Fortis Manufacturing, Inc. Switch Handguard - Black

The Fortis Manufacturing Switch handguard is a lightweight free-float rail system built for AR platform rifles that demand versatility without the weight penalty. If you're running competition loads, hunting configurations, or just like the flexibility to swap rail systems without breaking out tools, the Switch delivers a modular approach backed by Fortis's reputation for precision manufacturing and real-world durability.

The standout feature is the patent-pending locking mechanism that lets you remove the rail system tool-free—a genuine advantage when you need to swap between mission-specific setups or simply clean without disassembly headaches. The handguard is machined from aircraft-grade 6061-T6 aluminum and hard-coat anodized for corrosion resistance and a finish that holds up to hard use. The locking handle uses stronger 7075-T6 aluminum, so it won't flex or fail under repeated cycling.

Mounting is straightforward: the barrel nut is 4140 heat-treated steel with a torque spec of 20 in. lbs. (you'll need a spanner wrench to dial it in properly). M-LOK slots run at the 3, 6, and 9 o'clock positions, plus an offset location, giving you multiple options for mounting lights, grips, rail sections, or whatever your setup calls for. The open venting at 12 o'clock keeps heat and noise signature down, and the 1.34" internal diameter fits standard AR uppers.

Built in the USA, the Switch balances minimalist weight with the rigidity you need for precision work or hard-running field use.

Frequently Asked Questions

What tools do I need to install the Switch handguard?

You'll need a spanner wrench to torque the barrel nut to the 20 in. lbs. specification. The spanner wrench is not included. Once the barrel nut is secure, the handguard itself installs without tools, and the tool-less locking mechanism allows you to remove or swap the rail without additional equipment.

Is the Switch compatible with my AR-15 or AR-10?

The Switch is designed for the AR platform with a 1.34" internal diameter. Confirm that your upper receiver matches this spec. If you're unsure about your specific build, contact us and we can help verify compatibility.

Can I swap out the rail system without removing the barrel nut?

Yes—that's the key advantage of the Switch. The patent-pending locking mechanism allows you to remove and change the rail itself without tools. The barrel nut stays torqued to the upper, so swaps are quick and don't require re-torquing during configuration changes.

What M-LOK options do I have for mounting accessories?

The Switch features M-LOK slots at the 3, 6, and 9 o'clock positions around the handguard, plus an offset location. The 12 o'clock position is vented (no M-LOK there) to reduce weight and heat signature.
