Aimpoint PRO

Install the DL1/3N Battery

1. 01

   Open the battery cap

   Confirm the weapon is unloaded and the safety selector is on safe, then turn the battery cap counterclockwise by hand until it comes free.

2. 02

   Check the o-ring

   Inspect that the o-ring is present, seated, and undamaged. Aimpoint's caution is direct: a missing or damaged o-ring lets water leak into the battery compartment.

3. 03

   Seat the cell positive end toward the cap

   Insert the 2L76 or DL1/3N cell with the positive (+) end facing the cap. A reversed cell is the second item on Aimpoint's own troubleshooting list for a dot that will not appear.

4. 04

   Hand tighten the cap and verify the dot

   Turn the cap clockwise until snug, by hand only, since the manual warns that using tools could damage the equipment. Then rotate the rotary switch clockwise and confirm the red dot lights.

Mount the PRO with the QRP2 Torque Knob

1. 01

   Pick a clean rail slot

   Select a groove on the Picatinny rail that puts the sight where you want it, and confirm the groove is undamaged and free of dirt and sand. Grit in the slot is what lets a clamped mount shift later.

2. 02

   Open the torque knob

   Turn the torque knob counterclockwise until the clamp opens far enough for the mount to drop over the rail.

3. 03

   Seat the mount and push it forward

   Install the mount and sight on the rail, then push the sight and mount forward toward the muzzle so the recoil stop contacts the side of the groove. Recoil drives the sight rearward, so preloading it forward is what holds the zero.

4. 04

   Tighten until the knob snaps twice

   Grab only the checkered portion of the knob and turn it clockwise until it snaps twice. Two snaps is the spec that means the mount is secured to the rail.

5. 05

   Retighten after the first rounds

   Test fire the weapon and retighten the torque knob after a few rounds if necessary, then run the zeroing procedure.

Zero the Aimpoint PRO

1. 01

   Open the covers and set brightness

   Open the front and rear lens covers, turn the rotary switch clockwise until the dot has enough intensity to contrast against the target, then remove both adjustment screw covers.

2. 02

   Correct elevation

   Turn the elevation screw on top of the tube counterclockwise to move point of impact up and clockwise to move it down. At 100 yards each click is 1/2 inch, so a group printing 2 inches low takes 4 clicks counterclockwise.

3. 03

   Correct windage

   Turn the windage screw on the right side counterclockwise to move point of impact right and clockwise to move it left. A coin, screwdriver, knife, or empty cartridge casing fits the slot.

4. 04

   Confirm with a three-shot group

   Fire at least three shots at a zeroing target, check the impact points, and repeat the correction until the group centers. After the initial firing, confirm the mount and sight are still secure.

5. 05

   Reseal the sight

   Reinstall both adjustment screw covers hand tight. They are part of the water seal, not dust caps.
