The Fortis SWITCH™ 556 MOD 2 Rail System is built for shooters who demand precision, strength, and speed. This 13.8-inch AR-15 M-LOK handguard represents the next generation of the SWITCH™ series—refined, lightweight, and engineered for ultimate performance. Every feature was designed with real-world function in mind, giving you faster handling, better heat dissipation, and rock-solid reliability under pressure.

Reimagined for Modern Shooters

The MOD 2 series takes everything great about the original SWITCH™ and makes it even better. Fortis removed the 12 o’clock Picatinny section and replaced it with open vents, reducing weight and improving airflow around the barrel. This streamlined design not only looks sharp but keeps your rifle running cooler and lighter during sustained fire.

The slimmer profile provides a more natural grip for dynamic handling, and the revised geometry allows for smoother transitions between targets. Whether you’re running drills or competing in precision rifle matches, the Fortis MOD 2 rail gives you complete control without compromise.
