{"product_id":"holosun-hs510c-fde-green-dot-sight","title":"Holosun HS510C Green Dot Sight Multi-Reticle System Solar Failsafe FDE","description":"\u003cp\u003eThe Holosun HS510C in Flat Dark Earth is a 1x open reflex sight with a green Multi-Reticle System — a 2 MOA dot, a 65 MOA circle or both — behind a 0.91 × 1.26 in window, on an integrated quick-detach Picatinny mount.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe rimless window is the reason this sight sells: there is no tube edge to look past, so the shooter keeps both eyes open and the 65 MOA circle drops onto a close target almost without conscious aiming.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA titanium hood shields the emitter over an aluminium body finished in Flat Dark Earth by MAO, rated IP67, tested to 1000G and usable from −30 °C to 60 °C. It measures 3.30 × 1.68 × 1.78 in and weighs 4.94 oz. The 540 nm green LED runs 12 brightness settings — 10 daylight and 2 for night vision — in manual or automatic mode with a lockout, adjusting 0.5 MOA per click across ±50 MOA, and the side-loading CR2032 gives up to 50,000 hours at setting 6 with Solar Failsafe and Shake Awake behind it.\u003c\/p\u003e\n\u003cp\u003ePractical shotgun, 3-Gun and carbine shooters buy it for the circle and the quick-detach mount; the green reticle holds up well against dark ground at dusk. Be clear that the emitter is open rather than enclosed, so heavy rain or mud on the front glass will affect the reticle in a way a sealed sight would not, and it needs a Picatinny rail section rather than a bare receiver.\u003c\/p\u003e\n\u003ch3\u003eWhy shooters choose the HS510C\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 — 0.91 × 1.26 in, rimless, with a titanium protective hood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIllumination\u003c\/strong\u003e — 12 settings — 10 daylight and 2 for night vision, manual or automatic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower\u003c\/strong\u003e — side-loading CR2032 with Solar Failsafe and Shake Awake, up to 50,000 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount\u003c\/strong\u003e — integrated quick-detach Picatinny mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing\u003c\/strong\u003e — aluminium with MAO Flat Dark Earth finish, IP67, 1000G\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat the HS510C fits\u003c\/h3\u003e\n\u003cp\u003eThe integrated mount clamps to any Picatinny rail, which on a shotgun means a rail section on the receiver or rib.
