Frequently Asked Questions
Will the Fortis Switch Rail 15.3" fit my AR-15 build?
The Fortis Switch Rail Mod 1 is designed specifically for the AR-15/MSR platform and uses a standard barrel nut included with the handguard. It features a 1.34" internal diameter, which clears most standard and mid-profile gas blocks. As always, confirm your gas block profile and barrel nut compatibility before installation. If you have questions about fitment for your specific build, contact Goodland Guns for assistance.
How does the tool-less locking mechanism work?
The SWITCH Rail's patent-pending locking handle allows you to remove and swap accessory rail sections without tools. The handle locks securely into place during use, preventing any movement or rattle, but can be released quickly when you need to change your accessory configuration. This makes the Fortis SWITCH ideal for competitors who need to adapt their rifle between stages or disciplines without carrying a full tool kit.
Can I mount a bipod, light, or foregrip on this handguard?
Yes. The Fortis Switch Rail 15.3" M-LOK Mod 1 features M-LOK slots along the sides and bottom of the handguard, allowing you to mount any M-LOK-compatible accessory including bipods, weapon lights, angled foregrips, and vertical grips. The continuous top Picatinny rail accommodates optics, iron sights, and backup sighting systems across the full length of the handguard.
