The OpticsPlanet Exclusive Fortis Manufacturing F1TM Optics Mount is for red dots that use the Aimpoint Micro footprint. The Sightmark Mini Shot series red dots come with different footprints depending on the model you are talking about. The Sightmark Mini Shot M-Spec and Pro-Spec use the Docter/Noblex footprint. The Sightmark Mini Shot A-Spec uses the Shield footprint. None of these models will work with the OpticsPlanet Exclusive Fortis Manufacturing F1TM Optics Mount.
The OpticsPlanet Exclusive Fortis Manufacturing F1TM Optics Mount works with red dots using the Aimpoint Micro mounting footprint. The Sig Romeo 7 does not use that mounting footprint and will not work on this mount. The Primary Arms The SLx 3x21mm Micro Magnifier uses a 30mm ring or ring mount and will not fit the OpticsPlanet Exclusive Fortis Manufacturing F1TM Optics Mount either. We don't have an aftermarket mount to fit the Sig Romeo7 but the mount at the link below will work with the Primary Arms Magnifier.

Answering my own question cause I bought it anyways, yes it will.
No. The OpticsPlanet Exclusive Fortis Manufacturing F1TM Optics Mount is designed for T1/T2 style optics. The Aimpoint Pro will use 30mm tube ring mounts like s standard rifle scope. I would recommend a dedicated Aimpoint Pro mount from Midwest Industries or American Defense Manufacturing. You can find both mounts using the link below.

The OpticsPlanet Exclusive Fortis Manufacturing F1TM Optics Mount will not work for the Holosun 509T. You have 2 different options for the 509T. You can use the included RMR adaptor plate with your optic and use an RMR picatinny rail mount. Or you can get the mount from American Defense Manufacturing and Reptilia that directly mounts to the 509T. You can find that mount using the following link:

No it will not.
Yes, this mount is compatible with that optic.
The measured height of this mount is 0.955".
Yes, this mount is compatible with that optic.
No, the Holosun 510 would mount direct to the picatinny rail. This mount would not work with that optic.
