- Everyone asks where I find AR-15 stuff in stock or where I order from, so here you are: bit.ly/2trc7Kg
-----------------------------------------------------------------------------------
In this video, I explain why it is important to stake a castle nut, and then show and explain how to remove one. Staking a castle nut on an AR-15 is per "mil-spec" and is considered semi permanent.

Two minutes of intro just to tell me to unscrew it...
You took the words right put of my mouth.
Heh….If you needed to know how to pop off a staked castle nut then this was ALL beneficial information for you. Hopefully you re-staked the new one, and continued learning your way around your AR these last 4 years instead of letting it collect dust. Take care of yourself.
Bro I was thinking the same shit after all he did was just unscrew it
Fr, I saw your comment before the video started
I miss the dislike option
I cannot begin to list all of the vids you have done that have helped me with specific issues. KEEP UP THE GREAT WORK!
Thank you, sir! By the way, it was great to meet you at SHOT :)
Same here!
Watching your videos have given me the confidence to dive in headfirst and do the installs myself! Keep up the excellent vids
Awesome! Just remember to have fun :)
You are very welcome. I didn't think that 3 minutes was very long. I guess some people don't have the patience for even a 3 minute video, but then take 4 minutes to leave comments with a poor attitude. Thanks for having my back :-)
I’ve watched all your vids. You are one of if not the most knowledgeable guy on TH-cam with ARs. I’ve built over 75 of them and still look to you for info. Thanks for all these vids man. Great job
You may be surprised how easy it is to do a lot of the stuff that gunsmiths get paid to do. Make sure and check out my other videos as well. I show you exactly how to do a lot of things yourself. Thank you for watching!
Awesome awesome info I'm putting on a magpul ubr and didn't know if I'd run into to any issues with my Castle nut this has helped tremendously
Thank you for the video 9 years later and it still helped me
Humm, unscrew the buffer tube (not shown in the video) and ......
Whang!!! out comes that pin that keeps the buffer spring in place with its little spring, and about 90 miles an hour, apparently headed for space. After a half hour search I found both parts.
Moral: When unscrewing the buffer tube, hold on to that little black pin.
It's especially fun when that little black pin flies into the 1970's era black shag carpet!
Critical bit of information
word of warning: If you camp down on the receiver, when you unscrew the castle nut and the castle nut is very tight, you could very possibly STRIP the buffer tube. This happened to me!
Here's how it could be striped: IF the force required to unscrew the castle nut is HIGHER than the force required to strip the indentation on the bottom of the buffer tube WITH the retaining plate, then the little notch on the retaining plate will ABSOLUTELY rip out from the that little indentation on the buffer tube.
To avoid this, take the upper completely off and clamp down on the butt stock.
You have been warned!
Doing mine tonight and was wondering about this, thanks for the assurance
I fucked my buffer tube up because my new ar15 was staked, I didn't know, and assumed I could just unscrew it. Lucky I got it off and already had a new buffer tube to put on
Thank you. I worried about this as my AR has a staked castle nut and I'd like to put on a sling mount.
Quick and to the point. Exactly what I was looking for! Thanks for doing a quick, informative video.
Thanks! You are welcome and thank you for watching!
Thank you for the very detailed video, you made it a simple task. Along with your staking video, it is now done correctly. Just how it should be.
Burgh 52 You are very welcome!
Thanks for the help. Im new to ARs but not in shooting. I saw my PSA lower has been staked and thought it was going to be a big deal.
If anybody is wondering im replacing the stock tube to a anti-tilt tube and a H3 buffer system for my Wolf A1 upper. Its over gassed and rips the brimming right off the shells.
You are the best gun builder in the world. I mean that. I have built two riles following along. THANK YOU!
Haha, yes indeed they are, but it looks like some of my subs took care of them. As always, thank you for watching.
You are welcome! Thanks for watching!
There were some other people that mentioned that on arfcom. For learning purposes, can you tell me what went wrong and how you stripped the buffer tube?
I would say the reason it busted free easily for him was because the staked material from the end plate was so brittle due to how much material was shaped into the notch that some simple elbow grease was gonna be enough to break it free. Either the end plate or the threads on the buffer tube or castle nut will give up.
Thank you, sir!
That was exactly what I needed thanks!
BlueCollarGear Happy to help :)
thanks for the quick information!
I use a small Dremel tool with the thin grinding disk. As part of my extensive tool collection. LOL. It works really nice and it's a clean look. It also makes re staking a little easier and has a clean look for the next time. 🐢🇺🇸👍
THANK YOU I almost forgot I have a dremel with a very thin grinding disk that would work perfect I didn't even think of it.
I know this was posted years ago, but look into PWS' ratchet lock caatle nut and end plate. Truly innovative engineering.
I'd like to add one of those to my hobby tool box for future builds . thanks for info
Great information I learned something,Great video as well.
You can take a flat punch and push some of the metal of the end plate back away from the Castle nut notches. And i try to get a new end plate to make it look good. Not all buggered up.
Good video Nate!
2 stakes are actually per mil-spec. With a Magpul ASAP, one can only stake once because of the shape.
I was able to get 2 on mine guess i was lucky as hell lol
Usually that works, but one time I had to use a pin punch to push the material back in the other way because it was just stuck that bad.
nice work brother. God Bless.
I hear you about the OCD thing. Weird things fire me up like that.
Agreed.
Try that on a DPMS lower and destroy your buffer tube and castle nut.... There are companies that stake in castle nuts so deep that it is close to impossible to get them off properly w/o hurting parts on the weapon.
You are one of the ppl that i watched a lot of when i started building ARs.... around the time when u made this video, 9 yrs ago. Thanks 🫡
Nice!
Good video about how to loosen the castle nut but what else I would like to see is how to properly hold your firearm while you are wrenching on it.
What to do, what not to do,,,,
I have an AR15/.45 that takes Glock 21 mags and I havn't been able to find anything on TH-cam a bout this kind of set-up
Thank you, trees!
THANKS MAN!!!! IT WORKED!
I got to bring it up an poke some fun being a few videos you mentioned keeping it mil-spec. But your rail isn't, your trigger isn't, your pistol grip isn't, your bolt an carrier isn't. Lol she's a pretty sweet safe queen but slightly mil-spec really if any besides a couple staked things. Great videos. Just couldn't help but to point that out
I just put the wrench on the castle nut and started to turn and the buffer tube and the nut turned together. So the key in the plate ended up striping the keyway grove on the buffer tube. I have no idea how it happened but it was a very costly mistake. I don't know why the mil-spec key and keyway are much smaller than a commercial one...you would think it would be better having a larger key on the plat and a larger keyway on the tube.
Yeah, My BCM wouldn't nudge, even with a hammer to the wrench. Had to dremel it. Installed a PWS buffer, no stake required as it "ratchets" on.
That is a nice extension. Same type I'm looking at. I hate polymer
I've taken them off it wasn't to bad.I had a commercial tube staked on and changed it to a mill spec .
very helpful. thank you.
can you please tell me what brand your wrench is. thanks for the vid keep um coming
now that u have "broken" the old stake, can you re-stake using the same end plate? if so do u have any ideas on how much the plate has been weakened by staking the same piece twice?
Heads up unless you got a heat gun I would not the loctite the castle nut.You'll end up needing a new tube, end plate and possibly a castle nut.
I tried to remove my castle nut that was installed with blue loctite and by the time it budged the buffer tube thread was gouged underneath.
Because it was so bonded on that it turned with the castle nut and overode the end plate area that interfaces with under the tube!
A heat gun helps loosen up the loctite before you remove. A mistake I learned the hard way.
Hand tightened with a armorer wrench is good enough as snug as you can get without stripping castle nut .
And if your keen on using blue loctite a tiny bit goes a long way literally 3-4 small drops where the castle nut is gonna be on the tube your welcome 👍🏼.
It is indeed a Spike's Tactical, but it has already been reserved for MrAK47Master if I decide to sell it.
Just took mine off a brand new DB15 without a vice grip like you've got... had to use a hammer and some Ju Jitsu tactics. Let me say, i'm proud to be American.
Thank you!
Not too keen on just wrenching it, especially when more than one position is staked. Using a small SHARP chisel with the flat side towards the receiver you can CAREFULLY cut away most of the stake without damaging the surrounding parts. Then using a wrench for that final bit. TRY IT, and if you find it works for you too, might consider redoing this video.
I twisted my buffer tube now my pa15 won’t shoot know what’s wrong?
If you shoot hundreds of rounds monthly staking the castle nut makes sense. If you don't shoot that much add a drop of Loctite blue, torque to specs and you're good.
I think they make a fixture to hold the lower in a vice wo marring it up
May i ask what castle wrench that is? Trying to get one that isnt to expensive but actually works haha
What type of vise block you using to keep the lower static?
Are there different size castle nute on Ar-15's? or ar-10's? i ordered a castle nut wrench,i got it today and it is too small to fit my castle nut?
I was going to remove one on my ar to include a qd plate but found a ratcheting castlenut with a qd plate included.
Thanks Bro.
I do not see why you would not be able to re-stake and use the same one. Because of my OCD, it would bother me too much to reuse the old one so I got a new one.
Sorry if this was asked already, what are you using to hold the lower receiver?
After I remove my staked castle nut and change my buffer tube for a new stock can I re-stake the old end plate and castle nut?? Thanks
How do you stake it again after removal? Won’t there be no metal left to stake?
That gray dry film lube comes off with chlorinated brake clean
Try unstaking a spikes tactical castle nut on a lower they assembled.
I'm more interested in the Full auto trigger :)
Most impressive part is the detent spring didn’t fly across the room
Can you then re-use / re-stake that same end plate? Thanks!
How did you clamp your lower on the vise. Did you use a jig or something?
If you reuse your castle but and the original stakes don’t line up is there any harm in staking a completely new spot?
So once you remove it, can you reuse the staked piece ? Or you have to use a new one and restake it?
Just out of curiosity... How do you RE stake the nut once it has that little dent there? Awesome video...wish I had known about the castle nut b4 my DPMS came unraveled. I carried the M16A2 in the Army but it was full stock so I wasn't even aware of the possibility of misfeeding through castle nut backing...oh well..
Hanomag Shadowfeet I restake it on another notch or just use a new castle nut.
nsz85 using a new castle nut doesn't take the dent out of the end plate though. Has that ever been an issue?
Is that old grey tube a Spikes? If so how much you want for it? Thanks
So basically. Staking a castle nut keeps the gun from coming apart on its own, but it can still be removed by the user for maintenance reasons
How many AR15s have you heard about flying apart because the castle nut wasn't staked?
+FRIGGIN' BROBOCOP ...absolutely zero, I've built a few...tight will suffice just fine...no loctite or staking needed....anti walk pins are a must though...
Just bought a stock Colt LE6920. I am trying to remove the castle nut, but my question before I do is: is my rifle or any AR staked from the manufacturer? Can I just remove the castle nut with the wrench and mallet?
Any tips if the hand pressure and hammer doesn’t work? I have a Delton 316H and can’t get the castle nut off to save my life.
Thanks for the video. Have you thought about using a small drive punch or drift to move the material pushed into the slot by the staking operation back into the end plate? It should help the nut come off a bit easier and put the material back where it was for the next staking operation.
And I used a new end plate to look tidy.
Did you skip the part where you did something to the stake? It looked like some damage was done to it. Or can I just use wrench pressure and the stack will break?
@APG95 don't be a silly goose, he's blowing Sam at the moment. We all know that.
Perfect!
Do you have to use a new piece to restake the castle nut now after removing
Great video dude! Okay, but then is that buffer plate useless after that? In other words, is it true that after you stake an end plate it is only good for that one use and no more builds or applications? Thanks!
It depends on where it lines up with the castle nut. If it snugs down in a different spot you will bee able to reuse it and still stake the nut. If it lines up in the original spor, it needs to be replaced. Hope that helps.
8years later and still helped me out thank you
@@mherrera619 lol
Is that a lmt buffer tube? And do you still have it?
Will removing a staked castle nut damage the buffer tube?
I mean at least how i steak mine I would need to prep it with a hacksaw just at the edge of the backplate and the castle nut before I let loose in it
Man I have an armorers wrench to remove my castle nut on my colt ar 15 so I can install a magpul asap sling attachment anf I can't get my castle nut to budge but I also don't have a vise is there a way to do it with out a vise?
I got so many laughs out of these comments. People are so entertaining.
THANKS
Most solid as fu** factory stake jobs aren't going to come off without that wrench either stripping/slipping off the grooves or bending the wrench for most of these individuals. And if that happens they're going to gouge up their buffer tube, or worse...
Either dremel it down or use a drill bit to grind some of the stake out of the castle nut groove. Then just replace the castle nut and end plate after. They're cheap parts to replace.. . No point in risking damage to the rest of the rifle.
2S1L3NT, that was exactly the information I was looking for- I just needed to validate my intent to drill out some of that material. Thank you!

My Colt is staked 3 times from the factory (3 notches).... have you run into that? And do you use the same method... or is there another way to address multiple stakes?
did you figure out how to remove the castle nut on your Colt? Mine is staked in 4 places and it looks like they had used a press machine to do it, it definitely wasn't done with a punch and a hammer. I was wondering if you found out any tricks or information to help? Thanks
+Dennison Small My Colt was only staked in 2 places and this with a mag well vice block got it off.
Well I just broke my wrench trying to get mine off, thinking I might have to buy a net buffer tube and castle nut and just cut the nut on this one, I destroyed the threads.
Omg God dude I just used a wrench to tighten it fires perfectly fine
How
I stripped the shit out of the threading on the buffer tube on an LWRC, but got it out after multiple tries.
LWRC has no staking on the castle nut.
Can you re-stake it ?
Cool man. I have a few of those grey ones and in my experience the CTR is the only stock that really fits it tight. I actually just ordered a tube kit with the Elusive ST-T2 buffer in it. That with a middy system with a battle comp turns your AR into a real pussy cat.
Good vid
Thank you, it was helpful 👶🇺🇸
And to think, I was going to pay the local gunsmith $25 to unstake my BCM lowers castle nut. Only thing I gotta do is get me one of those nifty wrenches and put some elbow grease into it.
That staking was weak, and fragmented already. My properly staked AR's are well bulged into the grooves, and not broken anywhere. I bought one as a complete carbine from LMT, but the other one I did is even better. Plus I staked 3 spots. The bulge going into the grooves is nice and thick. It even partially formed to the shape of the groove.
Not that I want to take it off, but I was hoping to see how a properly staked castle nut could be taken off. It already has the Vltor tube, but JIC I wanted to go with a rifle tube I was interested in this video.
I'm pretty sure I am stuck (literal pun) with this configuration, and would just go with a different lower, configured the way I want it.
Also I was interested because I was thinking about a different end plate for a sling. I'll hafta go the ten dollars more and go for the troy that fits over the castle nut.
I really don't think the thing is ever coming off without destroying the tube, or cutting the castle nut off with a dremel.
it is taken off the same way. use a cattle nut wrench. maybe a little more difficult if you staked three hole
Thanks!
