Holosun HE515GT-RD Black 1x20mm 2 MOA Red Dot/65 MOA Red Circle Multi Reticle Sight
Holosun
The Holosun SCRS RD MRS is a compact 1x20mm red dot sight built for shooters who want a rugged, versatile optic that adapts to any light condition without draining batteries. Solar charging technology backed by manual intensity control means you're never stuck with a dim dot in low light or a washed-out reticle in bright sun. The multi-directional light sensors automatically dial in the right brightness, or you can take the wheel yourself—that flexibility matters when you're hunting in changing conditions or running drills at the range.
Built from 7075 aluminum and finished in hard black anodize, the SCRS is made to take punishment. At just 20mm across, it's compact enough to coexist with magnified optics as a backup sight or primary on a lightweight build. The 509T footprint means it plays nice with third-party offset mounts, giving you placement options without locking you into Holosun-only accessories.
The Multi-Reticle System gives you flexibility in the field: a 2 MOA red dot for precision aiming at distance, paired with a 65 MOA red circle for rapid target acquisition and quick follow-ups. Switch between them depending on your shot—tight dot for standing, precision hits; big circle when speed counts. That's one sight handling multiple roles without compromise.
Whether you're building a rifle for hunting, competition, or duty-grade reliability, the SCRS RD MRS delivers the practical simplicity of a red dot with the tactical options serious shooters expect.
