Yhm Arca-Swiss 6" M-Lok Rail Assy

The Yhm Arca-Swiss 6" M-Lok rail assembly bridges your modern AR handguard and precision tripod gear. Whether you're setting up a dedicated shooting platform, building a tactical rifle for long-range work, or mounting optics on a stable base, this rail gives you a standardized mounting interface that talks to the full ecosystem of Arca-Swiss tripod adapters and accessories. Built from 6061-T6 aluminum, it slides onto any M-Lok compatible handguard and locks down solid—no proprietary systems, no hassle.

If you're running a modern rifle with M-Lok slots, you've probably noticed the mismatch: your handguard works great for mounting lights and covers, but what about connecting to a tripod, monopod, or shooting rest? That's where the Arca rail solves a real problem. It gives you a unified attachment point that works with RRS dovetail standard accessories and most Arca-Swiss gear out there, so you're not locked into one brand's ecosystem.

At 6 inches, it's sized to give you genuine mounting surface without taking over your entire rail real estate. The aluminum construction keeps weight reasonable, and the design assumes you're serious enough to want repeatability and compatibility as much as capability. Install it once, zero it in, and move tripod heads between rifles without drama.

What tripod heads and accessories are compatible?

It's built to the Arca-Swiss standard and compatible with RRS dovetail standard gear, so you can use most modern Arca-Swiss tripod heads, clamps, and accessories designed to that spec.

How much weight does it add?

It's aluminum construction, but exact weight isn't specified in the product details—contact us for precise specs if weight-sensitive builds are your priority.

Is this a complete handguard or just a rail accessory?

This is a rail assembly that mounts to an existing M-Lok handguard. You'll need a compatible handguard already on your rifle.
