The MFR XL Rail Systems from Daniel Defense utilize the M-LOK attachment system for incredible weight savings as well as superior cooling, ergonomics, and modularity while maintaining the strength and durability expected from Daniel Defense. M-LOK attachment points are located along the sides and bottom on the rail and feature an uninterrupted 1913 Picatinny rail on top. Its sleek bolt-up system increases strength and allows for easy installation. The increased internal diameter gives the operator the ability to attach a suppressor and have the proper clearance needed for installation. Anti-rotation tabs come standard for ease of installation and alignment. The MFR can be used with a pinned low-profile gas block on pistol, carbine, mid-length or rifle length gas systems.

Excellent Rail. Mounting screws need to be better.I purchased 2 of these and I very pleased with the size and the look on each unit. The accessory attachment The only issue is the 4 mounting screws are less than adequate in grade. I ordered replacements and also used store bought screws that are heavier grade that won't strip when moderate pressure is placed on them. A slightly deeper counter-bore the plate to allow for a larger screw head would be excellent. Perhaps a Torx head would be a better option here as well. I would really like to see these offered in an 8" or 7" model as well. Thank you Daniel Defense for a very nice rail.
