Holosun SCS Carry vs EPS: Solar Dot or Battery Dot

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

Two enclosed-housing Holosun pistol dots that both list a K footprint. The SCS Carry is a solar-charging sight with a built-in rechargeable battery and a multi-reticle; the EPS is a plain 2 MOA dot on a replaceable CR1620. We compare the SKU Holosun lists on each page: SCS-CARRY-GR (a green reticle) and EPS-RD-2 (a red 2 MOA dot). Because the colors differ, read the wavelength row as part of the comparison. Every figure is from Holosun’s product pages, checked November 5, 2026.

Holosun’s SCS Carry page describes an “Enclosed Emitter Design” with an integrated solar panel; the EPS page describes an enclosed emitter housing too. The SCS Carry we used is the green SKU; the page we fetched does not list a red SCS-CARRY option, so we did not assume one. Holosun lists the SCS Carry battery as non-removable, so battery life is a different question from the EPS’s swap-a-coin-cell design. We list no price: Holosun prints one on each page, but street prices move.

Which to pick (on paper)

If you do not want to buy batteries: the SCS Carry. Holosun lists a solar panel and an internal rechargeable battery, with 20,000 hours of reserve and operation “indefinitely with regular light exposure.” The EPS uses a CR1620 you replace from the side tray.
If you want a plain dot and manual brightness with memory: the EPS. Holosun lists a 2 MOA Dot, eight daylight and four night-vision settings and last-setting memory; the SCS Carry lists automatic brightness and no manual brightness.
If body size and weight on a slim gun matter: the SCS Carry. Holosun lists 1.06 oz and a 1″ by 0.95″ body width and height against 1.4 oz and 1.19″ by 0.99″. The windows list the same 0.9″ by 0.63″.
If you want a long swap-the-battery runtime: the EPS lists 50,000 hours at setting 6; the SCS Carry lists 20,000 hours of reserve.

We have not range-tested these; facts above are from Holosun’s pages. Not verified for either: price at retail and compatibility with your exact slide cut.
