1. Identify the proper orientation of the adapter as shown in the images below. Matte side faces away from the scope… to the left if you are behind the airgun.

2. Carefully take apart the 2 halves of the scope wheel by inserting a 2.5mm allen key through the access hole but do not remove the screws, leave them in position as shown below.

3. (HELIX) Place the adapter onto Parallax knob as shown in picture, ensure the contours of the adapter are aligned with the contours of the Parallax knob, and is centered over both ridges.

 

3-1. (TITAN/NEXUS) Place adapter onto Parallax knob as shown in picture, ensure the contours of the adapter are aligned with the contours of the Parallax knob, and is centered over the two inner ridges.

 

4. Once adapter is situated correctly place top half with the screws in place. The matte side of the adapter and the flat side of the 90mm Wheel should be facing outward as in the image below.

5.Angle the smaller section as in the image below, insert and rotate downward to align with the top section and the adapter. Once seated gently hold the adapter in place with one finger.

   

6.With your 2.5mm allen key snug the screws to tighten the 90mm Wheel around the adapter. We recommend alternating between the 2 screws to tighten things evenly.

7. Tighten the screws until the gap between the 2 wheel halves is closed as in the image below. You can give them a slight turn further, but do not overtighten them.

Installation is complete.
