The Yankee Hill Machine M-LOK 2.75" Continuous Rail is a modular solution for shooters who want to expand their handguard's accessory real estate without replacing the whole system. Built for AR platforms and other rifles with M-LOK slots, this rail lets you mount standard Picatinny-compatible optics, lights, and accessories to your existing M-LOK handguard. If you're running a modern rifle and need flexibility to configure your setup as your shooting evolves, this is the kind of straightforward, well-engineered addition that actually gets used.

The rail is manufactured from 6061-T6 aluminum and hardcoat anodized for durability in the field. Stainless steel M-LOK fasteners are included, so corrosion isn't a concern even in wet conditions. At just 0.832 ounces, it adds negligible weight to your rifle. The 2.75-inch length gives you real estate to work with without overburdening your handguard geometry, and because YHM designed it as part of their Continuous M-LOK Rail System (C.M.R.S.), you can stack multiple sections end-to-end to create longer continuous Picatinny runs if your build demands it.

Whether you're setting up a hunting rifle, a range gun, or a defensive carbine, this rail fills the gap between M-LOK's growing popularity and the huge library of Picatinny-mounted gear already in circulation. It's a no-nonsense way to maintain compatibility without compromise.

Frequently Asked Questions

What kind of accessories can I mount on this M-LOK rail?

Any standard Picatinny-rail accessory: tactical lights, laser designators, optical sight adapters, backup iron sight bases, tactical grips, and more. If it has Picatinny mounting holes, it'll work with this rail.

Can I connect multiple M-LOK rails together?

Yes. This rail is part of YHM's Continuous M-LOK Rail System (C.M.R.S.), which means you can mount multiple sections end-to-end to create longer continuous Picatinny surfaces on your handguard.

Will the stainless fasteners rust or corrode?

Stainless steel is corrosion-resistant, so the included M-LOK screws and nuts are built to handle wet and harsh field conditions without degrading.

How much weight does this add to my rifle?

At 0.832 ounces, the weight is negligible and won't meaningfully affect your rifle's balance or handling characteristics.
