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.
