Description
I wanted to use an existing Bushnell Trophy red dot on a Hatsan Airtact. The Trophy was made for a picatinny mount and the Airtact had a 3/8" dovetail. I used portions of the mount profiles from LL77's "11mm dovetail adapter to 22mm picatinny" model in a new version done in Fusion 360. My version is longer and lower, using two M3 cap head screws for retension.
I printed it vertically (for better strength in the dovetail lips) with supports, using GF ASA.
Fusion 360 source and .STEP files are included.
