View Full Version : Economical light mounts for a Mossberg 590?

For some time now I have wanted to mount a light on my 590. I tried a kit that mounted my Olight flashlight to the magazine tube with less than desirable results. The recoil from firing caused the mounting ring to put quit a bit of pressure against the back of the barrel mounting ring (Ie: what holds the barrel to the mag tube, in case Im using the wrong term, and made it damn near impossible to get the end retention nut off to remove the barrel. I have looked at the short picatinny rail mounts that attach to the bayonet lug, but have seen reviews on most of them saying theyre a very loose fit. I am not interested in the Surefire fore end, both due to cost and I do not like the feel of it, plus I do not want to grind off the bayonet lug.

Anyone have a suggestion for a more secure mounting method, or can suggest a good picatinny bayonet lug mount? It should be noted that I already have a dual-switch tailcap for Surefire 6P lights, the pressure pad, and a mount that will fit the 6P. I even have a spare 6P LED Defender that could be used for testing before committing to yet another $100 flashlight purchase.

Could you possibly find a short bit of Picatinny rail to mount on your forend, and then put the light on that?

I went with the Surefire forend myself, but I have the 6 shot 590A1, not the 9 shot I assume you have, so I don't have the bayonet lug to deal with.

Correct on the 9-shot.

I have thought about that, as well as the GG&G replacement fore-end with a rail built into the 3 o'clock position, but $100 is hard to swallow for the mount, THEN the trouble of changing it out. Honestly, I am not all that sure about what the best method for mounting a small rail to my factory fore end would be.

Some rails like the one that cane with my Knoxx collapsible stock has a recess and possible places to mount a short picatinny trail.

I just have the standard factory fore end, which I happen to like quite a bit. Im sure theres a way to add a short rail to it, Im just not sure what the simplest way would be.

Go to www.cdmgear.com (http://www.cdmgear.com) and check out the BMT mount. You can simply clamp it to the barrel or the mag tube and put the light in the other clamp, or you can go with the rail and use one scope ring to mount the light to the rail. Quality stuff, will take all the abuse you can give it.

I use a CDMGear MT clamp. This pic shows a cheap offset mount, but I ended up using 2 scope rngs until I can save up for a Larue mount. As Aippi said they are high quality parts. Just be sure not to overtighten them or the magazine follower can get stuck. I would get the new MOD-C clamp but I like being able to disassemble my weapon without having to remove the clamp.

Hm, the CDM mounts just list Mossberg 500. Will the different tube on the 9-shot 590 still work with those mounts? I would expect so, but I wanted to ask. They definitely look more secure than the cheap one I had before.

I got a three rail picatinny mount off ebay for a few bucks. Secures well with allen screws. Haven't had any problems with it so far. Just type in shotgun rail and you'll get a couple hundred results.

Laserlyte tri-rail mount. http://www.laserlyte.com/Gun_Sight_Accessories/%20OLD/tri-rail/index.htm

Have one on my 590 and it works great, very solid.

I've got a knoxx stock and one of these forends on the way for my 590, anyone know where I could find a piece of rail that would fit the knoxx forend?

Also Blitzer, about how old is that forend? I've seen some pics of the bottom of a knoxx forend and there are two brass threaded holes in the bottom where the indentation is. I'm curious if this is something new, or something they no longer put in their forends.

I have been in touch with Scott at CDM, and he has confirmed that the MT will work nicely with my light and shotgun. Ill be ordering one next week. $46 shipped would definitely qualify as economical for me. Thanks for the help, guys.

Looks like that will do it, thanks!

Post a pic when you get it if you don't mind. I'm in the same situation.

I have a TLR-1 which I think is great on a pistol, but too short to use on a shotgun without a remote switch, which takes the cost of the light and switch up to around $180 territory or so. With a remote switch, I could move it closer to the muzzle to prevent a shadow on the target from the barrel. The TLR-1 is mounted on a cdmgear.com BMT clamp with 3-slot rail.

My preference (since I don't want to buy a remote switch) is to use a longer flashlight (Surefire 6P, 6P clone, E2, Polytac LED, etc.) with a MOD-C clamp from cdmgear.com. With this set-up, the bezel of the light is close enough to the muzzle so that you don't get that nasty shadow on your target caused by the barrel. And you can still reach the switch with your hand on the front of the forend. Here's the set-up on my 18" Defender.

Barrel clamp $15. Streamlight polytac $40 Works great. I prefer it to the surefire forend on my 590a1

VERY belated bump. Due to some personal stuff that popped up, it has taken me two months, but I FINALLY ordered an MT clamp for my 590. I considered the BMT, but the MT was less expensive, and the CDM website showed photos of one in use on a 590. The visual reference made me feel very comfortable with using the MT mount, and I saved a few bucks. As soon as it arrives and I can get my 6P mounted, I will share photos.

Sounds good. Be sure to use the included rubber sleeve, and don't overtighten it. I overtightened mine and it trapped the mag follower behind the clamp. I didn't have the allen wrench with me at the range so I had to load all my rounds through the ejection port

Thanks for the heads up. It shipped out from Ft. Worth today, so I am hoping to have it by Friday.

The light and mount are set up and good to go. The magazine and follower are functioning just fine after a couple unload checks. I wont be able to life-fire test it for a few weeks, though.
Something I discovered while doing the install, however, was that my Danger Close low profile light mount does NOT fit on the CDM rail. The outer diameter of the DC mount is just a bit too wide on the inside to work with the light below the rail. Above the rail worked fine, but it put the light in my sight picture, and I did not like that. Fortunately, I still had a VTAC mount laying around, and I was able to use that to get the offset below the barrel.

I used a Choate forend with a Streamlight TLR-1 attached via rail.

If you have the bayonet lug this will work!
