Unmatched Design & Performance
The Camber Rail System was created for shooters who won’t settle for “good enough.” Fortis Manufacturing re-engineered the mounting system from the ground up to provide superior alignment, precision, and strength. The Camber Lock™ system distributes tension evenly around the barrel nut, creating a complete lockup that eliminates rotation or flex.
This design gives you the confidence to run your rifle hard — whether you’re training, competing, or operating in the field. And thanks to its free float architecture, your barrel remains completely isolated from external forces, preserving accuracy even under heat or recoil.
The result? A rail system that’s incredibly rigid, visually striking, and engineered for modern tactical performance.
