Streamlight88066 ProTac Rail Mount HL-X 1000-Lumen Multi-Fuel Weapon Light with Remote Switch, Tail Switch, Clips, and CR123A Batteries, Box, Black

It’s very well-built, bright as hell, easy to mount, and just works quite well on my rifle. I’m freaking thrilled with it! The battery life is really impressive too, considering the scope and brightness of the light. The strobe function is awesome and easy to actuate too. I did a ton of research about rifle-mounted lights and these always came highly recommended. I now understand why.

This is my second Streamlight HL-X. The first one I purchased is the 88071, this is an 88066. I recommend going with the 88071 because it includes the Streamlight 18650 rechargeable battery - this model ships with two Streamlight CR123s. This was my fault, so I have not deducted any overall stars.The light itself has great output and is well constructed. Out of the box, you get the light, two batteries, a clicky tailcap, and a tape switch tailcap. It also comes with a piece of adhesive for the tailcap, two zip ties, and two rubber feet for attaching the tape switch to 1913 rails. My recommendation is to upgrade to a Cloud Defensive LCSMK2J tape switch mount, since the zip ties can get a bit unruly and the Cloud Defensive mount has better cable management. That being said, if you are just trying to get your firearm up and running, it is great that Streamlight includes a mounting solution. The tape switch itself is somewhat mushy but can be activated across the whole length of the switch, unlike some other options I have tried where you need to press directly in the middle. The constant activation button has a helpful shield around it to prevent unintentional activations, and I tend to mount my tape switches so that this button faces away from me.The Streamlight HL-X ships with a 1913 thumb screw mount installed in the box. This is an okay mount, but it is a bit on the bulky side. The HL-X is compatible with most Surefire Scout footprint mounts, so I replaced the included 1913 mount with a Magpul M-LOK offset Scout polymer mount and hardware from Arisaka defense. If you don't want to pay for the $3 in hardware, you can attach the 1913 thumb screw mount to the Magpul offset adapter as well since it has a slot for the cross bar.The main downside to the HL-X's mounting system is the screw body placement. Most Surefire Scout lights and other lights that use the same two hole mounting pattern bias the mounting holes to the rear of the light to move the light forward on the gun compared to the mount. Surefire does not do this - the holes are smack dab in the middle of the light body. Combine this with the already bulky nature of the Streamlight HL-X and you may have some packaging issues when trying to set up a weapon with limited rail space. I may eventually transition to a Haley Strategic Thorntail SBR mount to remedy this since it pushes the light even farther forward. I would simply go with a longer Arisaka in-line mount and put it on the 1:30 section of 1913 rail, but the screw hole location prevents you from using the Arisaka in-lines without modifying a hex key to tighten the hardware.Overall, for the price, I feel that this light, despite the bulk and mounting issues, is a solid contender for a carbine or shotgun. With some upgrades to accessories like a light mount and a tape switch mount I think the Streamlight HL-X will serve you well.

The Streamlight 88066 ProTac Rail Mount HL-X is an exceptional weapon light that delivers impressive performance! With a powerful 1000 lumens output, it provides bright illumination, making it perfect for tactical applications or home defense. I love the multi-fuel feature, allowing it to run on either CR123A batteries or a rechargeable battery, which adds to its versatility. The included remote switch and tail switch make it easy to operate, even in high-pressure situations. The sturdy construction ensures durability, and the sleek black design fits seamlessly on my firearm. If you're in need of a reliable and powerful weapon light, I highly recommend the ProTac Rail Mount HL-X!

I love this little light. This is the 3rd one I've purchased. It's easy to mount, the tape switch works great and it's super bright. Double press the switch and it strobes too.

I trust Streamlight as I have a TLR-7 and the build quality, fit and finish really impressed me for the price, and the brightness was very good (it’s bright enough that looking directly into it will nearly blind you temporarily). It also was great in how it attached, ease of use etc. I liked everything about it, so I went with Streamlight for this purchase as well.I have no complaints so far, it seems like a solid light and basically exactly what I expected (I haven’t used the switch, as I feel I can thumb the button just as easily with it on the left side, and won’t accidentally hit it). The brightness is just as strong as I expected as well.In regard to a review talking about getting a fake one, I did not (mid 2022).The build quality is just as I’d expect, it’s robust and the finish is very nice. It’s very easy to attach to a pic rail (if you have an MLOK guard you just need a little pic rail, they’re cheap), and it has a hand-tightening nut attaching it. The nut has a slot cut into it as well so you can use a tool (a knife, whatever fits) if you ever needed to loosen it if it seizes up a bit.The only thing that surprised me a bit was the size. It’s a little bigger than I expected and hoped for, but that’s why you should research before buying anything lol. It’s fine honestly, just a little larger than I realized. I would’ve preferred a slightly smaller/lighter light, but the fact that it’s big enough to be used by hand is probably a benefit anyway. I suppose it’s a normal size for a light of this nature, I have never owned one so it’s new for me. It looks a little big on the there in terms of aesthetics, that’s all.If anything goes wrong with it I’ll update. But as of now I recommend it and I definitely recommend Streamlight. I like their products.

For the price of this light it’s great. The light is programmable by tapping the pressure pad and you have 3 programmable options. The mounting hardware is durable. The pressure pad is plastic but works great for most applications. I don’t recommend buying used like I have because not all of the hardware to mount the light was there. But overall a good option for budget minded folks or getting into WML

Good mounting system for the light, the light itself is bright and has decent dispersion. The big plus is it's about half the price of Surefire.

Excellent weapon light. Comes with two mounting options. Pressure pad works great and is very responsive and comes with cable management system. Perfect for tactical use
