Fully Enclosed Housing

Unlike many micro sights sporting an open optical design, the Acro P-1 is fully encased with lenses recessed deep within the housing. This provides enhanced protection from debris, damage, and fouling issues. I’ve found most open emitter dots will inevitably end up with dust, oil, or wetness obscuring the lens even with protective covers. No such issues with the Acro P-1 thanks to its sealed design.

Waterproof Rating 

With its robust sealing, it’s no surprise the Acro P-1 boasts an impressive IP68 rating. That means complete waterproofing and ability to continuously operate when submerged to 25 meters depth. To test it out, I left mine underwater for over an hour with no functioning degradation whatsoever. While I don’t plan on diving missions with my EDC pistol, it’s good peace of mind for shooting conditions!


Built into the base of the Acro P-1 is Aimpoint’s modular ACRO interface system. This allows attaching secondary accessories like optical magnifiers, anti-reflection devices, kill flash filters, and more. With users reporting 50,000+ hours of up time on a single battery, chances are you won’t be needing these add-ons often. But it’s nice having options to enhance functionality down the road.

Performance Analysis: Accuracy, Precision, and Versatility of the Aimpoint Acro P-1

When testing out a new firearm optic, my criteria focuses on three key factors: accuracy, precision, and versatility. The Acro P-1 delivers impressively on all fronts. Here’s why this micro powerhouse punches outside its weight class.


With the Acro P-1’s 3.5 MOA dot staying parallax free and the unlimited eye relief, transitioning between targets at varying distances proved a breeze. The dot tracks perfectly in line with the bore axis for increased hit probability.

In testing the Acro P-1 with various firearms, including those chambering Winchester and Smith & Wesson cartridges, I found that the sight maintained zero impeccably, even after 100 rounds. The robust build of the Acro P-1 effectively handles the muzzle recoil of diverse handguns, demonstrating its versatility across different chamberings.

Testing five 5-shot groups at 25 yards offhand, I was able to achieve consistent 1” clusters. Dialing it back to 10 yards, groups shrank down to jagged holes even piecing multiple rounds through previous bullet holes. For a micro pistol dot sight, I consider that exceptional accuracy.


One concern I had was whether the 3.5 MOA dot would provide sufficient precision for longer range shooting. The dot does obscure more of the target decreasing your finessed aim point.

However, testing out to 50 yards, I was still able to ring steel targets multiple times in a row. The sight picture and superimposed dot provide plenty of reference for getting rounds on target outside typical pistol engagement distances.


While designed primarily for handguns, user reports indicate the Acro P-1 functions well as a backup sight or supplementary optic. The lightweight and compact chassis allow mounting on rifles and shotguns without adding much bulk.

Likewise, running drills from concealment as well as rapid fire exercises proved the Acro P-1 can run speedily with the best of them. The sight acquires smoothly from the draw and transitions rapidly from target to target. The 10 daytime brightness settings also make it suitable for close quarters indoor use.

With impressive accuracy within 100 yards, unlimited eye relief, and ability to handle abuse on heavy recoiling platforms, the Acro P-1 makes a versatile cross-platform solution.

User Experience: Handling and Operating the Aimpoint Acro P-1

Getting an optic sighted in and properly mounted is critical for harnessing its full performance. Here’s my first-person walkthrough on getting the Acro P-1 up and running for flawless functionality.

Mounting Process 

The Acro P-1 uses a cross-bolt mounting system centering on its integrated ACRO interface footprint. This allows solid, indexable mating with interface adaptor plates or direct milling options.

For my FN 509 Tactical OS, I chose the CHPWS plate which aligned precisely with the ACRO cross-bolt channels. Slight tightening pressure seats the sight firmly without any wiggle. Yet it still releases easily for battery swaps without full remounting.

Zeroing Procedure 

Like most quality dots, the Acro P-1 uses click adjustable turrets for windage and elevation. The adjustments use a Torx T10 driver to dial in point of impact.

Starting at 25 yards, I first centered the dot on target and fired a 5-shot group. Seeing the grouping bias slightly left and low, I then dialed in 4 clicks right and 3 clicks up as initial correction. After confirming adjustments, I then fine tuned with 1-2 click tweaks until obtaining center point of impact.

The adjustment range of 30 MOA (85 cm at 100 meters) provides a sufficient zeroing zone for most handgun or backup use. One tip I’ve found useful is using a sharpie to mark witness dots on the sight as reference points after getting it perfectly zeroed in.

Daily Use 

With the Acro P-1 accounting for weight, balance, and sight radius of the host pistol, it transitions seamlessly once zeroed. I found very minimal point of impact shift even after 500+ rounds. And swapping it between my Glock 17 and FN 509 only requires very minor tweak corrections to re-center impact point.

Operation is intuitive with ambidextrous brightness buttons quickly accessible. The buttons also allow for rapid powering on-off helping conserve battery life. One enhancement I’d suggest is adding momentary pressure activation rather than relying solely on lock-in settings.

The sight picture presents the dot clearly without occlusion or distortion even at max brightness. And the 10 daytime settings provide a good range from basement low light use up to full sun at the range.

Maintenance Tips 

As a rule with all my RDS optics, I make it habit to reconfirm zero every range trip regardless of round count. It takes seconds to validate point of impact but saves hassle down the road if you ever suffer an inadvertent bump that shifts your system.

Some users report issues with foreign matter ingress after repeated firing , so I also check battery cap sealing prior to exposure to ensure no debris or moisture ingress occur. The manual advises lens cleaning by blowing away debris versus wiping to prevent scratching. But I often use lens wipes and cotton swabs applying gentle pressure for stuck-on particles. No degradation so far but wipe carefully all the same!

Mounting Solutions and Compatibility for the Aimpoint Acro P-1

Mounting any accessory securely is vital for optimal performance. And given its cutting-edge design, the Acro P-1 requires fitting components that properly interface with its cross-bolt platform. Here’s some mounting solutions I recommend from personal testing:


For Glocks, CZ, Sig Sauer, and Springfield Armory handguns, the CHPWS ACRO mounting plates provide secure mating with low profile interface. Plates fit popular models like Glock 17, 19, 43X, 48, Sig P320 XFive, CZ P10F OR, and Springfield XDM Elite 3.8.

While designed for pistols, the lightweight Acro P-1 works effectively on lightweight carbines and SBRs. For AR15 use, the Reptilia Dot Mount attaches directly to picatinny rails while enabling absolute or 1/3 co-witness with iron sights.


The Musso Mount is my go-to for interfacing the Acro P-1 with picatinny-equipped shotguns like Remington 870s, Mossberg 500 series, and Benelli M2/M4. Bridge mount options also available for Weaver and MIL-STD 1913 rails.

Installation Best Practices 

As receiver dimensions and configurations vary across firearm platforms, always double check precise interface measurements against manufacturer specs for proper alignment.

Use thread-locker like Loctite on mounting screws to prevent loosening over sustained shooting sessions. Over-tightening can cause damage so find the sweet spot with just enough torque to securely seat the sight and maintain point of aim.

Ensure your sighted zero before entering field use by confirming bullet impact on paper after installation along with routine pre-range validation. This saves headaches of finding shotgun patterns or handgun rounds impacting way off due to a shifted optic!

Maintaining the Aimpoint Acro P-1: Longevity, Battery Life, and Care

An optic that fails due to lack of maintenance negates all its performance capabilities. Based on my testing regiment, here are some tips for keeping your Acro P-1 running for the long haul:

Preventative Maintenance 

While sealed optics like the Acro P-1 reduce environmental exposure, install protective covers when not in use to prevent nicking or scratching. I prefer flip covers which quick-attach when needed versus caps that are prone to getting knocked off or lost.

Periodically inspect the battery compartment seal with a visual check and function test by immersing in water to ensure proper waterproofing remains intact over years of use.

Optimizing Power Efficiency 

To get max battery lifespan, utilize mid-range brightness settings tailored to current lighting conditions instead of leaving it dialed up full blast. I keep mine at setting 6 for all but the dimmest indoor scenarios.

Carry spare batteries on longer excursions. While rated for exceptional battery life exceeding a year, voltage can deplete unexpectedly in cold weather. Lithium batteries handle temperature swings better than alkaline options anyway.

Lens Maintenance 

I’m pretty religious about lens care to prevent degraded optics or permanent fouling/fogging. Soft microfiber cloths are perfect for wiping away dust or debris on lenses versus using shirt tails or other fabrics that could scratch.

For more stubborn oil or dirt that won’t blow clear, apply a drop of non-ammonia lens cleaner like ClearArmor directly to the cloth versus spraying. Then gently wipe residue away using a circular motion rather than dragging across the surface.

Comparative Review: Aimpoint Acro P-1 vs. Industry Competitors

While the Acro P-1 has stirred up lots of chatter in gun circles, there are definitely quality alternatives that give it a run at the top. Here’s how I feel the Acro P-1 stacks up to two other favorites of mine.

Aimpoint Acro P-1 VS Trijicon RMR 

Like the Acro P-1, Trijicon’s RMR line set the performance benchmark that many micro red dots still strive to match. The current RMRcc edges closer to the Aimpoint’s compact form factor at 1.2 ounces lighter. However, I prefer the Acro P-1’s battery life exceeding 4 years over the RMRcc’s rated 5 years shelf life.

The RMR shines in the precision realm with adjustability down to a 1 MOA dot. But despite its finer aim point I still had difficulty besting my groupings with the Acro P-1. Plus you’ll pay $200+ more for the smaller RMR dots versus the Acro’s bang-on 3.5 MOA.

Aimpoint Acro P-1 Holosun 507c 

As a budget-priced alternative, the Holosun 507c packs a lot of capability into its diminutive open-emitter design. It holds its own with 32 MOA ring and 2 MOA dot options, solar failsafe power augmentation, and multi-reticle switching.

However battery access requires sight removal and shorter run times between changes make the Acro P-1 better suited for extended use. The Aimpoint’s reputation for battle-tested ruggedness also overshadows Holosun’s reliability claims in torturous conditions.

For my money, the closer competition from tested industry larges still can’t match the Acro P-1’s unique balance of size, battery life, no-fail durability, and enhanced optics integration.

Aimpoint Acro P-1: Personalized Use Cases and Recommendations

With any personal gear decision, your intended uses determine which product optimally fits the bill. Based on my range of needs, here’s how the Acro P-1 earns a regular spot in my rotation:

Home Defense Pistol 

For bump-in-the-night preparedness, a lightweight red dot sight on my bedside handgun makes target acquisition effortless compared to typical night sights. And the Acro P-1’s durability gives me confidence it won’t get knocked out of zero if accidentally bumped in the safe.

The easy user interface and unlimited eye relief make bringing the gun on target rapidly a cinch, even when fatigued. The Acro P-1 quickly became my go-to choice to enhance my Glock 19’s defensive capabilities.

Hunting Sidearm 

While some debate optics on hunting sidearms, I’ve found them invaluable for accurate shot placement when following up wounded game. And the Acro P-1 provides the perfect balance of precision aiming without weighing down my pack on long treks. Now follow up shots rarely require more than one bullet.

Competition/Action Pistol 

Here the Acro P-1 again checks boxes being easy to run hard with fast sight acquisition and lag-free transitions. Without fail, the Acro P-1 runs every time I smash the power button just as furiously as I tap the trigger. Its rugged design withstands abuse that would sideline cheaper optics. My hit percentages and stage times confirm why so many pro competitors gravitate toward this mini tank.
