Aimpoint Acro P2 | Achieve Unwavering Confidence and Rapid Target Acquisition.
- The ACRO P-2 is a next-generation, fully enclosed red dot sight designed for extreme durability. Its primary benefit is providing faster, more accurate target acquisition while allowing the operator to remain fully situationally aware. The key differentiator is its sealed optical channel, which completely protects the LED emitter from mud, water, and debris, ensuring your aiming point is always present and functional regardless of environmental conditions.
- Extreme Durability and Reliability: The sight's housing is machined from 7075-T6 high-strength aluminum and is tested to withstand the shock and material stress of over 20,000 rounds of .40 S&W ammunition. It is submersible to 115 feet (35 meters), guaranteeing flawless operation in any environment.
- Extended Operational Readiness: A high-efficiency LED emitter provides an astonishing 50,000 hours (over 5 years) of constant-on power from a single CR2032 battery. This ensures your optic is always ready, eliminating the risk of power failure during a critical incident, and the battery can be replaced swiftly without removing the sight from your weapon.
- Confident Target Acquisition: The ACRO P-2 is operationally parallax-free, meaning the 3.5 MOA dot remains parallel to the bore regardless of your eye angle. This allows you to focus on the threat with both eyes open, which improves speed, accuracy, and confidence while maintaining complete situational awareness.
- Mission Versatility: Optimized for handguns, the ACRO P-2 is equally effective on carbines, shotguns, or as a backup sight on magnified scopes. It features ten brightness settings, including four compatible with night vision devices and six for daylight, ensuring optimal dot clarity in any lighting condition.

What is the battery life and what type of battery does it use?
The Aimpoint Acro P2 FDE, ACRO P-2 Black and ACROP2 Sniper Grey offer an exceptional battery life of 50,000 hours, which equates to over 5 years of constant-on power. This performance is achieved on daylight setting 6 with a single, common CR2032 battery. The battery can be replaced quickly without needing to remove the optic from the firearm.

Yes, the ACRO P-2 is fully night vision compatible. It features 10 brightness settings, 4 of which are designed for use with all generations of night vision devices. The remaining 6 settings are for daylight conditions, including one extra-bright setting for use in intense sunlight.
What is the advantage of a parallax-free optic?
The ACRO P-2 is an operationally parallax-free optic, which means the visible red dot remains parallel to the bore of your weapon regardless of the angle of your eye in relation to the sight. This is a critical advantage, as it allows the shooter to focus on the target with both eyes open, increasing situational awareness, confidence, and the speed of first-round hits. If the dot is on the target, you are on the target.
