The Aimpoint ACRO P-2 is a Swedish enclosed emitter, developed by Aimpoint AB and marketed since 2021. Designed specifically for pistol mounting, it represents the evolution of the ACRO P-1 model and has established itself as the gold standard in the category of closed-back micro red dots for handguns.
History and Development of the Aimpoint ACRO P-2
Aimpoint, a Swedish company founded in 1974 and a pioneer in red dot technology, has launched the Advanced Compact Reflex Optic (ACRO) program to meet the growing demand for compact red dot sights for pistols. The first model, the ACRO P-1, was introduced in 2019 and marked a breakthrough in the market by offering a fully enclosed optical channel, protecting the LED emitter and reflective lens from any external contamination.
The P-2, launched in 2021, is a major improvement on the P-1. The most significant change is the adoption of a CR2032 battery, larger than the CR1225 of the P-1, allowing for more than doubling the range. Aimpoint has also revised the LED diode technology for better energy efficiency, bringing the total battery life to five years of continuous use (50,000 hours). The housing has been reinforced with hard-anodized 7075-T6 aluminum, and the waterproofing improved to achieve submersibility at a depth of 35 meters.

Operation and Technical Particularities
The Aimpoint ACRO P-2 works on the principle of the LED reflex collimator. An LED emitter projects a red dot onto a treated lens that reflects it back to the shooter’s eye, creating the illusion of a dot floating in space to infinity. The system is operationally parallax-free, which means that the dot remains aligned with the barrel axis regardless of the position of the eye in relation to the optics.
The major feature of the P-2 is its fully enclosed optical channel. Unlike open red dots like the Trijicon RMR or Holosun 507C, the LED emitter and lens are protected by a sealed housing, making it impossible to interfere with rain, mud, sand, snow, or any other environmental contaminants. This closed design offers a decisive advantage for professional users operating in harsh conditions.
The P-2 has been tested and validated to withstand the extreme shocks generated by more than 20,000 rounds fired in .40 S&W caliber, which produces approximately 7,400 G of force per shot, nearly double the size of a standard 9 mm. This exceptional ruggedness makes it a preferred choice for law enforcement and the military.
Variants and Versions
The ACRO P-2 is available in several configurations. The standard version offers a 3.5 MOA point, ideal for versatile use combining acquisition speed and accuracy. A 2.5 MOA version is available for shooters looking for increased accuracy from a distance. Finally, a 9 MOA version is offered for situations requiring ultra-fast dot acquisition. In terms of finishes, the P-2 is available in standard black, Sniper Grey and FDE (Flat Dark Earth), allowing it to adapt to different weapon configurations and tactical environments.
Users and Professional Adoption
The Aimpoint ACRO P-2 is adopted by many law enforcement units and special forces around the world. Several police departments in the United States have incorporated it as a standard optic on their service weapons. In Europe, various intervention units use it on pistols such as the Glock 17, the Glock 19 or the SIG Sauer P320. The P-2 is also very popular in the dynamic sport shooting community (IPSC/USPSA) and among demanding civilian shooters who are looking for the best possible reliability for their pistol optics.
Civil Possession in Switzerland
In Switzerland, the Aimpoint ACRO P-2 is an optical accessory freely available for purchase, without the need for a specific permit for the lens itself. It can be acquired from specialized gunsmiths and shooter accessory retailers. However, mounting it on a pistol requires that the weapon itself be held in accordance with the Federal Weapons Act (Arms Act), i.e. with a weapons acquisition permit issued by the competent cantonal authority. The conditions include: being at least 18 years old, not being under general guardianship, and not presenting a reason for refusal within the meaning of Art. 8 (2) Arms Act.
Conclusion
The Aimpoint ACRO P-2 redefined the industry standard for red dot pistol sights. Thanks to its closed optical channel, five-year battery life, proven robustness and exceptional waterproofing, it has established itself as the benchmark against which all other handgun red dots are compared. Its adoption by many professional forces around the world is a testament to its reliability and performance in the most demanding conditions.
