Daniel Defense MFR 9.0 M-LOK Rail Assembly – Black

The Daniel Defense MFR 9.0 M-LOK Rail Assembly is a free-floating handguard designed for AR-15 platform rifles. This 9-inch rail provides a lightweight, low-profile mounting solution with integrated M-LOK slots at the 3, 6, and 9 o'clock positions for direct attachment of accessories without additional rail sections. The continuous 12 o'clock Picatinny rail allows for co-witness iron sights or optic mounting.

Constructed from 6061-T6 aluminum with a Type III hard-coat anodized finish in black, the MFR (Modular Float Rail) uses a proprietary barrel nut system for secure attachment to mil-spec upper receivers. The slim 1.5-inch outer diameter and M-LOK design reduce weight while maintaining structural rigidity. Installation requires a barrel nut wrench (not included) and basic armorer tools.
