The Magpul Rail Light Mount fits on 1913 picatinny rails and comes in
both left and right side versions. It also integrates with Magpul XTM
panels. This mount position the weapon light high and cantilevered
forward at the 11 or 1 o'clock position to allow for a better supported
hand position while keeping the light tucked in and close the bore to
minimize barrel shadow. This will accommodate flashlights with a tube
diameter between 0.75" and 1.03" inches in diameter. The right side
mount will position the light in the one o'clock position.
