Description
Fixed-mount long gun light for Picatinny or M-LOK® compatible rails, with TEN-TAP® programmable output.
The ProTac Rail Mount 2 is a 625-lumen, fixed-mount long gun light for Picatinny or M-LOK® compatible rails, producing 22,000 candela for a 297 m beam distance on high (2-hour run time) and 60 lumens/2,000 candela/89 m on low (21-hour run time), powered by two CR123A lithium batteries.
TEN-TAP® programming lets the user choose between high/strobe, high only, or low/high operating modes, and the light can be run from either a remote switch with momentary/constant-on operation or a standard push-button tail switch.
