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 2mm allen key through the access hole but do not remove the screws, leave them in position as shown below.

     

2-1 If you have fully removed the screws, insert them into position through the eye shaped opening. Once in the hole give it a slight shake so it drops all the way in. (it also works to hold the wheel so the screw is upright and tap the bottom edge lightly against a hard surface.)

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. (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 the half with the brass heat set inserts onto the adapter as pictured. Adapter, matte side out, parallax wheel flat side out.

5. Place second half of wheel with screws on adapter, again flat side out. Insert your 2mm allen key through the access hole to reach the screw and tighten each side down.

6.The screws should be snugged until the gap between the two halves is closed. You can give a very slight turn after the gap closes but do not over tighten them.

Installation is complete.
