The Viking Tactics Light Mount was designed to give the shooter a lightweight, versatile option to mount a light on any Picatinny or Weaver rail system. The improved Viking Tactics Light Mount allows mounting with a .80 or 1" diameter and fits the VTAC-L4, SurefireTM G2 Nitrolon Executive Series and many others. The Viking Tactics Light Mount also 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.
