The Daniel Defense RIS III FSP Handguard Assembly (brand part number 01-004-02383-011) is a 13-inch free-float quad-rail handguard finished in Flat Dark Earth, cut to work with a fixed front sight post (FSP) rather than a low-profile gas block. It carries a continuous top picatinny rail for optics and iron sights, with shorter rail sections at 3, 6, and 9 o’clock for mounting lights, grips, and other accessories, all wrapped around a rigid free-float barrel nut for a rock-solid zero. As a genuine Daniel Defense part, it delivers the fit, finish, and reliability the company is known for on duty and competition rifles alike.
