{"product_id":"holosun-he510c-green-dot-sight","title":"Holosun HE510C Green Dot Sight Multi-Reticle System Solar Failsafe","description":"\u003cp\u003eThe Holosun HE510C in green, part number HE510C-GR, is a 1x open reflex rifle sight with the Multi-Reticle System behind a 0.91 x 1.26 in (approximately 23 x 32 mm) window.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe reticle is switchable: a 2 MOA green dot on its own for a precise hold, a 65 MOA circle on its own for speed at close range, or both together, changed with a button rather than a menu.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe housing is aluminium with a titanium protective hood over the glass, finished in MAO black, rated IP67 and weighing 4.94 oz (140 g) at 3.3 x 1.68 x 1.78 in. Holosun supplies a quick-detach Picatinny mount that puts the optic at 1.41 in. Illumination has 12 settings, 10 for daylight and 2 for night vision, adjustment is 0.5 MOA per click across ±50 MOA, and a CR2032 is rated for up to 50,000 hours at setting 6 with Solar Failsafe and Shake Awake supporting it.\u003c\/p\u003e\n\u003cp\u003eThe wide rimless window is the reason the 510 pattern became a default on AR-pattern carbines and practical shotguns: it gives a genuinely heads-up picture with both eyes open. A green emitter is easier for most eyes to see in bright light than red, at the cost of drawing marginally more current at the same setting. This part number is supplied in the MAO black finish only.\u003c\/p\u003e\n\u003ch3\u003eWhy shooters choose the HE510C\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReticle\u003c\/strong\u003e — green Multi-Reticle System — 2 MOA dot, 65 MOA circle, or circle dot\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWindow\u003c\/strong\u003e — wide rimless open reflex window, 0.91 x 1.26 in\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\u003eIllumination\u003c\/strong\u003e — 12 settings — 10 daylight and 2 night vision compatible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustment\u003c\/strong\u003e — 0.5 MOA per click across ±50 MOA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuild\u003c\/strong\u003e — aluminium with a titanium hood, IP67, 4.94 oz (140 g)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat the HE510C fits\u003c\/h3\u003e\n\u003cp\u003eIt comes on a quick-detach Picatinny mount at 1.41 in optic height, so the rifle or shotgun needs a MIL-STD-1913 rail section to take it, with room behind if you intend to run a magnifier.
