Product Code: DD-03-029-13017

Product Weight: 1.1 oz (31.18g)


The Daniel Defense 1 O’clock Offset Rail is optimised for mounting miniature red dot optics in the 1 O’clock (right-hand) or 11 O’clock (left-hand) positions for quick, non-magnified, transitions when employing magnified primary optics on AR-type rifles with MIL-STD-1913 rails. The geometry allows for zero cheek-weld shift during the transition. This facilitates very fast transitions from magnified to non-magnified optics, and back. The 1 O’clock Offset Rail can also be used to mount a variety of lights or other accessories that mount to a MIL-STD-1913 rail. By flipping the part upside-down, one can mount a light in a good position for use with a vertical foregrip. 


Updated for 2014, the 1 O’Clock Offset Rail now utilises the patented Rock and Lock™ one-piece mounting system, creating an even more robust and streamlined mounting surface as well as



  • Optimised for Miniature Red Dot Optics
