An offset dot beside a magnified optic, with zero change in cheek weld.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA magnified optic is the right answer until something appears at fifteen metres. The usual fix is a second sighting system canted off the main rail, and the detail that decides whether it actually works is whether you have to move your head to use it. Daniel Defense's offset rail is designed so there is no change in cheek weld during the transition — you roll the rifle slightly and the dot is there.\u003c\/p\u003e\u003cp\u003eIt is optimised for miniature red dot optics and takes any MIL-STD-1913 accessory, so it is equally useful for a light. Inverted, it positions a light clear of a vertical foregrip. It mounts with Daniel Defense's patented Rock \u0026amp; Lock one-piece system, is machined from aircraft-grade 6061-T6 aluminium, is Military Specification Type III hard-coat anodised, weighs 1.1 oz (31 g) and is made in the USA.\u003c\/p\u003e\u003cp\u003eOn a UK straight-pull AR-15 running a magnified scope for deliberate shooting, an offset dot is the cheapest way to keep a close-range option without touching the primary optic's zero or its mount.\u003c\/p\u003e\u003ch3\u003eWhy shooters choose the 1 O'Clock Offset Rail\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo cheek weld change\u003c\/strong\u003e — the transition is a roll of the rifle, not a repositioning of your head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimised for miniature red dots\u003c\/strong\u003e — the intended job, and the reason the angle is what it is\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1 o'clock or 11 o'clock\u003c\/strong\u003e — invert it and the same part serves a left-handed shooter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTakes any 1913 accessory\u003c\/strong\u003e — useful for a light as well as an optic, including inverted beside a foregrip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRock \u0026amp; Lock one-piece mounting\u003c\/strong\u003e — patented, and simple to fit and remove\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1.1 oz (31 g)\u003c\/strong\u003e — 6061-T6 aluminium, Type III hard-coat anodised\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat the 1 O'Clock Offset Rail fits\u003c\/h3\u003e\u003cp\u003eFits any MIL-STD-1913 Picatinny rail on AR-type rifles, including UK straight-pull AR-15 builds — normally the top rail of a flat-top upper or a rail-topped handguard. You need enough continuous rail beside or ahead of your primary optic for the mount to clamp onto, so check the space you have before ordering. The offset rail carries the optic's own mount, so a miniature red dot with a standard Picatinny footprint attaches to it exactly as it would to the receiver rail. Inverted, it sits at 11 o'clock for a left-handed shooter, or below the centreline to position a light clear of a vertical foregrip.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePlatform\u003c\/th\u003e\n\u003ctd\u003eAR-15 \/ M4, and any MIL-STD-1913 rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFits\u003c\/th\u003e\n\u003ctd\u003eMIL-STD-1913 Picatinny rail; miniature red dot optics and other 1913 accessories\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eOffset rail section at 1 o'clock, reversible to 11 o'clock\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eAircraft-grade 6061-T6 aluminium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eMilitary Specification Type III hard-coat anodised\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e1.1 oz (31 g)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMount interface\u003c\/th\u003e\n\u003ctd\u003ePatented Rock \u0026amp; Lock one-piece mount to MIL-STD-1913 Picatinny\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMade in\u003c\/th\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eDaniel Defense\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMPN\u003c\/th\u003e\n\u003ctd\u003e03-029-13017\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003eA close-range answer that costs you nothing in position. \u003cstrong\u003eOrder the Daniel Defense 1 O'Clock Offset Rail today\u003c\/strong\u003e — in stock at Xtreme Tactical Gun Parts with free tracked UK delivery in 7–10 days.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eExplore more:\u003c\/strong\u003e \u003ca href=\"\/collections\/ar-15-parts-accessories\"\u003eAR-15 Parts \u0026amp; Accessories\u003c\/a\u003e or browse all \u003ca href=\"\/collections\/daniel-defense\"\u003eDaniel Defense\u003c\/a\u003e.\u003c\/p\u003e","brand":"Daniel Defense","offers":[{"title":"Default Title","offer_id":42843570339920,"sku":"03-029-13017","price":84.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0550\/4978\/1328\/files\/DD03-029-13017_1_HR.jpg?v=1786566302","url":"https:\/\/xtremetacticalgunparts.co.uk\/products\/daniel-defense-1-oclock-offset-rail","provider":"Xtreme Tactical Gun Parts","version":"1.0","type":"link"}
