It runs from a CR2032 rated up to 50,000 hours at setting 6, backed by Solar Failsafe and Shake Awake, in an aluminium housing with a titanium hood, MAO black finish and an IP67 rating at 4.94 oz. The HM3X is a 3x magnifier with 2.75 in of eye relief on a flip-to-side mount.\u003c\/p\u003e\n\u003cp\u003eBuying the pair together is cheaper than buying the two items separately, and the heights are already matched so the magnified image lines up with the sight. The thing to check before ordering is rail length: the receiver needs enough continuous MIL-STD-1913 rail to take the sight with the magnifier sitting behind it, which shorter uppers and some shotgun ribs will not give you.\u003c\/p\u003e\n\u003ch3\u003eWhy shooters choose the HS510C and HM3X combo\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSight\u003c\/strong\u003e — HS510C open reflex red dot with a wide rimless window\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReticle\u003c\/strong\u003e — red Multi-Reticle System — 2 MOA dot, 65 MOA circle, or circle dot\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnifier\u003c\/strong\u003e — HM3X at 3x with 2.75 in eye relief on a flip-to-side quick-detach mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower\u003c\/strong\u003e — CR2032 with Solar Failsafe and Shake Awake, up to 50,000 hours at setting 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustment\u003c\/strong\u003e — 0.5 MOA per click over ±50 MOA, 12 brightness settings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuild\u003c\/strong\u003e — aluminium with a titanium hood, IP67, 4.94 oz for the sight\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat the HS510C and HM3X combo fits\u003c\/h3\u003e\n\u003cp\u003eBoth units clamp to a standard MIL-STD-1913 Picatinny rail, one in front of the other, which suits an AR-pattern flat-top or a rail-topped straight-pull.
