I would buy several. When the Aimpoint Micro was first introduced Aimpoint made or marketed many bases for sporting arms. Now not so much. If it doesn’t fit on a Picatinny 1913 rail good luck.
I would really like one for a 77 Express I have. Seems like that would make a Lott more sense, so to speak, than a telescopic sight on a DGR.
If you can live with a Burris Fastfire, Burris makes or did make a base that fit Ruger integral bases.
