Streamlight ProTac Rail Mount 2 Weapon Light with Remote Switch & 2 CR123A Batteries - Aluminum Black

The Streamlight ProTac Rail Mount 2 is a versatile 625-lumen weapon light built for AR-15s, carbines, and any rifle or shotgun with MIL-STD-1913 (Picatinny) rails. This is the light for shooters who need real brightness without compromise—whether you're training at the range, hunting in low light, or running a duty setup. It delivers serious output (625 lumens on high, 60 lumens on low) with enough beam reach to light up a target 297 meters away, all backed by anodized aluminum construction tough enough for hard use.

What sets the ProTac Rail Mount 2 apart is flexibility. Streamlight's TEN-TAP programming gives you three modes to choose from: high with strobe, high only, or low and high. Run it from the included remote pressure switch for hands-free momentary or constant operation, or flip to the standard push-button tail cap if you prefer direct control. Two CR123A lithium batteries come in the box and deliver 2 hours of runtime on high, or stretch them to 18 hours running low. The remote switch setup is IPX4 rated; go with the tail cap switch and you get full IPX7 waterproofing to 1 meter for 30 minutes.

Installation is straightforward—the integrated rail clamp grips Picatinny securely without wobble, and Streamlight includes a remote retaining kit, M-LOK mount, double-sided tape, and zip ties so you can mount it however your setup demands. This is a no-fuss light that works hard and doesn't ask questions.

Specifications

Frequently Asked Questions

Will this light fit my AR-15 or carbine?

Yes. The ProTac Rail Mount 2 clamps directly to any MIL-STD-1913 Picatinny rail on rifles, shotguns, and carbines. It's also compatible with any firearm that has a Picatinny top or side rail.

What's the difference between the remote switch and the tail cap button?

The remote pressure switch lets you mount the light on the rail and control it from a separate switch mounted on the foregrip or handguard—great for hands-free operation or keeping your grip constant. The tail cap switch is mounted directly on the light body for simple pushbutton control. You get both in the box.

Are batteries included?

Yes. Two CR123A lithium batteries are included and ready to go.

Is this light waterproof?

It depends on which switch you use. With the standard tail cap button installed, the light is IPX7 waterproof (submersible to 1 meter for 30 minutes). With the remote pressure switch installed, it's rated IPX4 (splash resistant).
