Centre height from ring to base is \u003cstrong\u003e50 mm\u003c\/strong\u003e, compatible with objectives up to \u003cstrong\u003e65 mm\u003c\/strong\u003e in diameter and suitable for use with cheek risers or height-adjustable stocks.\u003c\/p\u003e\u003cp\u003eAt \u003cstrong\u003e156 mm\u003c\/strong\u003e in length, the cantilever moves the optic far enough forward to provide comfortable eye relief even with short scopes or shooting glasses, without having to adjust the shoulder position. The mount attaches to the rail via \u003cstrong\u003e2 cross bolts\u003c\/strong\u003e, while each ring is secured by \u003cstrong\u003e4 screws\u003c\/strong\u003e: the distributed clamping load reduces the risk of tube deformation even under sustained recoil. The trade-off to consider is weight: \u003cstrong\u003e163 g\u003c\/strong\u003e for a CNC-machined 6063-T6 aluminium one-piece is on par with the category average, but those prioritising minimum weight may want to compare it with separate two-piece mounts, which however require precise alignment of both rings during installation.\u003c\/p\u003e\u003cp\u003eThe declared cant is \u003cstrong\u003e0 MOA\u003c\/strong\u003e: the mount introduces no vertical angular correction, making it trajectory-neutral and suitable for variable-distance shooting where all correction is handled by the optic itself. The matte black finish reduces glare in direct light conditions.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThe cantilever profile moves the optic forward, allowing a natural position on the sight line without altering the cheek weld or shoulder position.\u003c\/li\u003e\n\u003cli\u003eThe \u003cstrong\u003e50 mm\u003c\/strong\u003e height accommodates objectives up to \u003cstrong\u003e65 mm\u003c\/strong\u003e without interference from the rail or receiver.\u003c\/li\u003e\n\u003cli\u003eThe CNC-machined one-piece 6063-T6 aluminium body eliminates any relative play between the two rings, which can develop in separate two-piece mounts after repeated removal and reinstallation.\u003c\/li\u003e\n\u003cli\u003eThe \u003cstrong\u003e0 MOA\u003c\/strong\u003e cant leaves aiming geometry unchanged: no pre-set correction to compensate for during zeroing.\u003c\/li\u003e\n\u003cli\u003eThe 4-screw clamping per ring distributes pressure evenly around the tube, reducing the risk of marks or deformation even under high-recoil calibres.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eIn the box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003eVector Optics one-piece cantilever mount 25.4 mm RIS, 50 mm height\u003c\/li\u003e\u003c\/ul\u003e","brand":"Vector Optics","offers":[{"title":"Default Title","offer_id":63798858580298,"sku":"SCTM-66","price":40.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0026\/3920\/0291\/files\/85455.jpg?v=1791147594","url":"https:\/\/www.vipertactical.it\/en\/products\/vector-optics-25-4-mm-ris-cantilever-mount-black","provider":"Viper Tactical ","version":"1.0","type":"link"}
