NATO/Picatinny Rail for Kowa TSN-883 Spotting Scope

Use this to mount a red dot sight (reflex sight, finder) to your spotting scope.

Includes FreeCAD source file in case you'd like to modify the part.

Requires 2 pcs M4 x 20 screws with hex nuts to mount to scope.

On Usage

Advantages

The "top" mounting is considered the normal position, and the "left hand" mounting is the "hand over" position, which you can use when birding with other people who might be smaller than you and who wouldn't be able to view through the sight in the normal position without re-adjusting scope height.

(The "left hand" mounting can be turned into a "right hand" mounting by simply reversing the adapter.)

The "hand over" position is also great for use in hides, when the parallax of the sight in the normal position is too big to reliably avoid pointing the scope at the wall instead through the viewport.

Disadvantage

Stay-on case will not fit when mounting is installed. Check out https://www.thingiverse.com/thing:2822021 if you are looking for something which can be used with the stay-on case.
