The large rimless window gives a genuinely heads-up, both-eyes-open sight picture, and many shooters find a green emitter easier to pick up in bright daylight than red. Solar Failsafe powers the dot from available light and keeps it lit if the CR2032 dies, Shake Awake sleeps the optic when it is still, and adjustment is 0.5 MOA per click with ±50 MOA of travel. The housing is rated IP67.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eHow It Compares\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eThe red version is the \u003ca href=\"\/products\/holosun-hs510c-red-dot-sight\"\u003eHS510C red dot sight\u003c\/a\u003e, also available in \u003ca href=\"\/products\/holosun-hs510c-fde-red-dot-sight\"\u003eHS510C red in Flat Dark Earth\u003c\/a\u003e and \u003ca href=\"\/products\/holosun-hs510c-fde-green-dot-sight\"\u003eHS510C green in Flat Dark Earth\u003c\/a\u003e.

The 65 MOA circle is the fast reference at close range and the 2 MOA dot is the precise one.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eWhy choose the green HE510C over the red HS510C?\u003c\/b\u003e\u003cbr\u003eMany shooters find a green emitter easier to pick up in bright daylight, because the eye is more sensitive to green than to red at the same output. The trade is that a green LED draws marginally more current than a red one at the same setting.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eWhat do Solar Failsafe and Shake Awake do on the HE510C?\u003c\/b\u003e\u003cbr\u003eSolar Failsafe powers the reticle from available light and keeps it lit if the CR2032 fails. Shake Awake switches the reticle off when the Holosun HE510C has been still and restores it instantly on movement, which together support the 50,000-hour runtime rating.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eIs the Holosun HE510C suitable for a shotgun?\u003c\/b\u003e\u003cbr\u003eThe Holosun HE510C is an open reflex sight with a wide window and a 65 MOA circle that suits fast target pick-up, which is why the 510C family is a common choice for practical shotgun in the UK. It needs a Picatinny rail section on the receiver or rib to mount to.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eCan I use a magnifier behind the Holosun HE510C?\u003c\/b\u003e\u003cbr\u003eYes. A flip-to-side magnifier such as the Holosun HM3X or HM6X mounts on the rail behind the Holosun HE510C, giving magnified target identification that swings aside for close work at 1x.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eIs the Holosun HE510C night-vision compatible?\u003c\/b\u003e\u003cbr\u003eYes. Two of the twelve brightness settings on the Holosun HE510C are night-vision compatible, so the green reticle can be dimmed far enough to use behind a night vision device.\u003c\/p\u003e","brand":"Holosun","offers":[{"title":"Default Title","offer_id":58434907603288,"sku":"HE510C-GR","price":369.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0995\/2005\/3592\/files\/holosun-he510c-green-dot-sight-1.jpg?v=1789007713","url":"https:\/\/opticstrader.co.uk\/products\/holosun-he510c-green-dot-sight","provider":"Optics Trader","version":"1.0","type":"link"}
