Disassembling a Remi 870 express?

Help a shotgun noob out. I have a new Remington Express 870 syn 12ga with 2 shot extension that I can't figure out how to disasemble. I think I'm suppose to remove the nut at the top of the pump/slide. I've tried to remove it by hand and brefily with plyers but it's not moving.


Any help would be great.

Thanks.

If you're referring to the magazine extension tube, try loosening up the coupler thingy first that couples the barrel to the mag tube (the thing with the sling swivel on it). Should be a slot-end screw.

Yup, need to remove the coupler, then remove the nut at the bottom of the extension. When I bought mine (used) the nut was so tight I actually got the extension off before the nut! Once you get the extension nut you can follow the instructions in the manual. If you bought it used and need a manual, go here.

Yeah, I wish I had known that before I tried disassembling mine. Bought the sucker brand new and got it home and started taking it apart, couldn't get the damn mag extension tube off for the life of me. I wrapped a leather belt around the nut and had a pair of vise grips on it and was cranking on it and it wouldn't budge, and I ended up with a bunch of idiot marks on the nut because the vise grips kept slipping. Then it dawned on me to try loosening up the coupler first. :rolleyes:

Yeah, I had to use one of those rubber strap wrenches to get my extension nut off. Sucker was tight!

A cheap rubber wrench is a godsend when disassembling new firearms. Saved a lot of scrapes and scratches. Such a simple idea.

That was it! Thank you.

I got some idot marks on my mag tube coupling ring but I covered them up with a good old black sharpie!

Now that you have figured out the mag tube here is a video of the rest of the tear down. His demo model was a 5 shot so it had no tube, but the rest is the same.

Tercel,

Thanks I can't wait to shoot it. No better way to get to know your guns than to take them apart. I also love the fact that it's a 7 shot!

My 870 is easily one of my favorite guns. It really is a lot of fun to shoot and it's cheap to shoot if you get those birdshot/target value packs from Walmart. Me and my friends get a bunch of shells and some clay pigeons and I have a pigeon pitcher and that is lots of fun. It's also fairly low maintenance, easy to take apart and clean, and I've shot hundreds of shells through it in an afternoon and the gun was still pretty clean at the end of the day. Here is mine:

Seem lately that shooting my shotgun is way more cheaper than shooting my handguns . And its still fun ! I take my shotguns out and shoot cheap birdshot though them . Fun and still cheap and keeps you familiar with the gun . Thats what my boy and me do here lately for fun .

You guys are shooting clays with a 18 inch barrels? Ok now I am getting one. I never liked the long barrels at all, anything over 24 inches is too much for me.

Me and my boy have a 20 inch and a 18.5 inch barrels and we like shooting crap like cans and such . Our guns are mainly more defensive guns rather than sport guns.
