Monstrum 100 Lumens Ultra-Compact Flashlight with 90 Degree Offset Rail Mount and Detachable Remote Pressure Switch

Really like this compact flashlight for my AR-15 carbine. It is nice and compact, about the size of a roll of Lifesaver candies. I didn't want a big oversize case or a blowtorch like light beam. The 100 lumens is enough light to illuminate and identify your target in the average room for a home defense situation without running the risk of overpowering light to blind yourself. As much as us guys believe the bigger the better, there is such a thing as too much light. It is also a big battery drain. Nice metal body that seems sturdily built. The threads for the battery enclosure tailcap are very fine so the user has to be extra cautious to not strip the threads. I also like the low profile picatinny bracket mount. It was easy to mount and adjust without completely removing the screw. Nice matte black finish that matches my carbine just perfect. I first mounted the light on the right side of my carbine but I did not like the shadows it casted from my barrel and BIUS (back-up iron sights) into my primary field of view. I moved it over to the left side where it does cast an edge of light on the BIUS but it is not noticeable in the viewable beam of light in front of me. In that position it is also located just above my Tacticon laser which allows a quick flip of the thumb back and forth from my laser to the light. This is very convenient with my grip style which rests my thumb across the top of the left rail. My only concern with the light is the durability and lifecycle of the tailcap power switch. It doesn't seem too cheap but this is where corners can be cut to reduce the cost of the light. The device does come with a remote pressure switch that I have elected not to use. I don't have any experience with these switches so I am unable to provide any feedback. I like my selection and think it is a great value for the apparent quality of the light. I have not shot with it yet so we will have to see how it holds up to the mechanical forces of firing. I will keep my review updated to reflect my experience.

First things first everybody. This is a $18 light, so for all the people giving it rough reviews what do you expect (a decent "legit" light for a rifle is going to be at least $150). Okay, now thats out of the way. This is a fantastic little light. The whole reason I bought this light was because of how small / compact it was. In fact, when it came in it was smaller that I even thought which is a good thing. I am actually super blown away about how "durable" it feels and additionally how durable the mounting bracket feels. For the money this is a good light. I did not attach the included (optional) thumb pad but the way its set up on my rifle its just as easy to reach the switch with out it. I would buy this light again (in fact I will buy another) and I do recommend it. Is it super duper bright? No, I mean look how small it is haha. But for the money, size and the standard "better than nothing" factor I absolutely like this light. Package came with (Light, Mounting Bracket, Allen Wrench, American Flag Decal, optional switch and a battery)

I'm giving this 4 stars because the light itself is great, the brightness is great, everything is great except the remote button. The button works but I didn't receive anything to mount that anywhere so it just hangs there. I'm probably gonna zip tie it to the front grip. It didn't come with any ties, double sided tape or Velcro, nothing. It's just a button that hangs out like my friends do. So I'm going to solve this problem with a zip tie and hope that works how I plan. Other than that, it also has a regular button like most flashlights have on the back with an on/off button but the remote button is more if a pressure switch which I like better because it doesn't require you to move that much and you can shut it off when needed just by lifting your thumb or finger from it. The light is a little smaller than I imagined but it's a beast for it's size. It's about 2" long maybe 3" tops and can mount itself to any picatinny rail. It sits offset so you don't have to worry about it blocking the scope or anything which is nice. I have a red dot sight on my bushmaster AR15 .223/5.56 and the light I mounted in front of it, can't even see the flashlight itself through the sight. As far as the beam and what you're looking at through the sight, it's awesome. I definitely recommend this for the cost and yes I tested the light, it's bright. My eye is still a little blinded from it after like 20 minutes lol I'd feel bad for someone if I blinded them with it... not really cause if that had to happen then they deserve atleast to be blinded.

I have yet to take this to the range, but I did install it on my rifle. Installation is simple and requires no instructions. Parts are aluminum but feel quite study. Light comes with a push button end cap and a remote tail switch. Tail switch does not come with an adhesive backing, but I personally like it better that way, as 99% of the time the glue only hold weakly and leaves sticky residue. I'll probably use some electrical tape to hold it on. The light is bright and sufficient for close to mid-range. You won't be illuminating the moon, but the lack of lumens is more than made up for by the small footprint, light weight, and the price. If it holds up at the range, I'll probably buy a few more. **UPDATE** I have put this on my rifle and sent at least 500 or so rounds downrange and it has held up phenomenally, I'm changing it from 4 stars to 5. I am very happy with this light.

smaller then expected, but better then hoped for. cant speak on durability or longevity, but get a couple batteries and dont throw your tool around, i assume it'll stand the test. worth it.

Bought this for my Mossberg 500 12 gauge. I like the small size, negligible weight, and low price. Mounted it easily and it tightened down well. First time at the range with it yesterday and the light flew straight out of its bracket after two or three rounds of 00 buckshot. The light still works and I’ve reinstalled it with a bit of inner tube between the light and the bracket to hold it in place, but I’m not hopeful. Screws are also starting to strip. We’ll see how it goes, but I suspect I’ll need to upgrade to something more robust.

Light is not bright at all can’t see anything with it
