Aimpoint ACRO P-2 3.5 MOA Enclosed Red Dot Sight

The Aimpoint ACRO P-2 has become the benchmark for enclosed-emitter pistol optics. Designed from the ground up for military, law enforcement, and defensive use, the ACRO P-2 delivers unmatched durability, outstanding battery life, and absolute reliability in any environment.

Unlike traditional open-emitter optics, the ACRO's fully enclosed design protects the emitter from water, mud, lint, dust, and debris, ensuring your dot is there when you need it most. Whether mounted on a pistol, rifle, shotgun, or used as an offset optic, the ACRO P-2 is built to withstand the harshest conditions imaginable.

Built for Hard Use

The ACRO P-2 wasn't designed for casual range trips—it was built for professional users whose equipment has to perform regardless of conditions.

Aimpoint engineered the ACRO to survive the repeated abuse of slide-mounted pistol use, including extensive testing exceeding 20,000 rounds of .40 S&W. The reinforced housing, protected lenses, and sealed optical channel keep the emitter isolated from rain, dirt, snow, mud, and everyday carry debris.

Whether you're carrying inside the waistband or working in harsh environments, the enclosed emitter provides peace of mind that an open-emitter optic simply can't match.

Designed Around Reliability

One of the biggest improvements over the original ACRO is the upgraded electronics and battery system.

The high-efficiency LED delivers a crisp 3.5 MOA aiming point while achieving an incredible five years of constant-on runtime from a single CR2032 battery.

Battery changes are simple and can be performed without removing the optic, allowing you to replace the battery without disturbing your zero.

The redesigned brightness controls also feature improved tactile feedback and are positioned to reduce accidental adjustments during everyday use.

Versatile Mounting Options

Although originally developed for handguns, the ACRO P-2 has become a favorite across multiple firearm platforms.

It's equally at home on:

• Duty and concealed carry pistols
• PCCs
• AR-15 rifles
• Shotguns
• Offset rifle optic setups
• Thermal and magnified optic combinations

Its compact footprint and exceptional durability make it one of the most versatile enclosed optics available today.

Our Thoughts

If your priority is absolute reliability, it's difficult to recommend anything over the Aimpoint ACRO P-2.

While there are excellent enclosed optics available today, the ACRO continues to set the standard for durability. The enclosed emitter eliminates one of the biggest weaknesses of traditional pistol red dots, ensuring the emitter stays protected from the dirt, lint, moisture, and debris that everyday carry pistols inevitably encounter.

The five-year battery life, top-tier construction, and Aimpoint's legendary reputation make this an optic you can truly trust.

Yes, it's larger than many open-emitter optics—but that's a tradeoff we're willing to make for a pistol that's built to perform in any environment. If you're building a duty gun, defensive pistol, or simply want one of the toughest pistol optics on the market, the Aimpoint ACRO P-2 is one of our highest recommendations.
