The Fortis SWITCH™ 308 MOD 2 17" M-LOK Rail System is the definition of innovation and precision for AR-10 builders who refuse to compromise. Designed for the DPMS high-profile .308 platform, this free float rail combines rock-solid performance, effortless installation, and the modern modularity that today’s shooters demand.

Every Fortis rail starts with 6061-T6 aircraft-grade aluminum, CNC-machined to exacting tolerances for exceptional strength and perfect alignment. The result is a rail that’s lightweight yet remarkably rigid, offering stability under recoil and accuracy you can count on.

Fortis’ engineers took the original SWITCH design and refined it — the MOD 2 version introduces an improved locking mechanism that delivers a tighter, more secure fit, while allowing tool-less removal for cleaning or mission-specific changes.

Whether you’re competing, hunting, or running a tactical rifle, the Fortis SWITCH™ 308 MOD 2 Rail is built to exceed expectations.

Why the Fortis SWITCH™ MOD 2 308 Rail Stands Out

The Fortis SWITCH MOD 2 isn’t just another free float handguard — it’s a masterclass in engineering simplicity and reliability.

This system was designed around one idea: to make maintenance and modularity easier without sacrificing precision. The patent-pending cam lever locking mechanism lets you remove or swap the rail in seconds while maintaining zero. It locks down with complete barrel nut engagement, giving your rail 360° of structural contact for unmatched rigidity.

The 17-inch model offers the ideal balance of length, weight, and coverage, perfectly suited for 18" or 20" .308 barrels. With M-LOK slots along the 3, 6, and 9 o’clock positions and offset angles, you’ll have full flexibility for accessories while maintaining a slim, comfortable grip.

Technical Specifications

Installation & Compatibility

The SWITCH MOD 2’s tool-less installation system is a game-changer for AR-10 builders.
Once the barrel nut is torqued to spec (32 in-lbs), the rail slides on and locks securely into place using Fortis’ signature cam lever mechanism. This allows quick removal for barrel cleaning, maintenance, or changing configurations — all without disturbing your optics or zero.

Compatible with DPMS high-profile .308 receivers, this rail works perfectly with mid- and rifle-length gas systems.

No special tools. No frustration. Just precision engineering designed to make your rifle better.
