For SHOT 2015, Aimpoint has two newish products: the Aimpoint Carbine Optic (ACO) and the Aimpoint Micro T2. Both features improvement comes from the full size Aimpoint CompM4 red-dot sight.
The Micro T2 features an improved optical design. The 2nd front lens from Aimpoint’s dual-lens design is now slight angled. Aimpoint told me that the new feature helps to reduce flares and also focuses the dot more precisely.
The 2nd update is much welcome the compact flip-up covers. The Micro T2 will comes with the clear version that allow see through with or without illumination. The solid covers is available as optional add-on. The 3rd update is that the top turret is now protect with a metal bumpers like the CompM4.
The new Aimpoint ACO is defers from the popular Aimpoint PRO in two areas. The ACO uses a 2-oz lighter mount with a simple slotted nut mount. It also has the low profile turret and cap design that comes from the Aimpoint CompM4. Aimpoint said that may adds the low profile turrets to the PRO model too.
