The Daniel Defense GL/SSC RIS II Upper Receiver Group, 5.56 NATO, 12.5" Government Profile Barrel, Carbine-Length Gas System, RIS II Free-Float Rail, FDE brings the once hard-to-find GL/SSC configuration back in a compact, ready-to-pin-on package. This complete upper pairs a 12.5 inch cold hammer forged government profile barrel with the battle-proven GL/SSC RIS II free-float quad rail, giving shooters a rigid, accessory-ready platform that keeps weight forward of the receiver balanced and controllable.

Designed as an assembled upper receiver group, this model is ideal for building a premium AR-15 when matched with any mil-spec lower. The carbine-length gas system and chrome-lined 5.56x45 NATO barrel support reliable cycling and long service life, while the Flat Dark Earth RIS II rail offers generous Picatinny space for lights, lasers, and aiming accessories. It is well suited for range use, training, and enthusiasts seeking a historically inspired configuration with modern performance, backed by Daniel Defense’s reputation for precise machining and durable components.
