The Daniel Defense 1 O’Clock Offset Rail (brand part no. 03-029-13017) is built for mounting a miniature red dot in the 1 o’clock position for right-handed shooters, or the 11 o’clock position when flipped for left-handed use, giving a fast, non-magnified backup sight alongside a primary magnified optic. Its geometry holds zero cheek-weld shift during the transition, so you can snap from a magnified scope to the offset red dot and back without breaking your position on the gun. Beyond optics, the rail mounts to any MIL-STD-1913 Picatinny interface and works equally well for lights or other accessories, including flipped upside-down to position a light for use with a vertical foregrip.
