A lot of new AR-15 shooters mistakenly believe that you can’t remove a staked AR-15 castle nut but that’s not the case. In this video I demonstrate how it’s done.

Nice video sir! Can you re install this buffer tube again even though you removed it when it was once staked ?
Thank you so much for this sharing this valuable information! You saved me so much time and money!

This is great info. But man. Those BCM stakes blow fat rhino balls.
I dont run every AR company out there. But I know for a fact that both Sionics and SOLGW's worst stakes look better than either of the BCM stakes you showed.
BCM has decent quality; but little things like this along with the fact that they are way overgassed is a deal breaker.
ty!
Great info. I have a buddy who built an AR but didn't stake the castle nut because he was thinking if he ever needs to replace the buffer, he won't be able to. I've told him he really needs to stake the thing and tried assuring him it's not permanent. I own a rifle length buffer so no need for staking or unstaking, but hey, this is an AR video so why wouldn't I watch it?!
Great video, now all I need is a workbench and a vise.
❤️❤️❤️❤️❤️Kurdistan flag ❤️❤️❤️❤️❤️
You must’ve never seen Colt’s staking.. oh well
Short version. Put the wrench on the nut and turn. Done.
Thank you!!!!
An idea for a video subject, how to select a qualified gunsmith or armorer if you dont have the equipment – training, experience, etc.
I experienced a so called gunsmith that was incompetent with the AR platform
Great overview. Is there a video on how to stake the castle nut after installing a new end plate? Searched the library, but could not find.
First time removing a castle nut, was worried I was doing something wrong but it was just on super tight and staked. Thanks.
Thanks! Your directions worked perfectly!!!!!
Great video!! Thanks. I'm definitely less intimidated now.
The BEV block was in the vice correctly, but it is made so the lower will slide on the block like inserting a standard mag, there is even a notch for the mag catch.
For the algorithm
I know that this video is several years old, but did you know that the BEV Block has a specific notch on it to lock in place while in the mag well to keep you from nearly loosing your lower? It snaps in place and releases just like a magazine or at least mine does. Thanks for the instruction.
How would you go about removing a staked gas block? Similar method I assume…clamp down your upper, get an Alan wrench that fits and push hard.
$60 isn’t a cheap tool lol
Well, the AR wrench I picked up at my local dealer isn't getting it done. At least not for me. Excellent video (as always).
And a special thanks for the heads up posts on FB about hard to find items being in stock. That's been extremely beneficial the past week or so!
Just a heads up for those who thought about blue loctiting your castle nut instead of staking get a heat gun it would make life alot easier when removing.
I learned that the hard way! By the time my castle nut budged the buffer tube thread was gouged underneath.
Because the tube was so bonded to the castle nut it turned with it and overode the end plate area that interfaces with under the tube!
Had to replace my end plate and buffer tube. Since then I only hand tightened with a armorer wrench.
As snug as I can without stripping the castle nut haven't had it loosen up yet 1200 rounds down the pipe since.
And if your keen on using blue loctite a tiny bit goes a long way literally 3-4 small drops where the castle nuts gonna be .
You can also heat the staking area a little bit with a torch or heat gun to soften the metal a bit to facilitate the removal of the castle nut!
Well staking seems pretty pointless now
The magpul wrench is the key. Doing it with a normal castlenut wrench is almost impossible.
Currently $80 for the wrench. Can I borrow someone's? Never mind, I will use my sawzall.
im curious ,How can i remove my castle nut without a wrench?
LWRC has no staking on the castle nut.
Great video
Great Video!
Dude. Tighten your vise down lol.
Planning to get off the Colt LE6920 staked castle nut. Was thinking of removing the safety and then clamp it on that portion on the vise with wood blocks and go from there.
Spent $80 on that magpul wrench and it doesn't fit over a pistol buffer tube. Spent another $30 on another wrench and it slips out of the teeth as soon as i put any force on it. $120 in and i still can't get this damned castle nut off lol.
Where is your link for your complete AR build. Thanks
Okay so Step One: Put wrench on gun. Step Two: Turn wrench. I think I can handle that. Oh god, what if I turn it the wrong way?!
Great video, thx!
That’s a nice flag in the back ground
Great video! Informative and straightforward. I'm no stranger to building (well, assembling..) ar's, but little tidbits of knowledge like this are always welcome! Sub'd
Very nice review and always very informative…
I like using the geissele reaction block for the lower reciever, and I like using the geissele reaction rod for the upper reciever.
Do you re-stake castle nut to new buffer tube? I have DD Mk18 pistol and want to upgrade to SBA3 brace. Should I restake??
Currently using vise grips and a hammer to get this thing off
Nice looking flag
Helpful video! Thanks! Is there a link for your Complete AR Build video that you mentioned at 4:32 in this video. Thanks.
The links to those tools is not in the description.
I used Dremel to do it and then threw away end plate.
Yes please oppose gun laws wtf it’s 270k people here you can do that!
Been reading a few forums that suggest a dremel if the staking is heinously tight. That seems a bit ham-handed. What about a hacksaw? I would think (if you were desperate) that a hacksaw would be more precise and less prone to skip all over the nut or tube since you're just following the seam.
