How do I know if my Remington 870 Express has the dimples that makes this mag extension not work well? Any kind of gunsmithing is beyond my skills.

The dimples are where the cap screws off the magazine tube..... Use a 3/16 drill bit to drill out the dimples then use some sand paper to smooth the metal down were you drilled the dimples out...... Very easy to do!

If you unscrew the magazine cap, there's a small black plastic spring retainer with a flathead slot in the center. To remove it, you have to push it down, turn 90 degrees, and then it comes out, either with a flathead or your finger. This is what's retained by the dimples, which you'll see at 12 and 6 o'clock punched from the outside in. I grinded mine down with a dremel tool, then cleaned and sprayed with matte black paint. You'll know you've grinded enough if you can drop the plastic retainer into the magazine tube without resistance or having to turn and key it.

Take the mag cap off and look in the end of the tube. You'll see the dimples if you have them

remove mag. cap and spring, feel inside the mag. tube for a raised area in the inside of the tube, this is the dimple. file it out with a half round file and smooth with 220 grit wet and dry sandpaper wrapped around the file. lightly oil the area with gun oil. then install the extension spring, cap and swivel, finished....

That is what I have it on. Your mag tube ends about 1-2" before the muzzle correct? Just make sure you get the one for the Remington because other guns have a different design for their end caps. It makes the gun just look nasty =-) In a good way

Your pardner is basically a Remington 870 clone. The kit does come with some adapters. Your guess is as good as mine whether it will work. Contact the manufacturer and confirm. If it doesnt work you can alwas return it.

I would advise you to buy a $20 suppresor/bore extension. This one is plastic and will not fit on most guns properly. In addition, the threading doesn't work with a metal barrel...the metal barrel eats it up. :)

The internal ratchet is in the cap. It is more like a thrust washer with small humps around it. The mating part is on the end of the magazine tube and it has teeth on it. When you screw the cap down you will feel the ratchet clicking as it is being tightened. There are differences in the 870 Wingmaster and the 870 Express. I found out the expensive way. The correct Uncle Mike's swivel set for the 870 Express is 1800-2 and it will specify 870 Express on the label. If it doesn't have 870 Express on the label then it is for the 870 Wingmaster and will not work on yours. Hope this helps you.

Sorry, have only used it on SR22 mags. It doesn't do well on these. I misspoke, I also used on .380 mags and it did well. Sorry I couldn't help.

I've shot a lot of rounds thru my 870 tactual without any problems. I check everything fairly often but don't recall any serious problems with it coming loose.

Put mine in today, not quite the mag drop I was hopping for. I have 22/45 lite, the mag still hangs a bit. Seems to be very little tolerances inside the mag well. Any one else having that issue ?

As far as I can tell, this clamp is designed to be used with two different diameters, as in a barrel and a flashlight. Also, there may not be enough clearance between barrel and magazine extension to allow the mount halves to come together. I have a magazine extension on a Mossberg shotgun and found that the clamp it came with actually pushed the extension out of alignment with the magazine. I took the clamp off and never had a problem with the magazine spring binding or shells getting stuck. The threads on the extension were more than strong enough to support it. If you are worried about the extension backing out, you can put a little nail polish on the threads, but that may cause you problems if you want to get it off. Just screw it on hand tight and that should be enough to keep it in place. Happy Shooting !!!!!!!

I put this on my 870 pump and it all fits(have to drill hole for the rear connect). I thought I was 100%, but went to shoot some clays and the front screw cap shown in the picture kepts coming loose every 20 shots or so. I would tighten it back up by hand, did not use a wrench, but it would slowly start coming loose. One time I shot my 870 pump and the entire firearm came apart. Everyont still gives me a hard time about it, but I do not think that would have happened with the original Remington cap. Still trying to decide if I should try to stick with it, or revert back to original Remington cap. I put this on my 870 pump and it all fits(have to drill hole for the rear connect).

In agreement with previous answers, the key is the location of the pins which are pretty much the same on all the trigger groups. I have not mounted one on an 870 Super Mag, but would not be hesitant to purchase one to mount.

Not exactly. I contacted TAPCO and they said some SKS have issues, but there is a fix and they sent me a diagram of the spots on the magazine that need to be sanded a bit. After sanding they worked fine. I was concerned that the sanding might effect my warranty and they said it would not.

It's up to you. I took that approach, put a small amount of Loctite on the end of the key, and it worked very well. Without Loctite (or equivalent product) no matter how you attach the unit it will shake loose after a couple of hundred rounds. As I regularly put 500 rounds of copper solid slug through my Remington 870 in a session, shaking loose wasn't a desirable trait. By the way, the buttstock I put on to replace the stock unit has a recoil spring that does a fabulous job of absorbing the recoil, otherwise my shoulder would be rather sore after a day's tactical session. With the spring stock I end the day without any discomfort at all. It's up to you. I took that approach, put a small amount of Loctite on the end of the key, and it worked very well.

I really don't know. I know when I bought it it said it would fit a Rem 870.........I guess I was specific enough cause I purchased a YOUTH EXPRESS 870.....and it did NOT fit. I have to have a gun smith grind it down to fit the stock.....nice job but initially, it was not a good fit. You would have to ck for specs on it. However that said..........it was much nicer, softer, more pliable than what came w/ the gun!

the compensator looked amazing on my 1911, it did not match up perfectly and i was ok with that. It was until i decide to chamber a round that i realized it stopped my slide from going all the way back and not allow a round to be fed . i have since then taken it off and have been too lazy to return it, i have a springfield 1911 champion.
