Both genuine Aimpoint, used excellent condition. In the first picture you can see the kit installed on Aimpoint T1 Micro (not included). Micro® Spacer High (39mm). Micro® Standard Mount for T-1 & T-2 Kit.
These come from Scalarworks LLC, a reputable optics accessory company. I own one of their Trijicon MRO/Mount combos, but for this particular build I got an Aimpoint T1 and needed a factory Low Profile mount and was very happy to grab this when "new factory mounts" cost 80$ on every other site.
