    Well after being excited about my new magpul MOE for-end coming in the mail, I went to install it and the CASTLE NUT of the old fore end will not budge one single millimeter. I took a hairdryer to it and still does not work. The model i have is the REMINGTON 870 EXPRESS MAGNUM. I noticed that there are dimples in the tub (pictured below). You can see that rectangular slit, there are 3 of them. My guess is that something dips into those, possibly the castle nut. The magpul foreend says it fits standard 12 GA 870 shotguns. No details on the magnum or any other model. Please help! Thanks!

    Upon further inspection, the nut stops before the dimples inside the tube. So WTH is causing this thing to be this way? Thanks

    No clue; there are some vids on youtube found for "870 express magnum castle nut removal".

    Not a problem on the Mossberg 500. ;)

    Just called remington and they were no help. The call lasted less than 1 minutes. Guy basically said there is nothing they can do. It looks like this is not a common problem. I am out of ideas. I have spent the last 3 hours trying to pry at this thing. Last think I can think of it to break the foreend and get the tube out. But then again it is still stuck.

    Get a nice strong piece of pipe, steel, PVC, whatever, put it on the end of your wrench and use it as a bolt breaker. Works for me on my truck, maybe it will work for you to get some extra strength behind it

    Thanks for the tip. I will try it. Hopefully it does not break anything else though. The threads are a bit delicate.

    Wanting to replace OEM parts, they are stuck, poor customer service, worried about breaking other things like its delicate threads...

    Must have been a Moossberg issue too at some time or other:

    http://www.combathunting.com/WINCHESTER-Shotgun_Forend_Wrench_Removes_Castle_Nut.html

    Shotgun Forend Wrench works with Remington 870 Shotguns, Mossberg 500A Shotgun, Mossberg 500c Shotgun, Mossberg 835, FNH USA SLP shotgun, Browning BPS Shotgun, Ithaca 37 Shotgun made since 1981, Winchester 1200/1300 Shotgun and other popular Shotgun models. This is a great tool for any gunsmith or shotgun owner. Made from high quality steel with nickle plating. Removes castle nut.

    Mulanlabelxxx, do you have the tool provided by magpul, or the original remington one?

    Is the nut not spinning when torqued upon? have you sprayed it with some WD-40 and let it sit for a while? Are you the original owner or did you buy it used? If you bought it used, the previous owner could have used lock-tite on the threads. Which they don't need.

    If you don't have the tool, you can make one by cutting a section of 1/8" steel strip that will fit between the two notches on the nut.
    Grip the steel strip with a pair of Vise-Grips and unscrew the nut.
    WARNING: Some people will recommend using a pair of needle-nose pliers as a spanner to unscrew the nut.
    One slip and you'll damage the thin steel tube of the action bar assembly and will have to buy a new assembly.

    Some people even use the claw end of a hammer to unscrew the nut.

    Or..........

    Each 870 has forend wrench built in.

    [​IMG]

    Remove the forend tube assembly and as it comes out of the receiver the breech bolt will of course fall off the slide. That slide fits perfectly into the notch in the forend tube nut. If the forend tube nut is on there to tight use some channel locks or pliers on the slide for leverage untill the nut is broke loose then you can simply twist it with your hand to remove the nut.

    And if you already have the spanner tool, or that nut isnt what you are referring to, then ignore this nut and my previous 5 posts! :D

    MLXX, You might want to invest in one of these.

    http://www.amazon.com/Advanced-Technologies-Remington-Mag-Socket-A-5-10-2325/dp/B004R71KYC/ref=sr_1_3?ie=UTF8&qid=1369377473&sr=8-3&keywords=remington+870+forend+wrench

    Also, try a few drops of penetrating oil on the threads and the nut. If it is an older shoygun, the nut could be a little tight on the threads, and some penetrating oil could help loosen it up. As far as help from Remington, you are modifying their product. Most companies will be of no help if you are doing so. it's kind of like doing a disc brake rear end upgrade to a 1998 Ford F-150. The local dealer will tell you to go pound salt if you ask them for help with a problem in the process, even though you are making the truck safer by shortening stopping distances. Basically a no win situation.

    P.S. Don't mind Hocka. He just forgets that for every "OMG, my Remington's broken post, there are a few hundred thousand that are serving their owners well when they are called upon to do so. Everybody posts that they are having a problem with their brand A, model C, but nobody ever seem to post that their Brand Y, model Z is the effin' bomb. Mossberg makes a great product, it's just not the best fit for all people. many like myself have both in their collections, and they enjoy each equally. I would carry my Mossberg or my Remington to hell and back, and know that I have a shotgun that will work for me no matter what. and in my case, said Mossberg is well over 60 years old, has fed 3 generations of my family, and is still going strong. The Remingtons are about a decade old, and have kept food on the table since day one. I trust both with my safety and my life, because I know I can, as will my daughter long after I am gone.
