The Daniel Defense GL/SSC is a compact 5.56 NATO AR-platform firearm built around the once-rare GL/SSC configuration, pairing a 12.5" cold hammer-forged government-profile barrel with the distinctive free-floating RIS II GL/SSC rail. Designed around the military-inspired M203-compatible rail concept, it features a carbine-length gas system, chrome-lined bore, mil-spec heavy-phosphate barrel coating, DD A2 flash hider, integrated free-float hanger system & suppressor compatibility. Available as a pistol, SBR, or upper receiver group depending on configuration, the GL/SSC is intended for collectors, clone enthusiasts, tactical shooters & users wanting an authentic compact Daniel Defense platform with serious accessory support. Daniel Defense has a strong reputation for producing durable, hard-use AR platforms with premium barrels, properly engineered rail systems & excellent manufacturing consistency. The GL/SSC stands out because it brings back a historically significant & previously difficult-to-obtain configuration, centered on the RIS II rail developed for SOCOM’s SOPMOD II program & a 12.5-inch barrel that balances compact handling with useful ballistic performance. The chrome-lined cold hammer-forged barrel, 1:7 twist, carbine gas system, welded-quality rail interface & USA-made construction give the platform the durability expected from Daniel Defense. Overall, the GL/SSC is a specialized but highly effective AR configuration for shooters who value clone-correct styling, compact performance & proven Daniel Defense build quality.
