Fortis Switch Rail 13.0" M-LOK Mod 1 Handguard

The Fortis Switch Rail 13.0" M-LOK Mod 1 Handguard is a free-floating AR-15 rail system built for shooters who want a lightweight, modular platform without compromise. At 13 inches, it strikes a practical balance—long enough to get your hands forward and anchor accessories, short enough to keep your AR nimble for hunting, tactical training, or range work. The M-LOK slot pattern gives you genuine modularity: mount lights, grips, bipods, or foregrips exactly where you need them, and swap gear without tools or permanent modifications.

Fortis engineered the Switch Mod 1 with precision machining and a no-nonsense design. The rail is built tough enough for hard use, yet the profile and material selection keep weight down where it matters. Free-floating construction isolates the barrel from the handguard, which helps consistency—especially relevant if you're dialing in a precision rifle or want repeatable zero across different shooting positions. The black finish is durable and blends seamlessly with standard AR uppers.

If you run an AR-15 and you're tired of generic plastic rails or rail systems that force you into a single grip style and accessory layout, the Fortis Switch Mod 1 rewards your build with real capability and flexibility. It's the kind of handguard that stays on your rifle through multiple configurations and upgrades because it's solid enough to trust and modular enough to adapt.

Frequently Asked Questions

What AR-15s does the Fortis Switch Mod 1 fit?

This handguard is designed for standard AR-15 platforms. It replaces the factory handguard on most mil-spec AR-15 uppers. If you have a proprietary upper or non-standard receiver setup, verify compatibility before purchase.

Can I mount a bipod or foregrip to this rail?

Yes. The M-LOK slot pattern allows you to mount bipods, foregrips, lights, and other accessories designed for M-LOK. M-LOK mounts are secure, tool-free adjustments, and you can position them along the entire rail length.

Is this rail free-floating?

Yes. The Fortis Switch Mod 1 is engineered as a free-floating rail, meaning the barrel does not make contact with the handguard. This design helps support consistent accuracy by isolating barrel vibration from the rail system.

What's included with the handguard?

The handguard is sold as the rail only. Installation hardware, barrel nuts, or gas tube components are not included; you'll need your upper receiver assembly tools and a compatible barrel nut for installation.
