    Hello everyone. I just got a new Rem 870 Express, 18" bbl with the factory 2-shot extension (model 25077). I am having a difficult time with field stripping it. The manual does not cover the models with extension tubes. I called Remington, and the nice gentleman said that the very end of the extension tube is what I need to unscrew. It is on extremely tight and won't budge. The nut (if you want to call it that) at the base of the extension tube, just forward of the fore-end, will loosen but only with tons of torque. I have already scratched this nut trying to get the darn thing off. Can anyone shed some light on this before I go crazy? I have other 870's and it shouldn't be this hard to take it down for cleaning. Thanks in advance for your assistance.

    Loosen and remove the barrel band. Then get a pair of round jaw pump pliers, and using some leather or rubber for padding around the tube nut, loosen that.It has a detent that keeps it tight so you must get past that and sometimes they are a bit stiff. but once the nut at the barrel ring, that is, the permanent piece that keeps the barrel located at the mag tube, gets loose, it should slide right off

    Or what you are more likely to have on hand---channel locks and a t-shirt------take your time and don't squeeze too tight-------remove the barrel band first.

    I just got the Marine Magnum version or the same weapon. Had to use a pair of 12inch water pump pliers with leather padding to break the magazine extension free. Of course, unscrew the clamp first. And by the way, be prepared - the magazine spring is longer than you think! I ended up using a barrel cleaning rod to get it back in without kinking or binding. Enjoy and good luck.

    For unknown reasons, Remington has been shipping extensions screwed on so tight you need pliers or a strap wrench to break the coupling loose.

    If you scratch it up, call Remington and complain, they'll send you a new coupling.

    So far, no one has been able to get an explanation from Remington why the couplings are over tightened.

    When replacing the coupling, screw it on just snug, then give it ONE more "click".
    You should be able to unscrew the coupling with just your fingers.
    Over tightening the coupling is not only unnecessary, it can cause problems for the gun.

    And by all means, be careful. That extension is under a lot of spring pressure. If it squirts out of your hands, it can do some damage. heck, it ought to be the last resort option of the gun. Mag extension trigger!!!!

    Once you get it off and put it back together, you only need to put that nut back on finger tight! There is absolutely no reason to put it on so tight that you need a tool of any kind to take it off. No screwdrver, no pliers, no nothing.

    I've been in the field with my 870 and during a reload didn't push the shell forward enough. It was past the loading ramp, but not enough for the catch to grab the rim of the hull. This locked up the receiver. I couldn't pump it forward or backward. Since I put the nut on with a big screwdriver, I couldn't budge it by hand. I went back to the truck and didn't have a screwdriver or pliers. I had to go home to take the nut off.

    If I would have only had it finger tight (like I have since) I could have taken care of the problem in about 30 seconds.

    The ball detents in the nut will hold it in place. It isn't torqued on like most nuts. I have never experienced any problems whatsoever with the gun or recoil loosening the nut.

    Remember tha the extension is 2 piece.

    When you reassemble the gun, you put the barrel on and then the nut, then install the follower, spring and tube.

    dfariswheel,

    Is this really true that Remington will send me a new one to replace the one I scratched? Will I have to poor on the drama or just be honest? Also, my gun is a about a year old and has the side folder "protector" stock.

    I did use a T-shirt and pliers but still left marks when removing mine.

    Probably put on dry and mechanically tightened.

    Ever have the new kid do an oil change and put on your oil filter with the filter wrench then try to change it yourself the next time?

    Or the tire guy put on your new tire and tighten the lug nuts with an air wrench and then try to get it off to put on the spare after it went flat in the middle of summer when its a 110 out? :cuss:

    Several people have called Remington about scarred couplings due to the factory installing them too tight.

    Remington has sent them a new coupling without any histrionics.

    Give them a call.
    Explain just what happened, and ask for a new coupling.
    It's not your fault when the part is damaged due to improper installation by the factory.
