Description
625 lumen fixed-mount long gun light with an integrated rail clamp for MIL-STD-1913 (Picatinny) or M-LOK compatible rails, for professional rifle and shotgun users.
The ProTac Rail Mount 2 is a fixed-mount long gun light whose integrated rail clamp attaches to MIL-STD-1913 (Picatinny) rail or M-LOK compatible rails. It ships in black with a remote pressure switch, tail cap switch, remote retaining clips, an M-LOK mount, mounting hardware and two CR123A lithium batteries.
On high it delivers 625 lumens and 22,000 candela with a 297 m beam for 2 hrs; the 60 lumen low gives 2,000 candela to 89 m for 21 hrs, and strobe runs 2.75 hours. Power comes from two CR123A lithium batteries.
The light is operated either by the remote switch with momentary/constant on operation or by the standard push-button tail switch, and TEN-TAP programming lets the user choose between three programs: high/strobe, high only or low/high. The body is 6000 series machined aircraft aluminium with an anodised finish and the lens is high-temperature, shock-mounted, AR coated, impact-resistant BOROFLOAT glass.
