That does not sound like an Aimpoint optic, so I cant help you there, but I hope you find what your looking for.
The Aimpoint Flip-up Lenscover for 2nd Generation Aimpoint Micro Sights will fit the Aimpoint Duty RDS.
The Aimpoint Flip-up Lenscover for 2nd Generation Aimpoint Micro Sights is not compatible with the Aimpoint Pro. It will only fit the CompM5 series & Micro series of sights.
Sorry, they will not. The H-1 and T-1 will not accept flip caps. This is a feature that was added with the Micro T-2 and H-2 series.
No, Aimpoint does not include the Holosun HS403R in its compatibility.
Aimpoint lists no accessories for the Micro S-1:
