YHM ARCA-SWISS 10″ M-LOK RAIL ASSY

Description

Attaching a bipod, tripod head, or shooting rest to an M-LOK handguard has traditionally meant adding a separate adapter that introduces its own layer of slop and potential movement. The Yankee Hill Machine Arca-Swiss M-LOK Rail solves that by giving you a dedicated Arca-Swiss dovetail surface that mounts directly into your existing M-LOK slots, so the connection between your chassis-style accessories and the rifle stays as short and rigid as possible.

YHM built this rail to the RRS Dovetail standard, which is worth understanding before you buy. Arca-Swiss is a broad category, not a single unified specification, and rails manufactured to different interpretations of that geometry can bind or slip when combined. If your bipod or clamp head was made to a different Arca standard, confirm compatibility before purchasing rather than assuming any dovetail will mate with any other.

The rail is machined from 6061-T6 aluminum and finished with a Hard-Coat Anodize, a combination that keeps weight low while providing a surface hard enough to withstand the repeated clamping pressure that Arca-style accessories apply directly to the rail face. At 10 inches, it gives you enough dovetail length to make meaningful fore-and-aft adjustments to bipod or rest position without repositioning the rail itself — useful when you are dialing in balance on a precision or field-shooting build. Width comes in at 1.5 inches, and the assembly weighs 5.1 ounces. The rail is manufactured in the United States.
