Product Description The Streamlight ProTac Rail Mount VIR Pro is a professional-grade, gun-mounted tactical weapon light engineered to deliver both high-output visible white light and infrared (IR) illumination in a single, durable package. A head-mounted selector switch enables fast, intuitive transitions between IR and white light modes, while an integrated IR-to-white light safety cutoff prevents any unintentional visible illumination while operating in IR mode. Constructed from 6000 Series machined aircraft aluminum with a black anodized finish, this weapon light is IPX7-rated waterproof (with push-button switch installed) and tested to 2-meter impact resistance standards. Its multi-fuel design accepts one Streamlight SL-B26 USB rechargeable battery pack or two CR123A lithium batteries for flexible field use. The rail clamp mounts securely to MIL-STD-1913 (Picatinny) rails, and an included M-LOK adapter extends compatibility to M-LOK and M-LOK-compatible systems. The Jack-Cap tail cap delivers switch redundancy, supporting both push-button and remote pressure switch operation.
