MDT M-LOK ARCA Rail, 3.3-Inch Black Anodized

The MDT M-LOK ARCA Rail (MDT part no. 103416BLK) gives any M-LOK-equipped rifle a direct Arca-Swiss interface, the mounting standard that has become the go-to way to attach precision rifles to tripods, bipods, and other support gear. Rather than requiring an MDT chassis, this rail bolts to standard M-LOK slots, so shooters running other free-float handguards can add Arca-Swiss compatibility without swapping their whole fore-end. MDT finishes the rail in a Mil-Spec Type II hard-black anodized coating for durability, and it is available in a standard flat profile that fits most M-LOK surfaces or an angled profile shaped to match the underside of the MDT LSS-XL Gen2.
