Aimpoint Acro C-2 3.5 MOA — Fully Enclosed Red Dot Reflex Sight
Overview
The Aimpoint Acro C-2 3.5 MOA is a compact, fully enclosed red dot sight engineered to endure the demanding use of semi-automatic pistols, carbines, shotguns, and rifles. It combines the proven ACRO closed-emitter design, a CR2032 battery, and a 3.5 MOA red dot.
The Acro C-2 is designed for fast and intuitive use. Its three-dimensional orientation supports quick dot alignment in the viewing window and can shorten the learning curve for new users. Its compact footprint suits optic-ready pistols, long guns, and secondary mounting positions on magnified optics.
3.5 MOA Red Dot
The 3.5 MOA red dot provides a versatile balance between immediate visibility and practical aiming precision. It is suitable for fast target acquisition while remaining fine enough for dynamic use across different distances.
The sight operates at 1x, with no magnification, unlimited eye relief, and a 15 × 15 mm clear aperture. It is operationally parallax-free, so exact eye centering is not required during normal use.
Fully Enclosed Design
The Acro C-2 optical channel is fully enclosed and sealed against environmental elements and contaminants. This architecture protects the LED emitter and reflective lens from dust, moisture, and debris that may affect open-emitter optics.
Hardened front and rear lenses protect the optical components. Recessed edges accept flip-up lens covers, available separately, for use on carbines, shotguns, or rifles.
Durability and Housing
The high-strength 7075-T6 aluminum housing features a non-reflective, semi-matte anodized finish. Its ultra-compact, streamlined profile also helps facilitate holster draw when mounted on a pistol.
The Acro C-2 has been tested on a .40 S&W pistol slide for more than 20,000 rounds. It withstands G-force shock, vibration, temperature changes, humidity, and occasional contamination from weapon cleaners, lubricants, fuels, and insect repellents.
Battery Life and Controls
Powered by one 3 V CR2032 lithium battery, the sight offers up to 50,000 hours, or five years, of continuous use at daylight setting 6, at 15,000 lux and room temperature. The quick-access battery cap allows battery replacement without removing the sight from the pistol.
Digital push buttons are easy to use with gloves. They provide 10 brightness settings: two settings compatible with night vision devices and eight daylight settings, including one extra-bright level. The startup setting is position 7 of 10.
Mounting and Zeroing
The integrated Acro interface is compatible with mounting plates for most optic-ready pistols as well as a wide range of carbine, shotgun, and rifle solutions. With an appropriate Micro interface mount plate, the sight can also be used with all MICRO mounts.
Windage and elevation adjustments are flush-mounted to reduce the likelihood of unintended changes. The clicks are tactile and audible, and zeroing is performed with the supplied Aimpoint T10 tool. Adjustment range is ±1 m at 100 m, with each click representing 20 mm at 100 m.
Night Vision and Environment
The Acro C-2 is compatible with night vision devices through its two NVD settings. Its lenses use multi-layer anti-reflex coatings and provide average light transmission of 60% from 420 to 700 nm.
The sight is submersible to 5 m / 15 ft and operates from -30 °C to +60 °C. It remains operable during and after cyclic humidity exposure up to 95% relative humidity.
