Description
High-lumen, weapon-mounted light powered by a USB-C-rechargeable SL-B50 battery pack, fitting long guns with MIL-STD-1913 rails.
The ProTac 2.0 Rail Mount is a high-performance weapon light producing 2,000 lumens/17,700 candela for a 266 m beam distance on high, without sacrificing run time, and 250 lumens/2,150 candela/93 m on low.
It's powered by a proprietary SL-B50 rechargeable battery pack that charges via USB-C inside or outside the light, so there's no need to remove it from the weapon. The tactical tail cap switch provides momentary and constant-on operation, plus a port for a remote pressure switch.
Key features
- 2,000-lumen output — 17,700 candela and a 266 m beam distance on high, without sacrificing run time.
- In-place USB-C charging — slide the sleeve back to access the charge port — no need to remove the light from the weapon.
- Tactical tail cap switch — momentary and constant-on operation, plus a port for a remote pressure switch.
