The circle pulls the eye back to centre for speed, the chevron tip gives a finer hold than a round dot, and Shake Awake with last-setting recall keeps the sight ready without draining the cell.

On the Holosun HS507K X2 ACSS the circle pulls the eye to centre for fast reacquisition, while the tip of the chevron gives a more precise hold than a round dot.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eIs the Holosun HS507K X2 ACSS an RMR or an RMSc footprint optic?\u003c\/b\u003e\u003cbr\u003eThe Holosun HS507K X2 ACSS uses the Holosun K footprint, which is the RMSc pattern, so it fits RMSc-cut slides and RMSc-pattern adapter plates. It is not an RMR-footprint optic; the RMR version of this reticle is the HS507C X2 ACSS.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eWill the Holosun HS507K X2 ACSS fit a SIG P365 or a Glock 43X?\u003c\/b\u003e\u003cbr\u003eBoth of those pistols use the RMSc optic cut, which matches the Holosun K footprint on the HS507K X2 ACSS, so the sight fits that cut directly. Confirm your slide is the optics-ready RMSc variant before ordering.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eDoes the Holosun HS507K X2 ACSS have solar power?\u003c\/b\u003e\u003cbr\u003eNo. The Holosun HS507K X2 ACSS runs from a CR1632 cell alone. Shake Awake with last-setting recall is what supports the 50,000-hour runtime rating on the K-series; Solar Failsafe is fitted to the larger C-series models.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eHow much does the Holosun HS507K X2 ACSS weigh?\u003c\/b\u003e\u003cbr\u003eThe Holosun HS507K X2 ACSS weighs 1.0 oz (28 g) and measures 1.6 × 0.98 × 0.95 in (40.6 × 24.9 × 24.1 mm), which is what allows it to sit on a slimline slide without unbalancing the pistol.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eHow tough is the Holosun HS507K X2 ACSS?\u003c\/b\u003e\u003cbr\u003eThe Holosun HS507K X2 ACSS has an aluminium housing rated IP67 for water and dust and tested to 5000G of vibration, so slide reciprocation and British weather are both within its rating.\u003c\/p\u003e","brand":"Holosun","offers":[{"title":"Default Title","offer_id":58434901082456,"sku":"HS507K-X2-ACSS","price":399.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0995\/2005\/3592\/files\/holosun-hs507k-x2-red-dot-sight-acss-vulcan-reticle-hs507k-x2-acss-1.jpg?v=1789007602","url":"https:\/\/opticstrader.co.uk\/products\/holosun-hs507k-x2-red-dot-sight-acss-vulcan-reticle-hs507k-x2-acss","provider":"Optics Trader","version":"1.0","type":"link"}
