A good flashlight mount that is also priced properly!

I ordered two of these for mounting flashlights on AR15s. I had looked at a couple of other brands and they had a lot of complaints about not holding the flashlight tightly. These units are very nice and they perfectly fit my Nitecore MH12 flashlight. There are comments from a lot of reviewers about the finish being glossy but it looks good to me and it is not as glossy as the finish on my flashlight. If I get so that it bothers me I will just spray paint it with flat black paint. Heck once you turn on the flash light they will know where you are anyway.

The mount is well made and it fit tightly onto my flashlights. The two clam shell pieces are held into place with four Allen head screws. The mount fit tightly onto my Picatinny rails. The mounting hardware it a nut and you can use a wrench or a socket to tighten it down. There is also a hole in the nut and you can use the supplied Allen wrench to tighten down the four flashlight mounting screws and also the rail nut. I also added an extended control switch for the flashlight. Please excuse my pink photo background as I was using a plastic padded table cloth on a nice table to work on my guns.

This is a good product and it is priced properly.

I have shot many hundreds of rounds through my AR15 and I have had no issues with this flashlight mount.

The mount does the JOB, for the price gice it a try.

This mount is obviously NOT a LaRue and it doesn't cost as much. I put it on a very high-end M4 laughing the whole time. You have to get to the point when you choose function over fashion and stop buying all the high-end products companies throw at you. don't misunderstand that, If you are going into battle would you trust a cheap mount? Personally, I'm not sitting in Afganistan waiting for a firefight to break out. I'm more like waiting for a SHTF scenario"‹. I threw some Loctite on this and never looked back. Hundreds of rounds later it still keeps holding on. If you own an M4 you know there is very little recoil so seeing this mount still there is no big test of the quality. I cringe thinking about putting it on an 870 with 00 Buck. Time will tell I guess but for now, it fits my Picatinny rail perfectly. It feels solid and has held up over 500 rounds and being thrown around in the back of my truck. I'll shoot it until is breaks

Great Mount, Great value.

I've purchased one mount other than this to use with the exact same model flash light on another gun. This is the better mount, and, it's the cheaper mount. This mount, while made for a 1" flashlight, allows some flexibility. If you have a ridge or something of the sort that you need to clear or want to mount around, you can. The other I used has three rings at say, 1.2 inches at best. Very unforgiving. The center ring tightens and holds the light still. It works well but, has no tolerance for clearing a ridge in the center of the light, etc. 1" tube and that's it. This has a clamshell type design. You can take the top part off and reattached it at a position that clears any areas greater than 1". In fact the top piece has a gap in the center that I used to straddle such a ridge in my light. Well built, very solid and worth more than you'll pay. That should say it all.

DO NOT WASTE YOUR TIME. It is useless if you don't have it when you need it. Useless IR light mount. Can't mount the light on the scope without the ring mount. What good does it do to receive all the other equipment in three days if the mount comes by a slow boat from CHINA. I ordered a similar one from another company, received it and mounted my light I would return the one still in the middle of the Pacific just because of the stupidity, but it only cost 4 bucks. Buy the MONSTRUM Tactical Mount, took 3 days like a normal delivery should.

Overall machining and finish is good. But
by Chad Hensley (3 out of 5 stars)

Overall machining and finish is good. But, there were two problems. First, the clamping screws that were included were simply too short. With my flashlight installed, the screws only engaged about two threads. That meant it would easily strip. So I picked up some longer M4 screws only to find out the heads on the factory screws are thinner than standard M4's. Luckily I own a lathe and was able to turn the new screw heads down to size.

The other issue is that the nut that tightens the mount up on your handguard picatinny rail was drilled and tapped crooked. It wouldn't seat flat. I replaced that nut with a m4 nylon lock nut.

Like I said, the actual part was good, but the included hardware is crap.

Generic off set

Tactical light mount ... It is EXACTLY what it claims to be ! Read several reviews claiming theirs wasn't and that's unfortunate but i can only speak to mine and my experience ... Bought here on Amazon via Prime for $5 and of course free 2 day s&h which rocks ! Product arrived as expected and safely secured in it's plain white box sealed inside a larger brown box . Upon opening it i found the mount preassembled and in a ziploc baggy along with a small allen wrench . The unit i received was actually factually aluminum with steel hardware/screws and cleanly precisely milled/machined and fit my 1" bodied Streamlight TacPro HL like a glove ( also bought here on Amazon ) then mounted to my forward left 10 o'clock position rail simply and easily with the knurled knob which had holes drilled into it at 4 opposing positions with which you can use the provided allen key to torque down even tighter . Once done it was solid and secure and served it's purpose and i expect it will continue to do so for eternity ! Once at the range for the 1st time after mounting i found it's 1 and only flaw in my book . The main screw running across the Picatinny secured/clamped with the knurled knob was not touched with any thread lock as the 4 screws securing the actual light clamp were . After 3 mags run thru my AR it began to wobble and had come loose . I knew better but went let it go and upon returnin home that day removed it , wiped it down and added 2 drops of 242 blue loc-tite and haven't had an issue since so do yourself a justice and be sure to do the same ... Buy with confidence !

Nice and sturdy, arrived as shown

I bought this to mount a FourSevens Maelstrom MMX on my AR-15. The light fit perfectly and locked in tight with the provided hex wrench without adding any additional filler material in between the light and the mount. Actually, you could probably crank this thing down to the point where you would deform the body of the light if you got overzealous tightening things. I think something would break before the light ever came loose.

I have the Magpul MOE handguard with rails at 10, 2, and 6 o'clock positions. I placed the mount so the part that attaches to the rail is up, with the hole for the light on the bottom (I hope you can visualize) and mounted it at the front-most rail position. This placed the light almost right at the 3 o'clock position where I could easily access the tactical tailcap switch. I was really pleased with where the light ended up. The Maelstrom is a very big tactical light, and the bezel still had plenty of clearance. It sits just about the perfect distance from the handguard. Far enough that it can hold some of the larger, brighter lights, but not so far that it is obnoxious.

The material seemed nice and sturdy... not as heavy-duty as the YHM BUIS I have, but I think you'd break your light before you break the mount. The knurled thumb screw works nicely and I was able to get the mount tight without any tools, but there are holes around the circumference where you could stick a hex wrench or some other narrow, sturdy instrument in there and get some extra torque on it (would also be helpful if things expanded a little and the screw was too tight to remove with hands only).

I would call the finish satin. It isn't quite matte, but not very glossy either. I would be a lot more worried about the shiny, mirrored reflector on your tactical giving away your position than the mount.

Overall, it seems like a well-made, sturdy product, and I would buy another one if I ever bought another AR-15.

It's a buy it now or buy it later thing.

Just as long as you buy this item.

Great price for the same quality as the more expensive versions. I got two for the price of one. It's currently holding my Fenix PD22 the flashlight is smaller than the holder but I used rubber padding (FYI great household item to have) from the hardware store. It holds it tightly now but will update after some range testing. I prefer using this setup since I have several Fenix lights that will fit this mount. The flashlights uses rechargeble cr123 instead expensive button cells. The light output is higher and cheaper than holster type lights. It won't fit a holster but for a nightstand gun it's perfect.

One is/will be mounted on a handgun while the second one will be on a rifle.

While I can't rate its durability.....

I do like what I've seen from this mount so far. Considering the its low price, the fit feels snug, and on my Glock 17, it looks like it belong.

My only concern was clamping on my Nebo Redline flashlight. Part of the light to clamp on is just hair over one inch, and the bolts used to clamp the light almost seemed too short for the job. I believe the clamp is designed for flashlight 1" or smaller where they mount. I'm still not 100% confident about my set up, and will probably look into a smaller flashlight for the task.

Another small "con". Instead of the thumb nut shown in the product photo, mine came with a standard hex nut. This sucks a little bit. This nut is used to tighten and secure the mount onto the rail of the gun. I don't know if this was a cost saving measure, or if these clamps were falling off with a thumb wheel, because people couldn't tighten properly by hand......

All in all, I'm happy with the product I received. Good value.
*If you'd like to see how this mount look on a Glock, I did upload 3 pics. Hope it helps. :)

Used with a Olight M20-X Warrior
by Stanley Jou (4 out of 5 stars)

I like the offset of this mount vs the normal mount that is in line with the rail. The offset allows me to use my thumb to push the tail cap switch to turn on the light with either a vertical grip on a rifle or even just a pistol. Full size flashlight on a pistol looks a bit ridiculous but it works quite well. The strobe momentary switch on the side of the tail cap is also reachable from here as well. I prefer using my thumb to enable the light over using a pressure switch because I feel that it gives me more control and isolates movement to my finger rather than my whole hand to turn on the light.

As for the fit, it is pretty snug. I didn't abuse it to see how well it holds but from what I could tell, it wasn't going to move without breaking.

One downside is that you will have to remove the belt clip on the m20x to use the mount. And for an easier slip on and off use (without having to fully loosen the mount screws) you will also have to remove the cigar holder. Not a big deal but worth mentioning. Because of this though, I feel that I won't use this much unless I designate the light as a weapon light only.

Worth the money if you feel the way I feel stated above.
