The dual-aperture design flips between a large ring for fast, close work and a small aperture for precision at distance — the classic combat configuration, executed with machined precision. Windage adjusts tool-lessly with positive, audible clicks, so refining zero at the range needs nothing but your fingers.\u003c\/p\u003e\u003cp\u003eFolded, the sight sits extraordinarily low and snag-free; deployed, it locks up without play and returns to zero shot after shot. Paired with an MBUS Pro front, you get a sighting system tough enough to serve as primary irons on a dedicated build — and dependable enough to bet on when an optic goes down.\u003c\/p\u003e\u003ch3\u003eWhy shooters choose the MBUS Pro Rear\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAll-steel construction\u003c\/strong\u003e — built to take what polymer cannot\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual apertures\u003c\/strong\u003e — fast ring up close, fine aperture at distance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool-less windage adjustment\u003c\/strong\u003e — crisp, positive clicks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra-low folded profile\u003c\/strong\u003e — clean under optics, snag-free\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrue return to zero\u003c\/strong\u003e — deployment after deployment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat the MBUS Pro Rear fits\u003c\/h3\u003e\u003cp\u003eFits 1913 Picatinny top rails on AR-15\/M4 pattern rifles, at the rear of the receiver rail in the usual backup sight position. Make sure there is clear rail behind your optic or mount before ordering, and that the front and rear sit on the same rail plane. It pairs with any MBUS Pro front sight; elevation is normally set on the front sight, so zero the pair together.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePlatform\u003c\/th\u003e\n\u003ctd\u003eAR-15 \/ M4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eDual-aperture flip-up rear sight\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eSteel\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 top rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAdjustment\u003c\/th\u003e\n\u003ctd\u003eTool-less windage\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\u003eMAG276\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003eFinish the system properly. \u003cstrong\u003eOrder the MBUS Pro Rear 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\/iron-sights-backup-sights\"\u003eIron Sights \u0026amp; Backup Sights\u003c\/a\u003e, \u003ca href=\"\/collections\/ar-15-parts-accessories\"\u003eAR-15 Parts\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":60873787441486,"sku":"MAG276","price":125.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1081\/3223\/7646\/files\/magpul-mbus-pro-sight-rear-1-1.jpg?v=1789881032","url":"https:\/\/onyxarmaments.co.uk\/products\/magpul-mbus-pro-sight-rear-1","provider":"Onyx Armaments","version":"1.0","type":"link"}
