Streamlight ProTac Rail Mount 1 | 350 Lumens | 88058

The Streamlight ProTac Rail Mount 1 is a low-profile, rail-mounted illumination tool designed for stable attachment to MIL-STD-1913 (Picatinny) rails. It accepts either one AA (alkaline or lithium) or one CR123A battery and offers selectable output levels plus a strobe option through TEN-TAP programming. The unit ships with a remote pressure switch, push-button tailcap switch, and an M-LOK mount for flexible installation.

Real-world applications include tactical training and low-light field use such as nighttime hunting or range work where a compact, durable beam and reliable mounting are required. The dual-fuel capability and multiple operating modes make it adaptable for extended outings or short sessions where battery availability varies.
