What is the difference between the 6-slot, 9-slot, and 12-slot RMU mounts?

Yes. RMU mounts work with optics that use the Aimpoint Micro footprint, including models from Aimpoint, Holosun, and Sig Romeo.

Can I mount a magnifier with the RMU?

Yes. The RMU Mount for magnifiers is designed specifically to support rear-mounted magnifiers behind red dot optics.

What rail systems do the RMU mounts fit?

All RMU mounts are designed to work with standard Picatinny rail systems and are commonly used on AR-15, PCC, and tactical rifle platforms.
