Up top, it has a continuous Picatinny/STANAG-style rail that includes visible slot index markings (for example, T2 through T12), providing a consistent mounting surface along the receiver and handguard. The handguard is a free-float M-LOK-style design, keeping the front end clean and straightforward.
