Brightness covers 10 daylight and 2 night-vision settings in manual or automatic mode, and the turrets move 0.5 MOA per click across ±50 MOA. Power is a side-loading CR2032 rated up to 50,000 hours, with Solar Failsafe as backup and Shake Awake to shut the reticle down when the rifle is still.\u003c\/p\u003e\n\u003cp\u003eThe sight weighs 4.94 oz, measures 3.3 x 1.68 x 1.78 in, and its aluminium housing carries a titanium hood over the emitter with an IP67 rating. It fits a Picatinny rail on a quick-detach mount, and the HM3X flips aside for a clean 1x picture. Two things to be straight about: this is an open reflex, so the emitter faces the weather in a way an enclosed sight does not, and Holosun does not publish a mount height for this kit, so check the co-witness against your own irons rather than assuming it.\u003c\/p\u003e\n\u003ch3\u003eWhy shooters choose the HE510C-GR combo\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSight\u003c\/strong\u003e — HE510C-GR open reflex with a 0.91 x 1.26 in window\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReticle\u003c\/strong\u003e — Multi-Reticle System — 2 MOA green dot and 65 MOA circle, selectable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnifier\u003c\/strong\u003e — HM3X 3x on a flip-to-side mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower\u003c\/strong\u003e — side-loading CR2032 with Solar Failsafe, up to 50,000 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIllumination\u003c\/strong\u003e — 10 daylight and 2 night-vision settings, manual or automatic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing\u003c\/strong\u003e — aluminium with a titanium hood, IP67 rated, 4.94 oz\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat the HE510C-GR combo fits\u003c\/h3\u003e\n\u003cp\u003eBoth parts clamp to a MIL-STD-1913 Picatinny rail, so an AR-pattern flat-top with enough rail length for sight and magnifier is the natural host.
