The REV II free-float M-LOK rail will provide you with an easy-to-use and lightweight system. The REV II is made from aircraft grade 6061-T6 aluminum for superior strength and reliability.

The removal of the short three, six and nine o’clock forward rails on the REV 2 version permits a greater number of M-LOK slots than on previous REV models. The addition of QD sling swivels makes it easy for you to attach and remove your sling when desired. These changes to the REV system contribute to the lighter weight of the REV 2.

The Fortis REV 2 mounting system uses a standard AR15 barrel nut to make the installation of your new rail quick and easy. It is also piston-compatible. Order your rail replacement today to experience the Fortis difference!
