The Fortis SWITCH™ 556 MOD 2 Rail System represents the next evolution in Fortis innovation — built for shooters who demand lightweight strength, precision fit, and unmatched modularity. Designed for the AR-15 platform, this 15.3-inch free float M-LOK handguard delivers the perfect blend of rigidity, performance, and modern aesthetics.

Whether you’re upgrading your duty rifle, building a precision AR, or looking to enhance your rifle’s balance and control, the SWITCH™ MOD 2 delivers professional-grade performance that exceeds expectations.

Fortis Engineering: Strength Through Design

The SWITCH™ MOD 2 builds on Fortis’ original quick-detach system with enhanced features, improved airflow, and reduced weight. The 12 o’clock Picatinny section was replaced with open vents for better heat dissipation and a more ergonomic grip. The result is a handguard that runs cooler, feels slimmer, and handles faster in every shooting scenario.

Crafted from 6061-T6 aircraft-grade aluminum and finished with Type III hardcoat anodizing, the MOD 2 combines lightweight construction with uncompromising durability. Its patent-pending locking mechanism allows tool-free installation and removal, giving shooters the ability to swap or clean rails in seconds.
