also works for my Bushmaster M4, SO FAR... LOL...

    Y'all take care and be safe.

    Thank you, phoric... Strangely enough...

    See this thread and this one.
    ... after fighting with my connection tonight, and looking at some of your references, my Bushy M4 has NO, repeat, no, staking on the castle nut!

    That's odd. Not necessarily heartening to know, either.

    It's got the three machined rectangular nicks on the side toward the receiver, but the plate it's against is as smooth as black ice all the way around. Not a scratch, not a ding, not a stake mark.

    Bolt carrier aside, next couple of weeks I may contact Bushmaster. I've not had the chance to fire the rifle, as I'm trying to learn all I can about it prior to that initiation; but from your links, looks like Bushy slipped this one by without "finishing" it properly. I'm going to have to study the links you folks have provided here, before I make ANY major decision.

    I'm obviously not in a combat situation (yet, I leave that for individual interpretation), but, still... would be a heck of a thing to got through a couple of hundred rounds and have the castle nut start loosening. As I said, the bolt carrier is staked, but it's very, very minimal.

    This concerns me about the weapon's overall integrity now. We'll see, I guess. I'm not made of money. I don't know.

    SO appreciate you folks guiding me and linking for me. I'm trying to learn.

    Y'all take care and have a good weekend; fathers, HAPPY FATHER'S DAY.

    Actually that is typical Bushmaster. I have 500 of them here and they are not staked except for the ones that I have done.

    I wouldn't bother contacting them. They will give you a Fred Astaire and Ginger Rogers tap dance routine that will make you scratch your head. They know all too well about their not staking of bolt carrier key screws, castle nuts, and all the other stuff that they do.

    I'm obviously not in a combat situation (yet, I leave that for individual interpretation), but, still... would be a heck of a thing to got through a couple of hundred rounds and have the castle nut start loosening. As I said, the bolt carrier is staked, but it's very, very minimal.

    Stake it properly as it will loosen. I have fixed over about 10 here so far because they weren't staked correctly.

    This concerns me about the weapon's overall integrity now. We'll see, I guess. I'm not made of money. I don't know.

    Most of the issues can be fixed by you. Just search the forums here and get a copy of an M16/M4 Tech. Manual.

    SO appreciate you folks guiding me and linking for me. I'm trying to learn.

    Y'all take care and have a good weekend; fathers, HAPPY FATHER'S DAY.
