Remington 870 Detach Mag Unboxing

[Gatehouse]

I was looking for a 870 DM and of course Nechako Outdoors in beautiful Vanderhoof BC came to the rescue with the best price and service.

Here is the unboxing:

The box was green

It came with an astonishing amount of spacers already on the buttstock, plus extra spacers. Also included is a choke tube wrench (but no other choke tubes), some Allen keys of various sizes and the usual crappy style cable lock that comes with lots of guns and never gets used. Also in the pic is a roll pin punch that happened to be on my bench. And the pic is sideways, sorry.

The mags have these little prongs that stick off the top of them, and I was concerned they would bend easily but they actually seem fairly robust. The mags load and unload easier than any of the Turkish shotgun mags.

I propped the shotgun up on my man cave couch, it fits in well with the whiskey stains. It has a "breaching tube" on the end of it with little pointy ends. It's not nearly as terrifying as the pointy bits available on some of the Turkish semi shotguns, but it's frightening enough for most of us. I haven't been doing much door breaching the last few years, but if I ever get back into it, I know I am ready to go.

Just for fun, I swapped on a 26" 870 barrel to ensure it fits. It fits fine. So when my shorty mags arrive I will be good to go goose hunting. If I ever actually go goose hunting. I saw on another thread someone had put a 14" Dlask barrel on his, that's what this shotgun really needs to be uber tacticool. Although even with the 18" barrel it would make a great home defense gun for us in Canada where we can't store our guns loaded. And especially for more rural people like me who have predators creeping about at times. A mag full of slugs, one of 00 and one of some smaller shot will take care of bears, cougars, coyotes, wolves and pests pretty good. Just grab the appropriate mag for the task at hand, insert and blaze away. A flashlight mount is needed to really round it out.

I will hit the range tomorrow and launch a bunch of slugs, shot and buck through it, and let everyone know if I like it. I actually wanted the Mossberg more but I would rather have 10 6 round mags for the price of 3 Mossberg mags. And I don't think Mossberg has a dedicated 3 round mag for hunting so would have to pin the 5 rounders.

Nice, I like the 870dm to be honest. I’ve had a mag fed grizzly for awhile that works great after a thorough work over with a polishing wheel, so I can appreciate a mag fed pump 12g. The one thing I like about the 870dm is the ability to close the bolt on an empty mag, if I remember correctly you can do that. I handled one the last time I was down at Reliable, you can’t do that with the grizzly mag fed and port loading a single isn’t possible as the follower blocks the bolt from closing on an empty mag.

I think Rem has a better mag setup than the grizzly, which is their big weak point. Once you tweak them in a couple areas they work nicely, hope your 870dm is good to go out of the box. I shot a few grouse with my 14” grizzly and it was fun as hell to finally have a practical use for it since I have a choked barrel for it.

That's a pretty sweet rig. I have the same furniture, sights and door breacher on my 870 non-DM and the handling is excellent. Now you have me thinking about adding a mag model, LOL!

Curious, I can't see the cross bolt safety, would S&J oversized one fit? I have one on my 870 and it is way nicer and tactile than the OEM version.

 

[Gatehouse]

Took the new girl to the range today, tried out a bunch of ammo and it all worked fine. Gotta ditch some of those spacers, I'm a pretty big guy and the LOP was too long for me. Some fellow who was about 5'9" tried it too, and it looked like he was barely holding onto the long stock. Magpul stock feels nice though, good grip

One down side to the mags loading and unloading so easily is that you don't want to drop them. I dropped one and it was like a yard sale, 3 rounds popped right out. Mags are a little snug but I'm sure things will smooth up a bit with some use.

I don't see why not, but I'm sure Simon can answer your question for sure!

Getting 4 spacers along with the Magpul stock is standard.
The beauty about the system is all you need is a coin or choke wrench to remove the bolt and you can remove or add spacers on the spot.

Thanks
Yes ours fits no problem

 

[Butcherbill]

Have you tried any 3” shells, curious to see if it feeds them them reliably. My mag fed grizzly doesn’t like 3” shells unfortunately, I’ve been able to get it up to around 75% of the time it will feed them but that’s the best I think I can get it to do.

 

[Gatehouse]

I don't think I have any 3" shells. After doing lots of testing with 3" slugs and buckshot I determined that the added recoil did not increase the performance significantly enough to warrant the added recoil. I'm not a waterfowler but I feel that they do offer gains when hunting waterfowl. If I find some 3" kicking around I will try them. There is for sure enough room in the mags to hold 3" though.

Excellent. IMO, it is a mandatory upgrade.

 

[Gatehouse]

Took out one spacer and I like it better. Slick system. The more I shoot this thing the more I like it. I wish they came out with a 20 g model, I would buy 2 and 20 mags!

 

[Ironheart]

I love these "unboxing" threads!

I do want to get one if these for myself, the hardwood version.

Anyone have any issues of any kind?

Will it eat up that el cheapo Wal-Mart white box Winchester birdshot?

 

[Butcherbill]

I quite like the look of them, I find it funny that the Rem mag fed is a clone of the Grizzly mag fed if you think of it. Oh the irony, for so long it was the other way around lol.

 

[Gatehouse]

I liked this shotgun enough to buy another one. here is the box:

I also got some more mags, including some 3 round mags for hunting. I apologize to all those who are really into "unboxing" videos as I didn't even snap a pic of the mag boxes, but they were also green.

The 3 round magazine to comply with 2+1 regulations is pretty ingenious. While you can insert the 6 round magazines with a closed bolt (giving you 6+1 capacity), the 3 round mags you can't. You must load with an open bolt. So insert mag, close bolt and you have a loaded chamber and 2 extra rounds in the magazine.

Attempting to load with 3 rounds in magazine on a closed bolt results in this:

This one also came with a terrifying "breaching choke" but I will swap it out for some other Rem-choke constriction. The breacher choked shotgun can be a range toy and the other one will be used at the trap range and for hunting, so I don't want something that will poke out an eye. Anyone want to trade a Remchoke, let me know

Now they just gotta make these cool 870 DM models in 20 gauge and I will be happy!

 

[Butcherbill]

Interesting with the 3 rd mag on the closed bolt, I was wondering how that was going to work. It seems more and more like Rem really thought out how they designed their magazine on this model.

 

[Gatehouse]

Yes, it's a good solution for the 2+1 hunting regs. I have a Derya semi and the hunting mag with that is a 2 rounder, so you can put a loose shell in the chamber then close it then add the mag, but it's a bit of a pain, if you are shooting grouse as targets of opportunity while driving between camp and hunting spots,so basically you hunt with a 2 round mag. The 3 round mag will be extra fun.

I can see that, it’s the same with my mag fed grizzly. I made plugs for the mags at 2 shells, if I’m in the truck and see grouse it’s only 2 I get to play with. If I’m walking old trails I have the luxury of loading the one in the chamber, I can load 3 quicker in a tube fed gun than 1 plus the mag in my grizzly. It’s still fun to shoot grouse with though.

 

[TFunfer]

Looks great. How much are spare mags selling for?

 

[Gatehouse]

Got about 750 rounds of slugs through one of mine now. No problems, operates fine. Everyone loves shooting it.

Only thing I'm not happy with is that the magazines are still tight to insert and remove. Figured they would have polished themselves a bit smoother by now.
