The Viking Tactics Light Mount was designed to give the shooter a light-weight versatile option to mount a light on any Picatinny or Weaver rail system. This mount will allow you to mount any light with a 1? or slightly larger diameter. Even the inexpensive Surefire G2 Nitrolon will fit. The Viking Tactics Light Mount provides you a variety of mounting preferences. You can mount your light so that it is out of your field of view and activated by using a tape switch. You also may mount the light in such a manner allowing you to use the push button on the back of the light for activation.
