   4.8 stars I debated for a longtime between the rail mount 1 or the 2. I decided on the rail mount 1 for a few reasons: 1 – My operational environment (especially at night) is generally going to be under 100 yards 2 – I have a higher chance of operating inside of a building and having back splash issues than I do having to identify a target farther out. 3 – It is lighter weight. 4 – It takes up less space. After testing it under my conditions, I am happy with the rail mount 1 and am confident it will work well for me. If you are looking at longer ranges and more outside than inside I would recommend grabbing the rail mount 2. The quality of the light is excellent. It is a Streamlight, that speaks for itself. Everything works well and I like how it comes with multiple different options (remote pressure switch, tail cap, mounts, etc). It has multiple different modes but I find that to be somewhat pointless as under stress you will not be able to distinguish between modes (let alone switch between them). I immediately set mine to high only mode and haven’t tried anything else. I guess this might have an application if you are not using it as a weapon light or if all your other lights go down and you need the low power mode. I set up mine using a CR123 battery, high only mode, mounted to a rifle, and using the remote pressure switch. I tried the tail cap and it seems to work fine but I can’t speak to how well it holds up over time. Also, I never tried a AA battery in the light since the CR123 offers higher output but I like knowing I could use one if I have to. One of the main reasons I purchased this light over others is the ability to direct mount instead of having to use a ring or some other mounting system. My intention was to have something very low-profile, lightweight, using the least amount of parts and pieces that I could (less things to break). I am happy with the rail mount 1 and its integration into my system. I took the Picatinny screw mount system off to expose the two screw holes on body of the light. I then mounted the light to the Arisaka Inline Scout Mount M-Lok. This was the lowest profile mount I could find. I then mounted it directly to my M-LOK hand guard. I am very happy with the mount and how the light integrates. Using the appropriate amount of Loctite, it doesn’t move at all and stays very close to my rail. No problems there. — My biggest disappointment at first was the remote switch. It comes with these plastic Picatinny rail mount adapters (you can see them in the product pictures they look like little sections of rail road tracks) that the switch slides into, then the intention is you mount these to a Picatinny rail somewhere. Ok I tried this and lets do the math…width of your hand guard + Picatinny rail section + plastic Picatinny adapters + remote switch = this thing sticks out too far. Some people may like this but I personally do not understand it…I want my hand guard to be as low profile as possible. Luckily the fix to this problem was relatively simple – I just decided to mount the remote switch directly to my M-LOK hand guard. For other people who want to do this I’ll give you the steps. Step 1 – Purchase some M-LOK T-Nuts. Magpul Industries M-LOK T-Nut Replacement Set I recommend buying the ones made by Magpul but there are others out there if you want to try your luck with some off brand. Step 2 – Using some sort of tool, make the mounting holes on the remote switch bigger to match the size of your T-Nut screws. For some reason Streamlight made these holes too small to be useful but the remote switch is just plastic and it can be modified. I used a Dremel and CAREFULLY widened the holes (note: this will probably void your warranty if you care about things like that). As long as you are cautious not to get too close to the wiring or the actual button you should be fine (the plastic part you’re modifying is just the housing for the switch). Step 3 – Mount the switch directly to your hand guard. Be careful not to over tighten the screws since it is plastic. …and there you have it – a low-profile, fully functional, securely mounted, remote switch for your rail mount 1 (or 2). Take a look at the pics. I am very happy with mine and it doesn’t move around at all! After this slight modification to the remote switch, I can give 4.8 stars. Streamlight could make this light better by offering a better mounting system for the remote switch (or just ship it with bigger holes) but given the value of the light I think they did a good job. Overall, I am very happy.

   I own two of these fine lights and will be buying a third shortly. The ability to use AA in emergency and the Rock solid quality backed by lifetime warranty. Any issues email streamlight and they take care you.

   It’s durable and reliable, everything you would expect from Streamlight. Unlike other brands that offer dual power with a sleeve to make up the size difference of the batteries, Streamlight uses an ingenious system of a spring and buffer to adapt to AA or CR123 batteries. Great light for any CQB rifle set up. There’s enough to light up the target without blinding you from white walls. The included tape switch is positive and easy to trigger, it also has a second button to allow for always on/momentary. Perfect alternative for the Surefire Scout light, it has the same footprint as Surefire lights so you can use any existing Surefire Scout mount on the market.

   Fantastic light for the price!

   I already knew I was going to to get the bulky mount. I was NOT expecting 1 each – 350 lumen light.
   Very misleading item description.
   I read 1350 lumen light. I will not forget this..

   Don’t have anything to say about the light mount as I’ve put my in a scout-type mount. The light seems to be working out so far for my shotgun. I wish they had a product with a smaller tube and head, but this is acceptable.

   I am not a tier 1 operator and neither are you more than likely. That being said, This comes with everything an average sheepdog civilian operator needs. Picatinny and M-lok mounting options, pressure pad and mounting ability for the pressure pad, batteries and zip ties for wire management. Therefore, for the price and included accoutrements Streamlight has knocked it out of the park. For reference, I have owned the older version of these for a long time, way before they included M-lok attachment, and I find them to be very durable. The only thing they have ever failed on is the rubber around the wire for the pressure pad comes a little loose and shows the wire, but has never failed to still work. I find them to be bright enough for the distance I would ever take a shot in the dark anyway.
