Holosun 509T QR Lower 1\/3 Mount is a quick-release mount engineered specifically for the Holosun 509T enclosed reflex sight. It positions the optic at lower 1\/3 co-witness height, allowing shooters to use backup iron sights through the lower third of the optic window while maintaining a natural cheek weld on AR-15 platforms. The patented QR Auto-Lock lever system provides tool-free attachment and removal with consistent return to zero.\u003c\/p\u003e\u003cp\u003eMachined from 6061-T6 aluminum with a hard-anodized finish, this mount is built for durability and repeated use. The lower 1\/3 height works well for shooters who prefer a slightly elevated optic position without completely obscuring iron sights. Compatible with any Picatinny or MIL-STD-1913 rail system.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Quick-Release Optic Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Optic:\u003c\/strong\u003e Holosun 509T\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e Lower 1\/3 Co-Witness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 6061-T6 Aluminum, Hard Anodized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment:\u003c\/strong\u003e QR Auto-Lock Lever (Tool-Free)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRail Compatibility:\u003c\/strong\u003e Picatinny\/MIL-STD-1913\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e AR-15, Modern Sporting Rifles, Tactical Carbines\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"American Defense Mfg.","offers":[{"title":"Default Title","offer_id":47943485522175,"sku":"ADMAD-509T-11-STD","price":114.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2853472.jpg?v=1766577871","url":"https:\/\/doublestackstore.com\/products\/am-def-holosun-509t-qr-lower-1-3","provider":"Double Stack Store","version":"1.0","type":"link"}
