The K1 lockdown system uses a tapered castle nut that seats and seals onto the end plate for an ultra-precision, snug fit. Built from 7075-T6 aircraft-grade aluminum and finished in anodized black\/gray, this robust, minimalist design eliminates ratcheting mechanisms and set screws while keeping weight extremely low. A 360° rotational quick-detach (QD) socket interface adds sling-mount versatility for hard-use setups.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eK1 tapered castle nut design helps lock in place without staking the end plate\u003c\/li\u003e\n  \u003cli\u003eLightweight Enhanced (LE) system keeps total weight to approximately 0.59 oz (16.8 g)\u003c\/li\u003e\n  \u003cli\u003e7075-T6 aircraft-grade aluminum construction for strength with minimal bulk\u003c\/li\u003e\n  \u003cli\u003e360° rotational QD socket interface for flexible sling attachment positioning\u003c\/li\u003e\n  \u003cli\u003eNo set screws and no ratcheting mechanism for a clean, streamlined installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Fortis Manufacturing, Inc.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Castle nut \u0026amp; end plate system\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLockdown System:\u003c\/strong\u003e K1 (tapered castle nut, no staking required)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlatform:\u003c\/strong\u003e AR-15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 7075-T6 aircraft-grade aluminum (castle nut and end plate)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Anodized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\/Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuick Detach (QD) Interface:\u003c\/strong\u003e 360° rotational locking interface\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Approx. 0.59 oz \/ 16.8 g (total)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Manufacture:\u003c\/strong\u003e USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 850015927188\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e LE-BLK-K1-GRY\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003ci\u003eDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
