Magpul M-LOK Dovetail Adapter Black, 2 Slot, RRS/ARCA Interface, Precision Mounting Solution

The Magpul M-LOK Dovetail Adapter Black, 2 Slot gives precision rifle shooters a clean, direct way to run RRS/ARCA-compatible bipods and accessories on M-LOK handguards. If you've standardized on the ARCA-Swiss dovetail interface for your precision setup, this adapter bridges the gap between that system and your M-LOK rail without compromise. It's a straightforward solution for shooters who want the rigidity and modularity of RRS/ARCA mounting without the headache of mismatched interfaces.

Built from aluminum and hard-coat anodized for durability, the adapter machines clean with beveled edges to keep snags and dings out of your day at the range or field. It fills exactly two M-LOK slots on your handguard, so you know exactly where it sits and how much rail real estate you're using. Magpul drilled and tapped the interface at multiple points to let you dial in your optics or bipod placement precisely, and those holes also serve as hard stops to prevent your attachment from creeping during shooting.

Every adapter is designed and built in the USA. The 2-slot version measures 3.15 inches long, 1.50 inches wide, and 0.20 inch tall—sized to balance footprint with load-bearing surface. It works seamlessly with all standard RRS dovetail accessories, making it the go-to choice for shooters moving between platforms or integrating ARCA-based gear into an M-LOK setup.
