Modular Float Rail

Daniel Defense MFR (Modular Float Rail) | M-LOK®

The MFR Rail System from Daniel Defense utilizes the M-LOK mounting system to provide significant weight savings as well as excellent cooling, ergonomics, and modularity, while maintaining the strength and durability characteristic of Daniel Defense. M-LOK mounting points are located at 7 positions along the rail, and a continuous 1913 Picatinny rail runs along the top. Integrated sling swivel mounting points are located on both the left and right sides of the rail.

The slim bolt-up system increases stability and reduces the overall diameter of the rail, making it easier to control. The bolt-up system barrel nut is used. Anti-rotation tabs, included as standard, ensure easy installation and precise alignment. The MFR system is compatible with low-profile gas blocks attached to pistol, carbine, mid-length, or rifle-length gas systems.
