Aimpoint Acro
The Aimpoint Acro P-2 represents a significant evolution in red dot optic design — a fully enclosed emitter in a compact housing that delivers Aimpoint’s legendary 50,000-hour battery life alongside the debris and weather resistance of a sealed system. Where open-emitter optics (RMR, Holosun 507C) expose the LED to the elements, the Acro’s enclosed design eliminates the most common optic failure point for duty and field use. Combined with the Acro footprint becoming a widely adopted mounting standard, the P-2 has become one of the most important pistol and compact rifle optics released in recent years.

Acro P-2 vs. Acro P-1: What Changed?
The Acro P-2 is the current generation, replacing the original P-1 with a 6x improvement in battery life — from approximately 1.5 years (P-1) to 50,000 hours (roughly 5.7 years) on a single CR2032 battery. The P-2 also features a larger, more defined adjustment turret and refined housing tolerances. The P-1 was criticized for its relatively short battery life compared to competing optics; the P-2 directly addresses that with Aimpoint’s standard 50,000-hour rating. Current production Acros are all P-2s. If you find a P-1 on the used market, the battery life disadvantage is significant enough that the P-2 is worth the difference in cost for any duty or carry application.
Acro C-2: The Compact Rifle Version
The Aimpoint Acro C-2 is the carbine/rifle variant of the Acro platform, featuring the same enclosed emitter design in a housing optimized for standard Picatinny rail mounting on rifles and carbines. The C-2 is lower-profile than the Micro T-2 and uses the same 50,000-hour battery. For shooters who want a single optic that can move between a pistol (with the Acro footprint) and a rifle (on Picatinny), the Acro platform offers that flexibility with different mounts. The C-2 is popular for suppressed rifle builds where the low-profile housing doesn’t interfere with suppressor handling.
Aimpoint Acro Footprint: Pistol Compatibility
The Acro P-2 uses the Aimpoint Acro footprint, which has been adopted by a growing number of pistol manufacturers as a factory optic-cut option. Pistols with direct Acro-cut compatibility include the Sig Sauer P320 X-series, Beretta 92X Performance, CZ Shadow 2 OR, and select Glock MOS configurations with an adapter plate. The Acro footprint is distinct from the Shield RMSc footprint used by Holosun’s 507C and 507K — they are not interchangeable without adapter plates. Always confirm your pistol’s specific cut before purchasing. See also: Aimpoint Optics.
Why Choose the Acro Over an Open-Emitter Optic?
The primary argument for the Acro over open-emitter optics like the Trijicon RMR or Holosun 507C is environmental protection. In rain, dust, mud, or any situation where debris could land on the emitter, the Acro’s sealed housing maintains full function. For law enforcement duty use, military applications, or hunting where the pistol may be exposed to weather, the enclosed design provides meaningful real-world reliability. The Acro’s 50,000-hour battery life also exceeds the RMR Type 2’s approximately 4-year rating. The tradeoff is a larger footprint than the RMR and limited holster compatibility compared to the more widely supported RMR standard.
Holster Compatibility With the Aimpoint Acro
Holster support for the Aimpoint Acro has grown significantly since the P-2’s release. Safariland produces ALS and SLS duty holsters with Acro-specific optic cuts for popular service pistols, and Tier 1 Concealed, Tenicor, and Dark Star Gear offer concealment holsters for common Acro-equipped pistols. However, holster availability for the Acro remains more limited than for the RMR or Shield RMSc footprint — verify holster availability for your specific pistol-and-optic combination before purchasing. This is particularly relevant for concealed carry configurations where holster fit is critical.
