Aimpoint Duty RDS vs Holosun HS510C

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

Two open red dots for Picatinny-rail rifles. Aimpoint’s Duty RDS has a single 2 MOA dot; Holosun’s HS510C adds a selectable multi-reticle and a solar backup. Figures come from each maker’s own product page, read on November 5, 2026. Aimpoint’s Duty RDS category page showed no specs, so we used its individual 2 MOA product page (item #200758, 30 mm mount).

Size and weight are quoted differently, so do not read them as exactly like-for-like. Aimpoint prints 80 × 41 × 58 mm and 140 g for the sight with its 30 mm mount; Holosun prints body figures. No prices are in this table. Holosun’s page showed $364.69 on November 5, but that is the price shown on Holosun’s page, not MSRP data, and Aimpoint’s page showed none.

What differs on paper

Runtime: Aimpoint prints 30,000 hours at setting 6; Holosun prints 50,000 hours at setting 6.
Reticle and power: the HS510C offers a selectable dot, circle or both, and Holosun lists solar power and automatic brightness. Aimpoint lists a single 2 MOA dot.
Brightness steps: Aimpoint lists six daylight and four night-vision settings; Holosun lists ten daylight and two.
Weight: the Aimpoint is 110 g (3.9 oz) as a sight only; Holosun prints 4.94 oz for the HS510C body.
Aimpoint also sells a 39 mm mount version (item #200759): its page prints 80 × 41 × 67 mm, 160 g with mount, and a 39 mm optical axis (“AR-15 Ready”).

Which to pick (on paper)

A plain 2 MOA dot from a long-established duty-optic maker: the Duty RDS. Aimpoint describes it as designed for law-enforcement use.
A selectable reticle, solar backup and a longer printed runtime: the HS510C.

We have not range-tested either, and no durability claim above is ours; every figure is quoted from the maker’s page.

Frequently asked questions

How long does the Aimpoint Duty RDS battery last compared with the Holosun HS510C?

Aimpoint prints 30,000 hours at daylight setting 6 for the Duty RDS, on one CR2032. Holosun prints 50,000 hours at setting 6 for the HS510C, also on a CR2032.

Does the Aimpoint Duty RDS have a selectable reticle?

Not the 2 MOA model compared here, which lists a single 2 MOA dot. Aimpoint's category page also lists a Duty RDS MR with a 2 MOA dot and 65 MOA circle, which we did not compare. The Holosun HS510C lists a selectable 2 MOA dot and 65 MOA circle.
