Magazine Extensions for Remington 870 Shotgun (Nordic Components, Choate, TacStar, Remington, ATI)

UPDATED REVIEW: 7 Magazine Extensions for Remington 870 Shotgun (Nordic Components, Choate, TacStar, Remington, ATI, Vang Comp Systems, Wilson Combat)

This is new version of the review of Magazine Extensions for Remignton 870 shotgun. This time I added new information about the extensions I reviewed earlier and review about the new one.

Magazine extension tube is one of the first upgrades shotgun owners usually buy and install. This is understandable because shotguns have very limited number of rounds. There are a lot of different magazine extensions available on the market. You can get magazine extension separately or complete magazine tube extension kit

You will see advantages and disadvantages of each of the magazine extensions. But first, here is rating of the magazine extensions (based on my humble opinion).

Rating of the magazine extensions:

1. Nordic Components magazine tube

2. Remington magazine extension tube

3. TacStar magazine tube

4. Choate magazine tube

Nordic Components Magazine Extension for the Remington 870

I have put Nordic Components extension on the first place for a number of reasons. And this is the best magazine extension I have ever seen.

Extension (consists of 3 parts)

Nordic Components Extension

Nordic Components Extension

First of all it is made of aluminium. Second advantage is that it consists of 3 parts (tube, tube cap, tube nut). This extension comes with high-quality spring with black coating. And the best thing – a lot of shooters use these extensions and have no problems with them.

Now let’s have a closer look at all advantages Nordic Components extension gives to a shooter…

This extension is lightweight. If you compare it to other ones you will see a great difference in weight. Remington 870 is a heavy shotgun and is nice to have such lightweight extension.

It consists of 3 parts: tube, tube end cap, tube nut. This allows you to have one +5 tube for competitions and one +3 tube for home-defense. +5 tube allows to have more rounds but it sticks out too much, it is much better to have a shorter tube for use in close quarters.

Also, after installation, you can take out the end cap and look inside your magazine tube to check if everything is ok.

The spring is fantastic. This is the best spring for a magazine extension you can find. I have seen many of them, the best one is from Nordic Components, the worst one is made by Choate.

I have also teste the follower from Nordic Components and it works great.

The price of this magazine extension tube is about $80.

Remington Magazine Extension for the Remington 870

Original Remington extension is on the 2nd place. It is good extension but it has a lot of differences. Bundle:
Extension Tube
Clamp (without swivel)
Mounting screw for clamp

Remington Magazine Extension

1. Remington magazine extension is a little longer than the other ones. There are many theories about the purpose of this nose cap in the end of the tube, but the truth is that it allows attaching a bayonet (for example, M7 bayonet).

If you want to add a bayonet to your shotgun you will need an additional bayonet adapter. For example, the one from S&J Hardware, the price is about $80-100. Original military U.S.M.C. M870 MK1 Bayonet Adapter/Magazine Bracket (which is no longer manufactured) is difficult to find and will cost you about $250.

2.  This extension has a groove around it that provides an interlock for the mounting screw of the barrel clamp. It positions the clamp on the extension and locks it in position. This is one of the advantages of the Remington extension because clamp can’t move under recoil. Some of the shooters say that other barrel clamps are not as reliable as the one by Remington.

ATTENTION: This groove may cause a follower from the Vang Comp Systems to stick inside the magazine tube.

3. Extension consists of two parts. This allows smooth feeding. Some other extensions (TacStar and Choate) are made from solid tube and have small “step” inside tube which can cause jamming of the spring or follower to malfunction. This extension is the most expensive one; the price is about $100-120

TacStar Magazine Extension

TacStar Magazine Extension

This is one of the most popular magazine extensions for Remington 870 shotgun. You can select polished blued or matte parkerized variant. The tube is made of solid piece of metal. Some of the users of this magazine extension say that parkerized coating was not very durable. Other that that it works perfectly and does not need any modifications.

The of this extension is about $50-60

Choate Magazine Extension for the Remington 870 Shotgun

Choate extension is on the 4th place due to numerous problems with feeding and installation. Bundle:
Clamp (with swivel)
Mounting screw for clamp
Orange follower with tail

Choate Magazine Extension

Choate Magazine Extension

This is one-piece extension made of metal. It is available in polished blue or matte blue finish. There are several known problems with Choate magazine extension:

1. Spring needs to be cut to proper length.

2. Follower is too big and diameter need to be reduced to slide freely in the magazine tube.

3. It is difficult to thread it fully on to the existing magazine extension tube. Fits very very tight.

4. Problems with feeding, follower sticks.  Can be fixed by polishing the inside of an extension tube. It looks like this extension was stamped and not made of solid piece of metal.

The price is about $40-50

    I haven’t really run it through it’s paces but I like my Sage International magazine extension. I won’t repeat myself here, if you want to see my thoughts you can see my blog post about the additions I made to my shotgun here:


    P.S. I am probably going to try a Nordic Components one soon (probably a +2 to go with my 18.5″ barrel) with the high praises Vitaly gives it.

  2. Oodin January 28, 2011


  3. admin January 29, 2011

    Thanks for your comment, Jon!

    I really want to try Sage International magazine extension in future. It looks good.


  4. simon February 1, 2011

    If your looking to really show what are good magazine tubes on the market you should really look at doign a review on Vang comp and S&J hardware.
    Those companys are the only ones that make a solid steel mag tubes not thin wall tubing.
    Fot shotguns that are used for law enforcment, where the magazine tube may be hit off somthing hard, the solid steel tube is the only way to go.
    Thin wall tubing has the issue that even a small dent and the magazine will not feed.

  5. Oodin February 1, 2011

    Simon if your magazine extension is made from thicker steel than the Sage it must be heavy! How much does your +3 weigh?


  6. simon February 1, 2011

    I will weight if for you and post here
    Not as heavy as you would think

  7. Oodin February 1, 2011

    That would be great Simon, thanks!


  8. admin February 3, 2011


    Thanks for your comments! I didn’t know about S&J hardware magazine extension. It is nice to see that it has a Bayonet mounting end cap and sling mount.

    Also, I like your new green follower.

    I plan to review following extensions in future: S&J Hardware, Vang Comp Systems, Wilson Combat (Scattergun Technologies) and Sage International.

    I like solid steel tubes but they are heavier than aluminium ones.


  9. Mark February 7, 2011

    If your shotgun will see any real use in a tense situation (even for home defense) the mag extension really needs to be clamped to the barrel. One smack of that extension tube on a door jamb, floor or anything hard, and it could fly off, along with all your rounds and the spring. This is why Remington uses a clamp. The thread engagement on these tubes is not enough to hold them on if hit hard. That is why I use the Remington tube with clamp. Steel is also more durable as it is less likely to be dented and less likely to break off. Aluminum, while lighter is not as strong. If really you want lightweight, do not install an extension in the first place. The added weight of the extension and the additional rounds is significant and not to be underestimated. My 870 fully loaded takes a toll on my arms when I have to clear my house room by room.

    • admin February 7, 2011

      Mark, thanks for your comment!

      First of all, I absolutely agree with you that magazine clamp is must. I use the MOD-C clamp made by CDM Gear. This is the best clamp I have ever used and also it allows you to have a light on your shotgun.

      But I don’t think that aluminium tube will break easily especially if it has a clamp.

    Reference – Choate Mag Extensions Comments
    3. It is difficult to thread it fully on to the existing magazine tube. Fits very very tight.

    One reason might be due to the fact that older 870s have a magazine that has a 1” X 12 TPI (threads per inch) end. Newer models – with the dimples and ratchet system – are threaded with a 1” X 10 TPI. Confirmed by Remington technical staff. The Choate mag extension will not work with older 870s. They do not offer ones that do. They also do not warn you of this fact. My 870 is of a 1981 vintage with the 1” X 12 TPI. Choate P/N 01-04-05 will not fit as it has the 1″ X 10 TPI. It makes one revolution and hangs – leaving a 1/8” gap and a loose barrel.

    • admin March 10, 2011


      Thank you very much for your comment and for sharing this important information.


  11. Charles March 10, 2011

    Reference my earlier comment regarding the thread mismatch on older 870s and Choate extensions:
    Reference – Choate Mag Extensions Comments
    3. It is difficult to thread it fully on to the existing magazine tube. Fits very very tight.

    The fix is to bore out (remove) the first thread on the extension. This gives it room to fully seat before the mismatch of the two threads take hold. It now fully seats on the 870s magazine – with no play whatsoever. A lathe is best but a Dremel will probably work also.

  12. simon March 12, 2011

    Some very good info hear guys and all course i do belive you on the 1/10 v 1/12 change.
    But i have rebuilt 100,s or 870 shotguns over the last few years, 50 this year alone.
    All with eaither our +1 ,+2 or +3 mag tube.
    Haveing built for customers on older wingmasters, new express and some 870 police. None of them had any issues with threading on the mag tube.

    • Sam April 21, 2016

      I was wondering what brand magazine extensions fit the old Wingmaster 870 1-12tpi threads. I have tried the Choate and it definitely would not thread on. I tried the same extension on a newer Express 870 and it worked fine.



  13. JVO April 28, 2011

    Im wondering something about the Nordic extension for my 870. I know Nordic are the gods of extensions, but what im wondering is this…

    If I replace the factory +2 extension on my 18.5″ 870 Home Defense with the Nordic follower, +2 tube, tube nut, and extension cap, will it give me an extra round in the magazine? From the factory it only holds 6 in the magazine tube and 1 in the chamber, if I can make it 7+1 for $70, im certainly going to do it. Anyone know?

    The guys at Nordic don’t seem to have the answer I seek and I don’t want to buy the stuff to find out I wasted my money and it doesn’t give me an extra round. Because honestly the look and functionality of the factory tube is fine to me, but I REALLY want that extra round lol. Thanks guys!

  14. Oodin May 1, 2011

    Changing the factory +2 out for a Nordic +2 will not give you an extra round. Gun Connection is on the Shotgunworld Forum as MAX100 offers a magazine extension that is flush with an 18.5″ barrel and gives an extra three rounds compared to the standard +2 for this barrel length, you could contact them and see what they know.


  15. JVO May 1, 2011

    Thanks for the reply Jon. But actually it will, and it did! See the Remington factory extension has a ring around it that the clamp screw goes through to hold it in place (shown in the second picture), that ring is actually a stop. It prevents the follower from going past it therefor sacrificing a round in the magazine. The Nordic (and many other extensions) don’t have that milled/pressed in ring in the tube so the follower is able to go all the way to the end of the extension and fully compress the spring instead of 2 1/2″ short of it. Its about 1/8″ short of the barrel, so its not completely flush but that’s fine by me. I got the Nordic today, installed it, and I can now hold 7 rounds in the magazine instead of 6!!!

    I don’t know if this helped, but I will also note that I cut the Nordic spring down to 20″. The factory 29″ spring in an 18.5″ barrel is completely unnecessary and too hard to feed rounds into when past 4 rounds. Now this whole process could have been done a bit cheaper, I didn’t need the Nordic as the TacStar would have worked fine to achieve the extra round in the magazine, especially since I paid a total of $87 for 1 round (after the follower) lol, but I wanted the best! Overall, I am very happy!!!

    p.s. How long is the barrel on the 870 used above? Thanks!

  16. Oodin May 1, 2011

    Well, I stand corrected then :)

    I believe those are all 20″ barrels fitted with what are called +3 extensions by the manufacturers :D

    I was planning on trying out a NC +2 magazine extension soon, might need to bump it up the list…


  17. JVO May 1, 2011

    OK yeah I thought it was a 20″ after I read you the part saying they were +3 but wasn’t sure. Hey also look into the Scattergun extensions. I know that one is $5 cheaper than the Tac-Star, a bit different in design, and parkerized. Plus its used by the Secret Service, Border Patrol, and FBI so its probably good stuff. I almost regret for half the money not going that route lol. Thanks for such a helpful article!


  18. Oodin May 1, 2011

    This article is actually Vitaly’s, he owns this blog. I just post here. Though I did write one article for him:


  19. artem May 11, 2011

    I would like buy one could you please help me!?

  20. herb July 26, 2011

    I want to attach a Bayonet to my NEF Pardner 12 GA Pump Shotgun. It is an exact COPY of a REMINGTON 870. My Pardner has a 18.5 “barrel.I donot have a mag extention on it now. Do I NEED one to attach a bayonet to the Shotgun? All replies are appreciated. I’m also on FACEBOOK: Herb Walker

    • admin August 4, 2011

      Herb, I think yes, you need a magazine extension because bayonet is attached to a shotgun using the end of extension and bayonet adaptor (for example, the one from S&J Hardware).


  21. Ed June 9, 2012

    I have used Choate products for years with success, and have had no issues with their magazine tube extension. Maybe you got a bad apple as your evaluation sample. Try getting another tube and reevaluating, OK? Thanks.

  22. Don July 21, 2012

    I just wanted to say that I just bought a Benelli SuperNova,yeah its not a Rem 870 but I have found a great may extension from Briley manufacturing out of Texas. It high quality machined annodized aluminum.Its made to be equipped with their picatinny rail that slides on and stops on the end that flushes up to the tube. The end has cross hatching for gripping and tightening the piece down tight. It sits 1/16 behind the barrel and allows me to have 7- 2 3/4″ or 6- 3″ shells. I was really impressed with it when it arrived. I made the mistake of ordering a Carlson from Cabellas and it was dissapointing junk so I sent it back. If you want to check these out go to

    • Vitaly Pedchenko July 23, 2012

      Don, thanks for your comment! I have bought Benelli SuperNova too (post about it is coming soon) and Nordic Components extension but I’ve heard only positive feedback about Briley extensions, good choice.

    • fled May 12, 2013

      Carlson’s get their extensions from Choate. Same tube, spring, follower just doesn’t say choate on the plastic end cap. They charge more than choate too. I got one super cheap on closeout and plan to use Rem factory spring, S&B follower and TIG weld a steel washer in place of the plastic cap on a future 1100 tac build. I have used Scattergun (Great with Hi-Viz follower and spring) Rem factory (Great but heavy and expensive if you can’t find a cheap take off) and Sage (Inexpensive but required fitting cause thread base on tube was too long and spring was way too stiff and long went with 870P factory spring and all OK)

  23. Synchronizor May 22, 2013

    It’s worth mentioning here that the Remington extensions share the coupling nut, clamp, and other components the same way the NC extensions do. If you have one Remington extension – the +2, let’s say – all you need to buy also have the option of the +3 extension is the +3 tube, which can be ordered straight from Remington for $26 (plus shipping).

    • Vitaly Pedchenko May 23, 2013

      Yes, you are absolutely right! I think that original Remington extension is a very good choice.

  24. Rick May 22, 2013

    Is this still your current listing as of 2013


    • Vitaly Pedchenko May 27, 2013

      I plan to update this review soon. There are extensions which are not covered by this review but all of the info about the extensions in this review is correct.

  25. ogden lane December 1, 2013

    One thing I have read bears mentioning here; some extensions do not have the bracket connecting the extension and barrel. Reviewers noted that this leaves a gap that can catch fabric, wires, etc., constituting a problem, especially when dexterity is at a premium.

  26. g. roddy December 11, 2013

    I tried the 1 round extension made by Wilson. It didn’t add any 3″ rounds to my Express Magpul Tactical and I don’t shoot anything less than 3″, It also didn’t match the finish it was more grey the express finish is a powder black also I didn’t care for the follower so I used the one that came with the gun.I didn’t really like the fixed sling mount or the hole in the end of the tube. It was made solid but just wouldn’t work for me so I sent it back. Now since I removed the stupid dimples some Remington engineer(probably a democrat) installed the original spring is to short so I had to add a spacer till I get this mess finished.
    Sure wish some one would make a dimple remover I measured the inside diameter of the tube at .912. I guess I could have a machinist make one with his lathe,

  27. Sara Pialla June 19, 2014

    A magazine extension was the first thing I bought soon after getting a Remington 870. It was from Nordic Components, made from aluminum and I never had any sort of issues with it. I have it for more than 2 years now and it works like when it was brand new so I am very happy with Nordic.

  28. Orlando June 21, 2014

    I was wondering what you thoughts were on the TacStar Magazine Extension. Glad I came to this post and read your reviews.

  29. Synchronizor September 23, 2014

    A note on the price of the Remington extensions; they’re factory-priced at $90 – $120, but you can usually find them for a lot less ($50 – $70 range) if you shop around. At the moment, Midway USA has blued +2 & +3 kits in stock for $46.99.
