If you don't have a dremel, just a regular power drill will work. Drill out as much as you can, and then turn the bit on an angle like this ---> / and work it up and down. It "cuts" the rest of the dimple off.

You must use a socket that barely fits in the tube and remember to use lubricants. If it's a too small the tube might bulge. A little common sense people!

I had to use the dremel drill method. I wanted to go the socket route, but none of mine fit in the tube correctly. Anyway, it works now and I'm very happy.

Took me all of 15 minutes to do the socket method, as described on page 1.
Start with a slightly undersized socket, lots of CLP, and tap it in there. To get it out, put a long bolt into the mag tube from the breech end and when it sticks through, put a nut and washer on it to lock the bolt in place. Use the bolt to pull it out. Repeat with a larger socket, I think I ended up with an 11/16, which had the perfect outer diameter. Flatten it all out with a punch or small hammer while the socket is still in there, pull it out, and voila, you're done. |

I done the socket method on a dent in a mossberg tube. But I removed the tube first and put a long extension on the socket. Hammered it all the way down the length of the tube, twice. Removed the bent pefectly.

 Just finished the socket method. used an 11/16 socket. (note: I have several socket sets... The craftman was extremly tight and almost didn't even fit period, thus opted for one that was a had enough of a gap that slid in but with little to no wiggle room) hammerd in then had to vice wrench to get it out......for a moment i thought "crap I ruined the gun" but it did eventually come out. Finished it off with a dremmel by minimal grinding and polishing on the inside until smooth . Note!!! Its a bit risky because I noticed the tube a bit bulged , not much but enough where the barrel now is tight over that point. Goes on ok but needs a little convincing to come off. I will follow up with pics when I install the mag extension. thinking of ordering a 2+ from wilson. Toping it off with a 18 in rem barrel from cheaper than dirt. So far im looking at about $165. to convert rem 870 express to a HD shotgun. |

i did the socket deal on mine back a few years ago. worked great.
if you are affraid of not getting it out... deffinitly take a bolt and put it through the socket (threaded side up) and put a nut on it so you wont lose it down the tube. if the socket gets stuck youll have a handle to help pull it out... |

So does anybody know why my 870 HD that came from the factory with the extention tube has dimples on the mag tube? I'm not going to do anything with them yet as it loads 6 shells in the tube and fires all 6 without a problem. I was just wondering why they may have done this.
Thanks in advance. Bill |

I have an 870 Express with the dimples. I wonder, why are the dimples there in the first place? I ran across a thread in another forum, and here is what someone has to say:
"IF you decide you want to remove the magazine tube extension and return the standard length magazine tube. you are going to need a new (steel) magazine spring retainer, magazine cap nut, detent ball and spring, since the plastic magazine spring retainer also acted as the cap nut detent. Now for the rest of the story...IF you have one of these 870's with the dimples and you remove them, you will need a detent spring and ball, plus the tools to set the spring and ball into the barrel lug. The reason being is that they will NOT be present and need to be there, why you might ask...well because the detent is what is going to keep your magazine tube extension from unscrewing from the magazine tube. Unless you buy the bracket that clamps it to the barrel, which is another story." Link to other forum Can someone reword this for me so I can understand what I am giving up by not having the dimples if I remove them, but do not add an extension to my mag tube? I wanted to go ahead and modify the magazine tube so it's ready to accept the extension once I get one. However, it seems from this thread that in doing so, I will have other problems. What is in the extension kit that allows me to go without the dimples? What keeps the magazine tube from unscrewing on an extended tube? Also, what sort of problems will I experience with no dimples on a 4 shot mag tube that originally had dimples? |

I got a dremel with a sanding disk and took bout 20 minutes last night when I got off work. I have an el cheapo dremel from wal-mart which is only bout $25-30, and came with the sanding disk. I had a strong flash light and sanded down the dimples going slow and not mar up the tube but focused on the dimples,
Sand and check every so often. I also had some very fine sand paper bout 600 grit or so ( really can't remember, just guessing), and finanlly had smoothed dowm the dimples. I am using scatter gun technologies 1 round extention, and used the mag follower to check smoothness in tube. Just make sure no burs are left in the tube and you should be fine, as well do a function check for feeing of shells and your good to go. |

I did mine a few months ago. I started with the socket method...I was conservative at first, and worked my way up in sockst size. At one point, there is nothing more the socket can do...so I bought a 6 piece Stanley pin set from Walmart for $9, and started to bang on the outside of the dimples against the socket inside to flatten them out further. The final touch was some dremmel grinding internally to make is oh so smooth.
I thought about blueing it, or using some other for of finish to prevent corrosion, but a gunsmith at a local store told me not to bother with doing anything. So now, all I need to do is buy a 2 round extension, and I am ready to go. |

Go to www.aiptactical.com and put your cursor on "customer service" follow the drop box down to "how to Videos" and watch the video on the Tube Extension Kit" follow that video and all will be fine. DO NOT use the method of putting a socket in the tube and pounding on it. This can FUBAR the mag tube and you will have to send it back to the factory as that thing was factory braised by robotic welders and in a jig lined up perfectly. If you crack that braising by pounding on it then it will never be right again and you will have function issues unless factory repaired. Yes, there are gun smiths out there that could fix it but I would never try it. I have sold two new receivers in the past two years to guys who tried the socket thing. This is why I put the video on my web site. I am a Factory Certified Law Enforcment Armorer and cerrified on the 870 so this is good advise....... Others gave well meaning advise and you could follow it, be careful and their method work and not damge your weapon. Want to risk damage to a $230 receiver trying their way? If you do please remmember my web site as I sell new receivers.
If your weapon came from the factory with a Remington LE 2 shot extension then it does not have detents and you have no issue. If it had the detents we are talking about it would only take 4 rounds. If you bought it from some shop that is adding these accessories they may have installed it to a 4+1 HD and did not properly remove the detents. If that is the case, watch the video and remove the detents properly. to the guy with the socket stuck in his mag tube. Take the stock off, remove the trigger assembly. take a wooden dow about 3/8 to 1/2" and from the back end of the receiver run it in the mag tube and drive the socket out. Cehck to make sure you have not damaged the braising on the mag tube where it is mounted in the receiver, if not, Then go to the above web site watch the how to video and remove the detents correctly. |

Replacing the tube is a Factory repair as it has to be lined up perfect and braised correctly or you will have feed and function issues. If it is bent enough to cause a restriction have it replaced. If the damage is only a matter of appearence and it is functioning fine, I would leave it be........ doing anything else in the way of sizing, beating on it or bending can risk cracking the braising where it is mounted in the recevier, it could be a crack that you may not even see but this will FUBAR the weapon. A new receiver on the Remington parts list is $ 237.05 for the Express matte finish receiver or $237.05 for the police Parkerized Receiver, so if you have to get a new Reciever get the Police receiver as it is the same price.......or there is an Express Receiver without the detents for $237.05 also. Yes they all cost the same amount as there is only one 870 and they differ only by finish.

Yes, my computer guy is moving the how to videos to a u-tube account so they will load quicker. I can only load 30mb on my web site so I can't show some procedures, just have to talk them through... they will be back in Q-time till he gets them to the other then a link will be there. Once on the utube site I can re-shoot the videos and cover the entire process. A cleaning video is coming also....... I am also going to start keeping all the FUBAR stuff I get in that guys have tried on their own from information they get on some of these web sites. AR-15.com has the most knowlegable guys of any of the sites so I like this one, but even some stuff here is not good advice. So putting pictures of things like receivers with bent mag tubes and cracked braising mounts from guys trying to use dent pullers and sockets may make the point better and save some guys damage to their weapons....

Just did the dimple removal last week. Never having done this mod before, I was worried about doing more damage than good, so I dropped the extra $$ and picked up this reamer from Midway:
http://www.midwayusa.com/viewProduct/?productnumber=154173 With a little bit of oil and repeated adjustments to the reamer diameter, it only took about 15-20 minutes to completely remove the dimples. To me, it seemed like a fail-safe process b/c I could not turn the reamer if it was adjusted even slightly too wide. If I set it up to give just a little resistance, a few turns removed just enough material to get it spinning freely. Then it was time to open it up a little bit and do it all again. Now, can't feel the slightest trace of the dimples from the inside, and the outside of the tube looks exactly the same as it did before. Not sure what else I'm gonna use the reamer for, but even as a one-time tool, it was a good investment in my mind to make sure it was done right and avoid having to ship the gun back for a replacement tube. Maybe I'll just have to buy more dimpled 870s so I can justify dropping the coin for the reamer.

Thanks everyone for this thread, it's very helpful.
While the XS tool looks to be a very good option, I am cheap and decided to use a socket. Yes, you can damage your shotgun by using this method if you are not careful, but I had no problems. I think the key is to go slowly and avoid using too much force when driving the socket into the magazine tube. Also, be sure that the socket is not angled when you are pushing it down the magazine tube. I used a Craftsman 17mm, 1/2" drive socket with an extension. Using lots of oil I carefully and slowly drove the socket down the magazine tube. The socket pushed the detents out nicely. I left the socket in and using a small hammer I tapped on the outside of the tube to remove any ridges. The socket was stuck pretty good so I removed the stock and trigger assembly from the receiver and carefully drove the socket back out the end using several 3/8" extensions put together to the appropriate length. I have both a drill press and Dremel tool, but decided to try the socket method first before I did any drilling or sanding. My 870 came out perfectly and I will be ordering an extension and 18.5" barrel in the next couple of days. |

I believe you can get by without the detent spring and ball if your barrel is not equipped with it by simply putting a little Loctite or similar product on your magazine cap or extension when you install it. Also, you can wrap a rag around your magazine cap or extension so that it does not get damaged and then use a pair of pliers to tighten everything down. If someone has more first-hand experience with this please jump in. |

Go to www.brownells.com and in the search block enter "Wave Washer" it says for an 1100 but these work for any 11-87 or even 870. You get three for around $6 and they last a while. Simple install the forend, then the wave washer and screw you mag cap on.

I have a cheap set of files...some flat, some rounded. I filed down the dimples from the inside on my 11/87 and it works fine. While I have the power pools, I'm terrified of taking a powertool to a gun. The files are slower, but the end result is nice and smooth.

I just turned a cold roll bar a hair undersize of the mag tube.. Grease it and carefully use the bar like a dolly doing sheetmetal. 1/2 a dozen raps over each dimpled area and the dimples were gone. Touched up the ID with a brake cylinder hone and perfect.
Took about 15 minutes total. Not a fan of drillng them out, just leaves another place for debris to enter the tube. |

Glad I found this thread yesterday. I used the grinding attachment on my Dremel (it almost hurts to think that I actually used a Dremel on a gun) and filed off the nipples. I used a hand file to smooth out the last little bit and it funtioned flawlessly in a controlled environment. The read test will be in 2 weeks when it makes it's public debut at my local 3 gun match.
Thanks ARFCOM. |

Decision decisions!
HTR. ETA: interrogative. Wouldn't you have to hit on the socket -pretty damn hard- to actually crack the braising? I went with a combination of the two methods and it worked out perfectly! Checked for cracks on the braising with a mag glass, no cracks at all, but then I went with really small taps, used a lot of oil, worked my way up in socket size, and used some common sense while attempting this. Function check, 100%. Result: 
Really happy. |
