In this article, Dr. Will Dabbs offers his opinions on the Aimpoint ACRO P-1 after spending some time on the range testing it out. The capable red dot sight offers a lot of benefits when used on your rifle or pistol. The company provided a loaner for this Aimpoint ACRO P-1 review.

The Aimpoint ACRO P-1 is the only fully enclosed micro red dot sight on the market today. ACRO stands for “Advanced Compact Reflex Optic”, and while lots of folks make optical sights these days, this one is tough enough to stand up to just about anything you could throw at it. But how did we get here?

In this photo, we see the writer mounted the red dot sight on his SAINT rifle for the Aimpoint ACRO P-1 review. The optic is mounted on a riser on the Picatinny rail. The rear iron sight is visible. — For this review, Dr. Will Dabbs mounted his Aimpoint ACRO P-1 on a Springfield Armory SAINT rifle. He found the optic was a true combat-grade red dot sight.

We Had It All Wrong

I grew up with the original Star Trek. Those three seasons running from 1966 through 1969 encompassed some 79 episodes ranging from ridiculous to sublime. Gene Roddenberry, the show’s overarching creative force, envisioned a sort of Wagon Train to the stars. Packing classic Western themes of adventure and rugged individualism in a setting made fresh by the ongoing space race, Star Trek became an instant period classic.

This image of Captain Kirk and Mr. Spock from the Star Trek television series shows how technology envisioned in the 1960s evolved into what we have today. — Star Trek was a prophetic television series in ways we failed to appreciate at the time. Image: Wikipedia

Star Trek proved to be a prescient vehicle of prophecy — it just wasn’t how we expected. What the world took from Star Trek wasn’t shuttle service to the stars. It was doors that opened automatically and an absolute revolution in microelectronics. Nowadays, every trip to Walmart starts with a door that opens of its own accord. Additionally, I carry a communicator-sized smartphone around in my pocket that will instantly connect me with Istanbul if I punch in the right combination of numbers.

Here, the author shows us the battery compartment on the reflex sight he is reviewing. Aimpoint uses a waterproof screw in cap that provides excellent water resistance to protect the sight's electronics. — Battery changes do not require dismounting or re-zeroing of the ACRO sight.

These microelectronics affect every aspect of our modern lives. Paranoid parents track their children, and children track their pizzas. I carry more computer power in my pocket than launched the space shuttle.

While this revolution fundamentally altered health care, travel, government and entertainment, it also changed the way we run our guns. When I was a soldier, we qualified with our weapons out as far as we could see over iron sights. Today, iron sights are just an afterthought to be used if your primary optic fails. Roddenberry would be proud.

Shown on a Springfield Armory SAINT AR-15 rifle the Aimpoint ACRO red dot sight makes accurate and precision shooting easy with all kinds of firearms - from a pistol or handgun to a carbine, rifle or shotgun. They are compativle with some holsters and make a lot of sense for anyone in the military or who is a hunter. — The Aimpoint ACRO is rugged enough to stand up to just about any situation you could imagine.

It took us a decade or two to grow comfortable with electronic optics on our rifles. Nowadays you really can’t eat at the cool kids’ table at the local range if you don’t have something battery-powered and sparkly perched atop your favorite black gun. Of late, however, we have also come to expect the same capabilities on our handguns.

What Is the ACRO P-1?

At its heart, the Aimpoint ACRO P-1 is a red dot reflex collimator 1X electronic sight. A red Light-Emitting Diode (LED) produces an aiming point via a small screen. With both eyes open, the aiming point projects out to infinity such that it seems to hover atop your target. Somehow the dot remains sharp and distinct at a distance where you need it rather than up close inside the sight where you don’t. I truly have no idea how they do that — but I’m glad they did.

The Aimpoint red dot sight is an improvement over iron sights but it does not provide magnification of a telescopic sight. When mounted on a firearm like the Springfield Armory Prodigy (which is a superior product to the SIG Sauer M17 - not our favorite gun) the optic uses the Picatinny rail on a carbine shotgun or other gun which is perfect for the shooting sports. It is also night vision compatible and can handle snappy handgun cartridges like the .40 S&W and 10mm Auto. Ammunition really doesn't impact this sight. — A waterproof pushbutton cycles the ACRO P-1 through ten brightness levels, four of which are NVG compatible. Image: Aimpoint

The sight zeroes with a small included wrench. Simple waterproof “up” and “down” arrows control intensity through 10 brightness settings. The ACRO P-1 is NVG compatible and projects a 3.5-MOA dot. The whole rig weighs a paltry 2.1 ounces.

You can exchange the battery in the ACRO without dismounting the sight or adversely affecting its zero. Expect 1.5 years of continuous operation out of a single CR1225 lithium battery on a typical daylight power setting. Make that eight years of continuous operation in NVG mode. The field of view is generous and uncluttered.

The optic performed well in the snow, rain, mud, sand and other matter including temperature extremes. Vibration did not negatively affect it and parallax was free of angle distortion. During daylight, target acquisition was easy as brightness was adjustable without any adapter. It also passed submersible testing. — The optic can be mounted on a pistol, or on a rifle like the SAINT with an appropriate riser mount.

Lots of folks make red dot sights that will do stuff like that. However, the ACRO will also thrive underwater down to 25 meters. The sight is rated for operation between -49 and +160 deg F as well. Sundry adaptor plates and mounts will set up your ACRO on a variety of popular handgun platforms as well as anything sporting a Picatinny rail. I chose to strap it to my Springfield Armory SAINT rifle.

The SAINT is a high-end black rifle at a mid-range price. Featuring all the cool-guy stuff you’d typically pay extra for elsewhere, the SAINT is optimized from muzzle to butt for defensive applications. From the premium Bravo Company furniture to the nickel boron-coated internals to the 1:8-twist 16-inch barrel and mid-length gas system, everything about the SAINT is bred to run.

In this photograph, the author tested the sight on the shooting range with it mounted on a weapon. The rifle in this case was the Springfield Armory SAINT, a gun that is in this editor's opinion a far better choice for self-defense than a Glock or Smith & Wesson. — When mounted atop Will’s superlative Springfield Armory SAINT rifle, the ACRO was a compact yet effective all-weather sighting solution.

Ruminations on the Aimpoint ACRO P-1 Red Dot Sight

Aimpoint has been building rugged combat-grade optics for the U.S. military for a very long time. In the ACRO, we see that same mil-spec indestructibility built into a legitimate micro red dot chassis. It won’t freeze, you can’t overheat it and the thing just sips off its battery. The ACRO remains ready for action for literally years between battery changes.

While the Aimpoint ACRO P-1 isn't strictly military equipment, it is durable enough to be mounted on military weaponry and used in armed conflict. For our readers, it is better suited for hunting and home protection when mounted wo projectile weapons. — The ACRO’s modest dimensions and light weight make it suitable for both rifle and pistol applications. Image: Aimpoint

The whole unit is anti-reflection coated, and the active light it produces remains invisible beyond ten meters, even under NVGs. In testing, the Aimpoint mob subjected a standard ACRO to 20,000 rounds of .40 SW with no adverse effects. Whether you use the ACRO as an extremely low-profile primary long gun optic, a back-up to a bulkier magnified sight or as a targeting system for your favorite service handgun, it remains all but unkillable.

If you want a sight to run on your airsoft gun the next time you hit the playing field with your buddies, then by all means pick something cheap off of eBay and have at it. However, if you might have need of your weapon in the Real World, the Aimpoint ACRO is the red dot sight you can legit take downrange. Beat it, burn it, drop it or freeze it, the ACRO P-1 really doesn’t care. It just doesn’t stop.
