Remington 870 Tips & Tricks #2: Receiver Stud Replacement & Repair:
This Remington 870 Express Synthetic had its stock bolt forcibly screwed all the way in while cross-threaded, which damaged the threads on the stock bolt, as well as the threads receiving it. On the 870, the stock bolt screws into a separate part called the receiver stud, which can be replaced if it becomes damaged.
In this video, I'll demonstrate how to replace this part, and also show how to repair the stud's internal threads if they are not too extensively damaged.
I recommend watching this video with the annotations turned on. I'll be adding various notes to provide further details, or answer questions you might have. I've tried to keep them unobtrusive; no giant flags blocking the video, no begging for subscriptions or likes.
If you have any questions about this procedure, please ask in the comments below. Like many things in life, guns can be dangerous if modified or used improperly, so make sure you understand what you're doing before you work on yours. If you're uncomfortable trying anything you see here yourself; please get assistance, or just let a qualified gunsmith handle it for you.
This continues my series of how-to videos with the Remington 870 shotgun. There are a number of other topics I have planned for future videos, but it's a fluid list. I'd love to hear any suggestions you might have for video topics. If it's something that has already been covered, I may point you elsewhere, but if it's an interesting and feasible idea, I'll add it to the list.
I'd also appreciate any comments on the format of this series; things you liked, things you didn't like, things you'd like to see done differently, etc. I'm still playing around with styles and programs, figuring out what works well and what doesn't, so any input would help me out.

If the stud is threaded all the way through, why not start your tap from the other side so that you will engage the good thread initially and will be sure that your tap is not damaging the good thread. It will then start cutting when screwed in much further and starts to engage the damaged portion of the stud.

The stud isn't threaded all the way through. See 3:21 in this video. It's designed this way to ensure that an overly-long fastener can't extend into the receiver and interfere with the gun's function.

Pro Tip: If you're paranoid about cross threading anything (maybe not jar lids) you rotate it backward until the threads fall into place and then thread as normal.

Why not install the stud with blue locktite ...it'll be removeable next time around ...and won't back out with vibration...
@SynchronizorVideos
@SynchronizorVideos 3 года назад
I've never seen an 870 stock bolt back out due to vibration. Between the long length, fine thread, lockwasher, and compressibility of the stock material, they stay tight very well without any threadlocker.

whaddaya know, i did the same thing to mine while crossthreaded 😅it absolutely refused to thread properly and after 20-ish minutes i said "eff it. fine, halfway will work." and just forced it. now after 80 or so rounds it jiggle-wiggles and i like my face where it is, so....

Hay dude great video. I have the Remington 870 MCR breacher with the removal/changeable barrels and handle stock. I’m trying to change the stock to an aftermarket AR style stock but it seems the Remington MCR doesn’t even have a receiver bolt when taking off the existing handle grip. Can you please shed some light on this?

Just found your channel. Will be watching everything for the care and feeding of my 870, then everything else you have from there. Like the comments you have about cutting threads. As a lifelong mechanic it comes kind of naturally. but for the uninitiated, they are points worth noting. Thanks for taking your time for this.

I cannot even begin to turn the screw/bolt that holds the stock on with the biggest flathead I can find. The last person must have red loctited it or used an impact wrench. Taking a saw to the wooden stock popped into my head a couple times. It was my Dad's hunting shotgun and I just can't bear to see even the cheap/affordable stock destroyed...
@SynchronizorVideos
@SynchronizorVideos 6 лет назад
Hopefully someone didn't try using red Loctite. You may just be dealing with some corrosion making the stock bolt stick in the receiver stud. Try taking the gun's trigger plate assembly out, and spraying a little penetrating oil through the hole in the front of the receiver stud. If that doesn't work, there are some tools that let you put more torque through an 870 stock bolt than you'd want to with just a flathead screwdriver. That should be enough to thread the receiver stud out of the receiver, so you can save the stock. Then you'll just need a new stud & bolt, which aren't expensive. A gunsmith should be able to help you with that. If you haven't seen it yet, I have a detailed video on removing & re-installing 870 stocks and grips, which includes info on those special gunsmithing tools and tips for loosening a rusted stock bolt.

@BlackWolf42- 6 лет назад
Thank you, I've removed the trigger group and sprayed some PB Blaster up there. I'm going to give it some time and let it do it's thing. The next thing I'm going to do is to lay a high powered soldering iron on the insert and let it heat up - in the event some smart guy did use the red loctite. Sadly, even using the hugest screwdriver in existence, I managed to kind of mung up the head. The last bit of bite I can get on that screw will be after I let it heat soak... Then I pay a gunsmith to watch him remove it before I can even look around the store.

What to do if your main bolt just spins when you try to take off stock, what's the best way to get it to back out? This 870 is about 35 yrs old and when I attempted to remove stock the whole bolt and threads everything just spins.
@SynchronizorVideos
@SynchronizorVideos 3 года назад
It spins, but doesn't back out at all? Not sure why that would be. I would say try applying some rear-ward force on the stock while backing off on the bolt.

Hey I had a random question I just got myself an 870 and I'm having problems removing the wooden forend stock. I removed the nut which came out very easily I even tried a little tiny dab penetrating oil cause I know that's not good for Woodstock's but it's still won't come loose and I don't want to force it or break the Woodstock because it is still in decent condition what can I do to ease that sucker out of there?
@SynchronizorVideos
@SynchronizorVideos 10 лет назад
I'm kind of confused. Are you trying to remove your stock, or your fore-end? Either way, once you remove their respective fasteners, there should be nothing holding them on. Can you be more specific?
@frankiehernandez1854
@frankiehernandez1854 10 лет назад
I needed help removing the fore end without breaking it. I have heard on very old 870's sometimes breaking them off is necessary, but I wanted to save the wooden fore end because it is still in mostly good condition. Thank you for your time, I have already solved the problem with a few good taps with a mallet. I eventually wiggled it free and was able to clean both pieces so dis assembly would be easier in the future. Thank you also for your video about the differences in shell carriers I will be ordering one from factory for my 870 because it is my home defense weapon. If there are any reliability upgrades you can think of to add to my list I'm all ears.
@SynchronizorVideos
@SynchronizorVideos 10 лет назад
Frankie Hernandez While you're ordering the new shell carrier, check the breech bolt & slide assembly. If those are old-style too, you'll need new ones to get the full flex-tab fix. I'd also check to see if any of the original springs are feeling worn out, and make sure there's a stock bearing plate installed. Other than that, you should be good to go. 870s are all very reliable in stock condition, the flex-tab is the only significant design change they've gotten since they were introduced.

I question the use of anti-seize on the threads. Any kind of lubricant can cause over torquing when tightening ie, the threads will be under more pressure than designed for because the lube causes the threads to slip farther together than they normally would. The second thing is vibration from recoil might cause the bolt to unloosen, Most bolt science I have read states they should be kept dry and torqued to within certain parameters. If they are too loose or tight they can fail. Of course some applications require anti seize.
@SynchronizorVideos
@SynchronizorVideos 8 лет назад
Fair points. Thread compounds do change torque values, and there are applications where they should and should not be used. However, this is not a high-torque or high-load threaded connection that requires a very precise torque setting, so there's no real need to worry too much about how a thread compound affects that. Simply avoiding over-tightening is pretty easy. As for staying in place, 7/16-28 is a very fine thread pitch, so it's inherently stronger and more resistant to loosening than a coarser thread at the same torque would be. This gun has fired many, many rounds since this repair, and the stud hasn't moved at all. On the other hand, fine threads are much more easily damaged than coarse threads. The threaded hole in the receiver isn't hardened steel like a grade 8 nut, and 30 years from now, I don't want to have to reef on the stud and tear it out, messing up the threads in the process. Anti-seize helps protect against seizing from galling, friction, and corrosion, and I've seen threads - especially more sensitive fine threads or threads in softer materials - get pretty goobered-up from all of the above. Really, the anti-seize is probably not necessary for your average 870 owner, but I change stocks a lot more often than most folks will, and I'm sure I'll be replacing the receiver stud again in the future. I want this gun to last my entire life, so I take steps like this to help protect difficult-to-repair wear areas.

Do you know if the stud on an old Wingmaster has a slightly different thread pitch than the one on a newer Express? I have an older stock bolt from a Wingmaster that won’t thread into my 2 Expresses.
@SynchronizorVideos
@SynchronizorVideos 5 лет назад
It's possible. The first 870s had some odd part and design differences that Remington changed up soon after full production got going, so some very early guns can have minor compatibility issues with newer parts.

My earlier videos were shot using a little point-and-shoot digital camera that was auto-focus only. It didn't always cooperate in close-up shots.
@nomercyjeepin
@nomercyjeepin 11 лет назад
a little tip. next time start the tap through on the other side of the stud if the threads are still good on thatend. this way you are 100% sure the threads match. Other wise a great video.
