Modular Float Rail | XL

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

The MFR XL 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 on the sides and bottom of the rail, while a full-length 1913 Picatinny rail runs along the top. The slim bolt-up system increases stability and simplifies installation. The enlarged inner diameter allows for the mounting of a suppressor with the necessary clearance for installation. Standard anti-rotation tabs ensure easy installation and alignment. The MFR system can be used with a pinned low-profile gas block on pistol, carbine, mid-length, or rifle-length gas systems.
