Machined for a precise rail fit and finished in a hard-wearing black, it sits tight against the rail with minimal overhang — no rattle, no bulk, no snag points.\u003c\/p\u003e\u003cp\u003eSling attachment placement makes or breaks how a rifle carries and mounts. The RSA QD lets you put the front sling point exactly where it balances the rifle for your build and your body, rather than where the factory happened to leave a loop. Paired with any push-button QD swivel it gives positive, silent lock-up that shrugs off hard use.\u003c\/p\u003e\u003ch3\u003eWhy shooters choose the RSA QD\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdds a QD socket to any Picatinny rail\u003c\/strong\u003e — place your sling point precisely\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow-profile machined body\u003c\/strong\u003e — tight fit, no rattle, no snags\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePositive QD lock-up\u003c\/strong\u003e — secure under load, silent on the move\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast installation\u003c\/strong\u003e — basic tools, minutes of work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat the RSA QD fits\u003c\/h3\u003e\u003cp\u003eClamps to any 1913 Picatinny rail section — handguard rails, receiver rails or rail panels. You need enough clear rail for the clamp body, so plan around your existing lights, grips and rail covers; an M-LOK-only handguard would need a rail section adding first. Seat it against a rail slot so recoil cannot walk it forward, then click in any standard push-button QD swivel such as the Magpul QDM (MAG543).\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eQD sling attachment point\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMount interface\u003c\/th\u003e\n\u003ctd\u003e1913 Picatinny rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eMagpul Industries\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMPN\u003c\/th\u003e\n\u003ctd\u003eMAG337\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003ePut your sling exactly where it belongs. \u003cstrong\u003eOrder the RSA QD today\u003c\/strong\u003e — imported from the USA with all duties paid by us and dispatched tracked from the UK in 7–10 business days, with nothing to pay on delivery.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eExplore more:\u003c\/strong\u003e \u003ca href=\"\/collections\/rifle-slings-sling-mounts\"\u003eRifle Slings \u0026amp; Sling Mounts\u003c\/a\u003e, \u003ca href=\"\/collections\/ar-15-parts-accessories\"\u003eAR-15 Parts \u0026amp; Accessories\u003c\/a\u003e or browse all \u003ca href=\"\/collections\/magpul-industries\"\u003eMagpul\u003c\/a\u003e.\u003c\/p\u003e","brand":"Magpul Industries","offers":[{"title":"Default Title","offer_id":60873788326222,"sku":"MAG337","price":44.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1081\/3223\/7646\/files\/magpul-rsa-qd-rail-sling-attachment-qd-mag337-1.jpg?v=1789881041","url":"https:\/\/onyxarmaments.co.uk\/products\/magpul-rsa-qd-rail-sling-attachment-qd-mag337","provider":"Onyx Armaments","version":"1.0","type":"link"}
