MOUNTING
The Sightmark Photon RT riescope requires 30mm scope rings (not included) for mounting. Mount the scope
per the scope ring manufacturer’s instructions. Do not perform a nal tightening of the rings prior to checking
eye relief and reticle alignment. Initially the riescope should still be able to move for and after and rotate when
installed in the rings.
To achieve maximum eye relief:
1. Turn the Photon RT on and focus the image. Set the riescope far forward in the rings and slowly move the
riescope closer to your eye. Stop moving the riescope once a full eld of view is visible.
2. Next rotate the scope to vertically align the crosshair. Use a reticle leveling tool if available.
3. Once alignment is complete, tighten the mounting ring’s screws evenly so the gap is even on both sides of the
scope. Do not over tighten.
Warning! If the riescope is not setup correctly with proper eye relief and is mounted too close to the shooter’s eye, it’s rearward motion due to rearm
recoil may cause injury to the shooter. To zero the scope, see section “One Shot Zeroing”.
