2. Select the left outer rail assembly, rotating it so you face the mid rail and the outer rail is facing away from you.
3. Rotate the mid rail release switch lever, then extend the mid rail until it locks.
4. If the distance you measured is not between the default 34 and 35 inches, use a #2 Phillips-head screwdriver to remove
and set aside all four rear mount bracket setscrews.
