The Daniel Defense MFR M-LOK to QD Sling Mount (brand part no. 03-021-15136) is designed specifically for the Daniel Defense MFR Rail, giving it a push-button sling swivel attachment point at designated locations on both sides of the rail for tangle-free, ambidextrous sling use. Because it mounts at fixed points front and rear on the MFR system, the sling stays put rather than rotating freely around the handguard, which keeps it from tangling during transitions. This mount is compatible with the MFR Rail, Omega Rail, and DELTA 5 Stock, but it is not compatible with the MFR XL Rail, DD5 Rail, or M-LOK rail systems from other manufacturers, so confirming your specific rail before ordering matters. It is a fitted, purpose-built solution rather than a universal M-LOK adapter from Daniel Defense.
