MDT- M-LOK ARCA RAIL (7")

ARCA Standard. Mil-Spec Anodized. Built for MDT Chassis.

The MDT M-LOK ARCA Rail is the purpose-built solution for attaching your MDT chassis rifle to any ARCA-compatible tripod, bipod, or support system. Machined from 6061-T6 aluminum with a Mil-Spec Type III hard black anodized finish and machined to the Really Right Stuff (RRS) ARCA standard, this rail delivers a precise, repeatable ARCA interface on any M-LOK compatible surface — with the thoughtful design details that serious precision shooters expect from MDT.

Overview

ARCA Swiss adapters have become the standard for attaching rifles to tripods and support gear in precision shooting — and the MDT M-LOK ARCA Rail brings that capability to any M-LOK compatible chassis, stock, or handguard. The flat profile design adapts to most M-LOK surfaces, while 14 drilled and tapped holes allow precise accessory indexing for consistent, repeatable positioning. A rearward overhang positions your rifle closer to its center of gravity on a tripod, and the angled front surface eases tripod engagement while reducing snagging during deployment.
