We get a lot of questions about what type of mounting solutions are available/ appropriate for customers who purchase Aimpoint sights. As you know, there are a ton of aftermarket options. We don't have room to provide info on all of them, so we'll focus on a few... This article specifically addresses the Micro series of sights (T-1, H-1, and R-1).
These popular sights come with an integral mount that will allow the sight to be fixed to a Picatinny or Weaver rail with an Allen wrench screw. It is an 11mm height base, which is best suited for mounting to a shotgun rail or a mount designed to provide a backup sight to a magnified optic (like the TNVC S.A.R.). If you want to mount this sight onto an AR-style weapon, you must purchase a mount that will raise the optical sight path to the height of the iron sights.
