Rise Armament RA-905 13.5" AR-15 Handguard - 6061-T6 Aluminum, Flat Dark Earth Cerakote, M-LOK & Picatinny Rail

The Rise Armament RA-905 13.5" AR-15 handguard combines a lightweight, rigid platform with practical mounting options for optics, lights, and accessories. Built from 6061-T6 aluminum and finished in Flat Dark Earth Cerakote, this mid-length handguard delivers durability and a professional look whether you're running a duty rifle, competition build, or hunting setup. The integrated M-LOK slots and top Picatinny rail give you flexibility to configure your AR exactly how you want it, without forcing you into a fixed rail system.

At 13.5 inches, the RA-905 strikes a practical balance—long enough to support modern optics and pressure switches, short enough to keep your rifle manageable in tight spaces or from a vehicle. The 6061-T6 aluminum construction keeps weight down while maintaining the stiffness you need for consistent accuracy. Flat Dark Earth Cerakote is a proven finish that resists corrosion and stands up to hard use in the field or on the range.

Whether you're building a precision rifle, refreshing an existing AR platform, or just looking to upgrade from a fixed front sight, the RA-905 works as a drop-in replacement and pairs well with standard AR-15 uppers and gas tubes. M-LOK attachment points let you run minimal, streamlined setups or go full-tactical with rails, lights, and pressure pads—your choice. The Picatinny section on top is perfect for mounting a quality scope or red dot without additional adapters.
