    Hi Steve,
    I’m new at tactical equipment.
    What is the two units mounted on top of your rifle.
    One looks like some sort of red dot unit and the other ?????

    Great review! Thank you! If you want to go directly to strobe, you have to use the presure switch, I don’t know if it’s included. From everything I’ve read, the function will stay in the mode you last used until you change it. Of course, I could be completely wrong as I don’t have mine just yet. I’ll be putting it on a Sig M400. I can’t wait.

    UPDATE! I got my stoplite today. I don’t know if it’s newer, or older. I have only one port for the included pressure switch. The one I have uses 4 AA batteries, much cheaper then CR123’s. It does go straight to the last mode used with or without the pressure switch. Overall, I’m very satisfied.

      I just received the same one as Russell. I’m trying to figure out if it’s a really old or really new model. Everything I’ve read indicates that the 4AA battery powered lights are in the 300 lumen range, not the 700 lumen range. Aside from purposely blinding myself with the light, not sure if it’s possible to tell the difference between 300 and 700. Russell, does your battery cover have markings inside (look like presumably black Sharpie marker) indicating “+” and “-” locations? I’m thinking maybe I got a used one being sold as new??? I got mine on a gun auction website and those are always risky… I like the light but am disappointed that it takes AA vs. the CR123 batteries.

        Hi John,
        No, I don’t have any Sharpie marks on mine. The “+ and -” are stamped into the metal part where the springs come out. It looks like new, but who knows? I’m not finding any info on “New vs. Old” but, like I said I’m happy with the AA batteries, they’re cheaper, easier to find and add very little weight compared to the CR123 batteries to an already kind of heavy Sig M400. The light is plenty bright, 300 lumens, 700 lumens, what ever it has, I can’t look at
        it.

    I know this thread is a couple of months old but I thought I’d give my 2 cents… I don’t know if the old one actually puts out 700 lumens or not. It could be that the LED’s just have a 700 lumens rating. The LED’s in the new version have a 700 lumens rating but it only puts out 300-350 lumens due to the voltage. The LED’s in the newer version are made in the USA whereas the older LED’s were made in Japan. I have the latest version that has 2 screws that hold it to the rail, uses 4 AA’s and the laser switch is located on the back of the laser. The parts that clamp on the rail are plastic. I’m not sure, but it looks like (from photos) the old version may have aluminum parts because the clamping mechanism seems to be much thinner on the old version and they have only one screw. Since I’ve never seen an older version in person, I don’t know which one I would pick. There’s also more than two versions out there.

    Anyway, I’m happy with the one I have. It’s rock solid and very bright. I definitely recommend it to anyone looking for a grip with a light.

    I was seriously considering the Crimson Trace MVF-515 but I just could not justify the price difference and the fact that the MVF-515 is wider and neither the light nor the laser are under in-line with the barrel.

    I just received my STL-300J as well from Nelson Tactical (The AA version). A couple of things I did not see mentioned here. 1) The accessory power ports are gone(at least I cannot find them, and they are not mentioned in the manual either), I cannot find any on this model, and the remote pressure switch port is relocated to where they used to be. Not a big deal, didn’t have anything to plug into them anyway. 2) There is a “velcro accessory pouch” included, and I have absolutely no idea what “accessory” this is for, anyone else? It is not mentioned anywhere in the instructions other than the contents page. I assumed it was to carry the STL-300 on your belt when detached from the weapon, but I couldn’t figure out a way to securely hold the STL-300J in the pouch, only way I could figure was with the handle in the pouch, strap around the bottom, and the main assembly sticking out of the top, but it was not secure at all. There is a cut out on the strap that is about the same size as the laser assembly, but it is backwards, if the cutout was on the other side and the strap was a bit longer it would perhaps be perfect to hold the light assembly in the case with the handle would stick out backwards, and be very secure, but it wasn’t designed this way so obviously that will not work. What is this thing for, anyone know?

    One other thing I forgot to mention, the Sig version is now different from the iTAC-TDL1 in that the Sig takes 4 lithium AA batteries and boasts 700 lumen, while the iTAC-TDL1 takes 2 lithium AAs and claims 350 lumen. I don’t have any way to measure lumen output, but I agree with Steve, whatever the real output is, “As in “Aziz, LIGHT“ bright” sums it up, I am still seeing spots myself as I type this :).

        Ironic isn’t it? This accessory is supposed to blind your adversery, and being in my cave of a basement with no windows and low lighting, I am sure my pupils were dialated, so I can first had say it will work for its purpose. I am not sure why I tested it given you had already done so and it was clear without looking directly into it that it woud do its job, but I was tempted to do it anyway :). I certainly don’t taze or pepper spray myself to see if the products I have do what they claim (although while in the military I was tear gassed and can certainly say that stuff works!!), and I certainly wouldn’t shoot myself to check the effectiveness of the rounds I choose for SD (I rely on the ballistics jelly / phone book tests for that), so I have no idea why I volutarily blinded myself :).

    Almost all of the info on all of the websites is outdated; even the PDF owner’s manuals. I called iTAC and they said the iTAC and Sig models are identical except for the name branding. I got mine from here: http://www.hkparts.net/shop/pc/Tactical-Defense-Light-and-Vertical-Grip-ITAC-5p2512.htm. They were the only ones, at the time, that guaranteed they had the latest version and their images of the product are correct. Mine takes 4 AA’s. The person from iTAC said the lights put out 300-350 lumens. It’s plenty bright enough and the lower lumens dramatically increased the life span of the batteries. I don’t know how the light is supposed to go in the case. I never took the case out of the box because my light will stay on the gun.

    I just sighted the laser in, yesterday, at 50 yards. It’s pretty neat! I can put all shots in a 1.5” group even though the dot is pretty big (aprox. 2”wide x 4 ” high) at that distance. I’m really happy with my purchase but I think I’m going to call them to see how large the dot should be at that distance and why it’s oblong instead of round. How large is your dot at that distance?

      Yep, those pics are exactly what I got as well, thanks for the link. I just got mine, and don’t have a straight line distance in my house anywhere near 50 yards, and probably won’t be out the the range for at least another week or two (whenever Bar-Sto send my .40 P226ST and .40 P229 Equinox slides back with my 9MM conversion barrels fitted appropriately :/). I got all of my weapons within the last few weeks (great tax return, also got P220ST, Mossy 590 Special Purpose, etc.), and have yet to fire ANY of them, so am pretty antsy. My 556 is the 1st Gen ER model (later serial with US made BCG and gas cylinder assembly, not the Swiss ones :(), and I purchased them all used so have been spending the last few weeks getting accessories and getting them all cleaned up and/or refurbed by Sig (Sig customer service and custom shop is EXCELLENT BTW). My 556 has the old crap sites so I will be ordering the diopter / hooded front site from Sig tomorrow, and once that is in and mounted and I get my slides and barrels back from Bar-Sto, I plan on an all day range session to sight in all of my weapons (lasers, sights, etc.). Once I get back I will let you know my experience with the laser to see if it matches yours. I wouldn’t expect much for a laser in this price range along with the nice light and handle though… your experience is actually much better than I expected. I have an assortment of lasers from Lasermax, Crimson Trace, Viridian, etc., and while the prices vary dramatically, so does the performance in line with the prices. For example, you can get a cheap holosight for $75-$200 which will work, but typically the reticle is blurry, odly shaped (vs. perfectly round), etc. Or you can get an EOTech, where the reticle(s) are razer sharp and the parallax free feature actually works, but those will cost you a minimum of $500 new. Same with EOTech optics to mate with the holosight like the 3X that Steve has performs VERY well but they aren’t cheap… you get what you pay for.

        Yea, I know you get what you pay for. I bought the iTAC just for the light. Since this is the first laser sight I’ve owned, I didn’t know what to expect as far as dot size at different yardage. Your right about the EOTechs. I’ve got the EOTech EXPS2-0 on the same gun and I love it. I never imagined how much of an improvement it would be over iron sights. Worth every penny and I highly recommend it.

          If it makes you feel better, even my $300 Viridian green laser isn’t much good past 75 yds, and the diameter of the spot is probably about 1/2″ or more, but I don’t care because it is a pistol laser and I don’t see myself using it for anywhere close to 75 yard shots in comp or SD. I don’t think lasers are meant for long distance (past 40-50 yds, ideal at <25 yds) anyway, especially for rifles, although I haven't looked for long range lasers either. IMO optics are better for much more than 40 yards(while still being excellent for closer of course), like your lovely EOTech, I am assuming you agree since you ponied up for one. So the performance you are reporting is actually excellent considering the price paid for this piece of equipment. I paid ~$100 for each of my Lasermax LMS-MICRO lasers for a couple of my pistols that perform just about as well… maybe, haven't tried them past 40yd, and at that range they weren't great. Hell, I paid almost the same price of this grip for a Fenix (the TK41) tac light that is also rated at 700 lumen, although that one is probably closer to its rated output, but still. All in all based on what you have reported on the performance of the laser, this is one heck of a deal, I think in this case we got much more than what we paid for :).

          BTW, while I have used EOTech's and loved them, I do not yet own one for my 556. Given I only paid $850 for my 556 ER used (with probably 300 rds through it and in fine condition), the EOTech combo I want will cost a bit more than the rifle itself (EOTech holo with flip to the side 3X magnifier, or even cooler 3X-9X magnifier if they make one :)), hopefully I can configure to cowitness with the Sig diopter/hooded sight combo too. As it is I have almost spent $800 in accessories for it: this grip, 3 Magpul PMag 30RD clips, 10 40 rd "mil spec" steel mags (purely for storage if the SHTF or for plinking where I don't want to deal with reloading at the range, they were only $9 each so wny not :)), Swiss 551 pin to replace the PITA front double screw takedown pin, the nicer Sig sights, bipod, hinge to make my stock foldable, sling, a couple of different cases, and on and on. When buying one of these things stock, it is just the beginning I guess, where in my case the rifle will have cost me alot less than everything I put on it :).

    FYI, if you are new to the AR platform (whether traditional, 556, etc.), put some more time into reading, research, etc. and figuring out what your end goal rifle will be, which will be based on why you purchased it (competition, sporting, zombie invasion preparedness, whatever), vs. just starting to buy gadgets (like I did). In the case of this particular accessory, now that I have taken it to the range a few times and thought about where I wanted it to end up, while really cool, this item for me is now useless :(. This is because for my use (comp), I need a tripod, and I also need to be able to hold in a standing position for long periods of time so need to be comfortable. So, I got a Grip Pod (awesome) so that I would have a bipod when needed, and it stores in the vertible grip when not so I don’t lose verticle grip. Then I installed Magpul angeld grip behind that for better weapon mounting and control, along with better comfort for long periods of shooting (also AWESOME). Finally, I got the diopter/hooded sight set for swiss competition, and a red dot that co witnesses when I am not competing (Swiss only allows iron sights). Finally, I got an EOTech 552 Milspec Holo for combat type comp. Basically, I have no room on the bottom rail for this neat thing because of the Grip Pod and Magpul Angled Foregrip, I have no need for the later given either the iron sights for Swiss, or the red dot and EOTech for combat sim. For the tac light, found better options that are more flexible, where I can use a picatinny torch mount on a side rail with a quick release, and reuse one of my much better torches that I would be carrying anyway (any one of a number from my torch collection from very small 50 lumen to the biggest that would make sense, my Fenix TK41, where I have an 85W HID flashlight (not spotlight) form factor, that is around 8000 lumens, but that is a bit big, and I think weighs at least half of what my 556 does :). Finally, relocating the optics and light(s) to the side/top rails allows me to mount a bayonet without interfering with the throw patterns/visibility.

    I am not saying that this isn’t a great accessory, because it certainly is, just saying to make sure you have your end goal in mind before you start buying accessories, or you may end up extra $ on stuff that you cannot use. It is super easy to do this when you get a new rifle (especially AR15 type platform, there are SO MANY options :)), just takes a bit of discipline before hitting that “submit order” button ;).

    1. Great advice, Mike. Knowing why you “need” something is the most important part of the pre-purchase decision. :)

    Just fired up my STL-300J. The ‘reflection’ off the carpeted floor was enough to convince me never to look directly into the lens while it’s on.

    I want to know if you’ve had any issue removing the terminal plug for the pressure switch. Mine snapped in fine and is solid and works well but I can’t get it out. I don’t want to take the needle nose pliers to it yet. Attempts so far have started peeling back the rubber sheath on the plug. I’d appreciate your input if you have any tips or have had the same problem disconnecting it.

    Steve, is the STOPLITE(TM) STL-300J compatible with the Sig 551-A1?

    Anyone know the length of the mounting surface? Trying to figure out how much rail length I would need if I got this.
