M-LOK ARCA Rail

We stock the Magpul M-LOK ARCA Rail (the M-LOK Dovetail Adapter for the RRS®/ARCA® interface) for precision and long-range shooters who want to run tripods and bipods straight off an M-LOK forend. It's a lightweight, machined, Mil-Spec hard-anodized aluminum mounting plate that bridges your rifle to the RRS Dovetail Standard, so it drops right into most ARCA-compatible clamps.

Bolt it to any M-LOK-slot handguard and you've got a fast, repeatable interface for bipods, tripods, and other RRS/ARCA accessories — a real advantage when you're building a stable position on a Texas sendero, a backcountry glassing knob, or a prairie dog town where the wind never quits.

The adapter is built for hard use. Multiple drilled and tapped holes are placed to limit accessory travel, the beveled edges are snag-resistant so nothing catches on pack straps or brush, and the recoil/impact mitigation lugs keep it locked in place through the heaviest recoil impulses. The result is a rugged, repeatable, precise mounting solution.
