When you are selecting a handguard for your AR15, you will want to be sure that it is simple to use, while at the same time durable enough for heavy-duty jobs. The Fortis SWITCH Fail System was designed with simplicity and durability in mind.

Handguards are designed to protect the user of an AR15 from exposure to the barrel, which can become extremely hot when in use. AR15s are known for their unique ability to be customized with accessories for multiple applications, from law enforcement to home defense to competitive shooting. Although it is possible to purchase a handguard without attachment points, the purchase of one equipped with a rail will provide extra bang for your buck.

The Fortis SWITCH 556 is specifically designed for an AR-15 platform. With QD attachment points, KeyMod slots on both sides, and a complete Picatinny rail on top, this free float rail system is sure to meet your needs. An innovative locking mechanism enables the user to remove the system without tools. Whether you are a police officer, a competitive shooter or someone who owns an AR-15 for home defense, the Fortis SWITCH is sure to meet your double need for hand protection and a place to attach your weapon’s accessories.
