Description
Multi-fuel long gun light combining visible white light with 940nm IR illumination, selectable via a head-mounted mode switch.
The ProTac Rail Mount VIR Pro delivers both visible white light and 940nm IR illumination, selectable via a head-mounted mode switch, producing up to 1,100 lumens/40,000 candela/400 m on white high, and 2,300mW on IR high.
An integrated cutoff prevents accidental activation of visible light while in IR mode, and the Jack-Cap® tail cap gives push-button or remote pressure switch redundancy. The rail clamp mounts securely to MIL-STD-1913 rails and includes an M-LOK adapter for M-LOK-compatible systems.
Key features
- Dual white light and IR — 940nm IR LED alongside the white LED, selected via a head-mounted mode switch.
- IR-to-white safety cutoff — an integrated cutoff prevents accidental activation of visible light while in IR mode.
- Jack-Cap® switch redundancy — push-button operation or remote pressure switch operation.
- TEN-TAP® programming — three user-selectable white/IR output programs.
- Multi-fuel power — runs on an SL-B26 rechargeable battery pack or two CR123A lithium batteries.
- Direct rail mount — mounts to MIL-STD-1913 rails, with an included M-LOK adapter for M-LOK-compatible systems.
Typical applications
- Long guns needing both visible white light and IR illumination
- Night-vision-compatible law enforcement and tactical platforms
- Users who want push-button and remote switch flexibility
