Aimpoint Acro C-2 vs Acro P-2

By Cole Harlan, EditorUpdated Nov 5, 2026How we verifyEditorial standards

On paper the two share size, weight, dot size and battery life. The biggest cited difference is water depth: Aimpoint lists the Acro C-2 as submersible to 5 meters (15 feet) and the Acro P-2 to 35 meters (115 feet), plus a different night-vision/daylight setting split (2 + 8 vs 4 + 6). Figures are copied from Aimpoint’s product pages, checked November 5, 2026.

Like for like: the rows use the same labels on both Aimpoint pages, so they pair directly. The differences are all in the water depth, the night-vision/daylight setting split and the transmission band and percentage. Weight is sight only on both. We read no MSRP on either page and show none; we make no claim about which sight suits which user beyond what the pages print.

Which to pick (on paper)

If listed water depth matters: the Acro P-2 at 35 meters (115 feet) against the Acro C-2’s 5 meters (15 feet).
If more night-vision-compatible settings matter: the Acro P-2 lists 4 (with 6 daylight); the Acro C-2 lists 2 (with 8 daylight).
If more daylight settings matter: the Acro C-2 lists 8; the Acro P-2 lists 6.
If listed transmission matters: the Acro P-2 lists an average 70% over 420 - 900 nm; the Acro C-2 lists an average 60% over 420 - 700 nm.
If size, weight, dot size or battery life decide it: Aimpoint lists the same values for both, so they do not separate the two on paper.

We have not range-tested these; facts above are from the makers.
