Description
The Holosun HS515CM is an enclosed micro red dot sight for rifles and carbines. It uses the red Multi-Reticle System, letting you select a 2 MOA dot, a 65 MOA circle or the circle-dot combination, and it runs on a side-loading CR2032 battery with Solar Failsafe backup for up to 50,000 hours on setting 6. The sight ships on a quick-detach Picatinny mount at lower 1/3 co-witness height (1.63 in) with rotating, removable lens caps, making it a drop-on optic for AR-pattern, straight-pull and lever-action rifles used in Australian service-rifle, 3-gun style and hunting applications.

FAQ
What is the difference between the HS515CM and the HS515GM? Both are 515-series enclosed micro sights. The HS515CM has side-mounted controls with the solar panel over the battery compartment; the HS515GM uses top-mounted buttons. Holosun also lists a green-reticle version of this sight as the HE515CM-GR.
Does the HS515CM need its battery removed to change it? No. The CR2032 sits in a side tray, so it can be swapped without removing the sight from the rifle or re-zeroing.
Is the mount included? Yes. The HS515CM comes fitted with a quick-detach Picatinny mount at lower 1/3 co-witness height (1.63 in) and includes protective lens caps.
