(included) to the threads on all
assembly screws and let sit until tacky
- approximately 2-3 minutes.
3.Determine orientation and location
where you plan to install the light on
your rail system.
4.Install your light to the GS-314x base
Picatinny rail using the factory mount
attached to your light. Check the
manufacturer’s specification for
recommended factory mount torque.
5.Install the mount onto your rail
system, insert screw / clamp assembly
and torque it down with the included
9/64ths hex key. Do not exceed
maximum torque of 40 inch pounds for
the cross bolt. If you do not have a
torque driver capable of measuring
inch pounds, simply finger tighten and
torque an additional 1⁄4 turn. Ignoring
this limit may damage your mount.
