Daniel Defense 1 O’clock Offset Rail (Rock & Lock)
The Daniel Defense 1 O’clock Offset Rail is optimized for mounting miniature red dot optics at the 1 o’clock (right-hand) or 11 o’clock (left-hand) positions for quick, non-magnified transitions when using magnified primary optics on AR-style rifles with MIL-STD-1913 rails. The geometry allows for zero cheek weld shift during transition, facilitating ultra-fast transitions from magnified to non-magnified optics and back. The 1 O’clock Offset Rail can also be used to mount various lights or other MIL-STD-1913 rail-mounted accessories. By flipping the part, a light can be positioned for use with a vertical foregrip.
2014. The updated 1 O’Clock Offset Rail now utilizes our patented Rock and Lock™ one-piece mounting system, creating an even more robust and streamlined mounting surface and simplifying installation on any MIL-STD-1913 Picatinny rail.
All Daniel Defense rails are built to the 1913 Military Specification and are 100% quality assurance checked for compliance.
