MDT Sporting Goods M-LOK ARCA Rail 3.30" Black Anodized 6061-T6 Aluminum Mount

The MDT M-LOK ARCA Rail is a 3.30" long mounting plate that brings ARCA Swiss (RRS) compatibility to any rifle equipped with an M-LOK compatible handguard. It provides a clean, repeatable dovetail interface for clamping your rifle into ARCA-spec bipods, tripods, and quick-detach shooting accessories.

Machined from lightweight 6061-T6 aluminum and protected by a mil-spec hard black anodized finish, the rail clamps directly to existing M-LOK slots for a low-profile, secure mount on your handguard. The dovetail geometry follows the standard ARCA Swiss / Really Right Stuff specification, so it interfaces with the widest range of accessories on the market.

At 3.30", this rail is sized for carbine-length handguards and compact builds where you want full ARCA functionality without the footprint of a longer mounting plate. Pair it with an ARCA clamp for fast, repeatable positioning on bags, tripods, or barricades.
