Magpul M-LOK Dovetail Adapter Pro Chassis Full Rail for RRS/ARCA Interface - Aluminum Matte

The Magpul M-LOK Dovetail Adapter Pro Chassis Full Rail bridges the gap between modern M-LOK handguards and the RRS/ARCA interface standard that's become the go-to mounting system for precision rifle shooters. If you're running a modular precision rifle and want to attach ARCA-compatible bipods, tripod heads, or other accessories without swapping your entire handguard setup, this aluminum adapter gives you that flexibility in a clean, purpose-built package.

Magpul machined this adapter from aluminum and hard-coat anodized it for the kind of durability you'd expect from a USA-made component. The edges are beveled during production to reduce snag points, and the whole design occupies two M-LOK slots on your handguard. The Pro Chassis variant includes a thoughtful cutout that lets Pro 700 chassis users remove the front action screw without unbolting the adapter—a detail that shows Magpul was thinking about real-world workflow. The adapter ships drilled and tapped at multiple points; those reference holes not only give you mounting options but also prevent hardware overtravel, keeping your setup tight and predictable.

Whether you're dialing in at a precision rifle range, setting up for a long-range hunt, or running a modular competition build, this adapter lets you leverage the ARCA standard without committing to a new handguard. It's the kind of incremental upgrade that unlocks a lot of flexibility once you've invested in RRS or ARCA gear.
