Trijicon RCR vs. Acro P2: A Comprehensive Comparison

The world of micro red dot sights has expanded rapidly in recent years, offering an increasing number of rugged, closed-emitter options for pistol shooters. Two contenders currently dominating conversations are the Trijicon RCR (Ruggedized Closed Reflex) and the Aimpoint Acro P2. Below, we break down the key features, strengths, and weaknesses of each optic to help you decide which best suits your needs.

What Sets These Optics Apart?

1. Overall Design & Footprint

• Trijicon RCR:

  • Closed Emitter Design: Unlike the open design of the RMR, the RCR is fully enclosed, offering additional protection against dirt, water, and debris.
  • Mounting Footprint: Trijicon engineered the RCR to use the same footprint as the widely-used RMR. This is a big plus if you’ve already got an RMR-cut slide or existing mount—no need to buy an entirely new setup.
  • Build Quality: In keeping with Trijicon’s reputation, the RCR is reportedly robust, with an aluminum housing designed to take a beating.

• Aimpoint Acro P2:

  • Closed Emitter Legacy: The Acro series from Aimpoint was one of the first truly successful enclosed micro red dots. The P2 model refines the original design, addressing battery life concerns and other minor issues.
  • Acro Footprint: The P2 uses Aimpoint’s proprietary Acro mounting system, meaning you’ll need a compatible plate or direct-milled slide.
  • Aimpoint Durability: Aimpoint has a storied history of producing optics that can survive extreme conditions. The Acro P2 is no exception.

2. Battery Life & Location

• RCR:
  While official hour counts are still emerging (Trijicon is known for conservative battery estimates), early reports suggest the RCR can stand toe-to-toe with other modern red dots on battery life. Expect thousands of hours on a single battery. The battery compartment is designed for simple swaps, though specifics can vary depending on final production specs.

• Acro P2:
  The P2 significantly improved battery life over the original Acro P1—Aimpoint claims up to 50,000 hours at moderate settings. Better yet, the side-loading battery compartment means you can replace the battery without removing the optic (and potentially losing zero).

3. Size & Weight

• RCR:
  The RCR aims to match the RMR’s low-profile approach. It’s generally lighter than many other enclosed red dots on the market, making it an appealing option for concealed carry and competitive shooting alike.

• Acro P2:
  The Acro P2 is a bit boxier and can weigh slightly more than the RCR. Some shooters don’t mind the extra heft because it often translates into proven durability and a robust housing that handles abuse exceptionally well.

4. Field of View & Glass Clarity

• Trijicon RCR:
  Field of view is reported to be adequate for most pistols, and Trijicon’s glass typically boasts excellent clarity and minimal tint. Early feedback suggests that the RCR retains the crisp glass quality that RMR users enjoy.

• Aimpoint Acro P2:
  Aimpoint optics are lauded for their sharp, high-quality lenses. The Acro P2’s slightly larger window can offer a forgiving viewing experience, though some users note that it can feel more “tunnel-like” due to the boxy shape.

5. Real-World Considerations & User Feedback

• Mounting Options:

  • RCR: If you already have an RMR-cut slide or prefer an RMR footprint, the RCR’s compatibility is a major plus.
  • Acro P2: Requires an Acro-specific plate or direct milling. The good news? Plates for the Acro are increasingly available, and many manufacturers now produce them.

• Concealability:

  • RCR: Tends to be slightly more low-profile, making it a potentially better match for everyday carry.
  • Acro P2: Slim enough to conceal but does protrude more than some open emitter sights.

• User Reviews:

  • Trijicon RCR: Owners who have tried it mention a seamless transition from their RMR. They appreciate the closed emitter for adverse weather or dusty conditions.
  • Acro P2: Seasoned Acro users love the updated battery life and report consistent zero retention. The fully enclosed design keeps the emitter lens crystal clear in dirty or wet environments.

6. Price & Availability

• RCR: As a newer product, pricing can fluctuate, but it’s often in the same range as premium optics—typically $600 to $700.
• Acro P2: Similar territory, usually around $600 to $700, though Aimpoint’s brand reputation sometimes commands slightly higher prices.

Which One Should You Choose?

Both the Trijicon RCR and the Aimpoint Acro P2 are solid choices if you’re looking for a robust, closed-emitter red dot sight. In many ways, the deciding factor boils down to a few questions:

1. Mounting Footprint: Do you already have an RMR-cut slide or do you have the flexibility to add an Acro plate?
2. Form Factor: Do you prefer the slightly slimmer profile of the RCR, or are you comfortable with the Acro P2’s shape and weight?
3. Brand Loyalty & Track Record: Trijicon and Aimpoint both have reputations for reliability, so it may come down to personal preference.

Ultimately, you can’t go wrong with either optic. The RCR is appealing to those who want a next-generation Trijicon product that’s more protective than an open emitter. Meanwhile, the Acro P2 continues Aimpoint’s tradition of building rugged sights that endure the harshest environments. Whichever you pick, you’ll be adding a top-notch, enclosed red dot to your defensive or competitive shooting setup.
