The 65 MOA circle is the fast option for close shotgun and carbine work, and the 2 MOA dot is the precise one.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eIs the Holosun HS510C suitable for a shotgun?\u003c\/b\u003e\u003cbr\u003eYes. The Holosun HS510C has an integrated quick-detach Picatinny mount, an open window that keeps both eyes working, and a 65 MOA circle that suits fast target pick-up, which is why the HS510C family is a common choice for practical shotgun in the UK. It needs a Picatinny rail section on the receiver or rib.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eHow long does the battery last on the Holosun HS510C?\u003c\/b\u003e\u003cbr\u003eThe Holosun HS510C runs up to 50,000 hours on a single CR2032 at brightness setting 6. Solar Failsafe adds supplemental power in daylight and will keep the sight running if the cell fails, and Shake Awake shuts the reticle off when the gun is still.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eWill the Holosun HS510C co-witness with AR-pattern iron sights?\u003c\/b\u003e\u003cbr\u003eYes. The integrated quick-detach mount on the Holosun HS510C sets the dot at 1.41 in (35.8 mm), Holosun's stated co-witness dot height, so AR-height iron sights line up in the window on a standard flat-top receiver.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eIs the Holosun HS510C night-vision compatible?\u003c\/b\u003e\u003cbr\u003eYes. Two of the twelve brightness settings on the Holosun HS510C are night-vision compatible, so the reticle can be dimmed far enough to use behind a night vision device.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eCan I change the battery on the Holosun HS510C without losing zero?\u003c\/b\u003e\u003cbr\u003eYes. The Holosun HS510C uses a side-loading CR2032 tray, so the cell can be replaced with the optic still mounted and zeroed.\u003c\/p\u003e","brand":"Holosun","offers":[{"title":"Default Title","offer_id":58434907504984,"sku":"HS510C","price":349.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0995\/2005\/3592\/files\/holosun-hs510c-red-dot-sight-1.jpg?v=1789007710","url":"https:\/\/opticstrader.co.uk\/products\/holosun-hs510c-red-dot-sight","provider":"Optics Trader","version":"1.0","type":"link"}
