Top 4 Best Red Dot Sights For AR-9 in 2024

Aimpoint PRO Patrol

⁠

⁠

I recently mounted an Aimpoint PRO Patrol red dot sight on my AR-15, and let me tell you, it's been a game-changer. This thing is built like a tank and delivers the kind of performance you need in any situation.

Specs and Features:

2 MOA red dot: Perfect size for fast target acquisition at close to medium range.

Mil-Spec hard anodized aluminum housing: Nearly indestructible, ready for bumps, drops, and whatever else you throw at it.

Waterproof down to 150 feet: No worries about rain, mud, or even taking a tumble in the water (not that I recommend it).

ACET technology: Boasts over 3 years of constant-on battery life on setting 7, even longer on night vision settings. That's serious peace of mind.

QRP2 mount: Makes attaching and detaching the sight a breeze, no tools required.

Best Features in Action:

The Aimpoint PRO excels in a few key areas:

Speed: The red dot makes acquiring targets insanely fast, especially compared to iron sights.

Durability: This sight is a beast. I've taken it on several range trips and some rough terrain, and it holds zero perfectly.

Night vision compatibility: A huge plus for low-light situations.

Both-eyes-open shooting: Keeps you situationally aware while maintaining a clear sight picture.

Downsides to Consider:

Price: Aimpoint sights are an investment, but the quality and reliability justify the cost in my opinion.

Weight: It adds a littleheft to your rifle compared to a bare iron sight setup.

Limited magnification: Not ideal for long-range shooting (although you can add a magnifier).

My Experience:

Since mounting the Aimpoint PRO, my accuracy and speed at the range have noticeably improved. The red dot is crisp and easy to see, even in bright sunlight. The overall build quality feels rock-solid, and the battery life is fantastic. It gives me the confidence to know my optic won't let me down when it matters most.

What Others Are Saying:

Online reviews for the Aimpoint PRO Patrol are overwhelmingly positive. Owners praise its durability, clarity, and ease of use. A common theme is that it's a worthwhile investment for anyone who wants a reliable red dot sight for their AR-15.

Overall, the Aimpoint PRO Patrol is a top-shelf red dot sight. It's a bit pricey, but for the performance and build quality you get, it's definitely worth the money. If you're looking for a red dot that will give you an edge at the range or in the field, the Aimpoint PRO Patrol is an excellent choice.

Size and weight: Compared to some micro red dots, the MRO is a bit bulkier. However, for a pistol, the size is still very manageable.

My experience:

Customer Chatter:

Online forums are buzzing with positive feedback about the Trijicon MRO. Users praise its durability, clarity, and ease of use. Some folks might recommend a micro red dot for weight savings on a pistol build, but overall, the MRO seems to be a favorite for those who prioritize ruggedness and performance.
