Daniel Defense Brings a GWOT Legend Back With the GL/SSC Rifle

Daniel Defense is bringing one of its most sought-after rifles back to the market with the return of the DD GL/SSC or the Grenade Launcher/Sound Suppressor Capable rifle.

The GL/SSC earned legendary status among SOCOM operators during the Global War on Terror. Originally developed in response to a SOCOM requirement for a rifle capable of mounting both an M203 grenade launcher and a suppressor in tandem without any restrictions, the GL/SSC became one of the rarest and most iconic rifles ever designed in Daniel Defense’s history.

During its original production run, only 125 rifles were manufactured, with just 25 making their way into civilian hands. For years, collectors and enthusiasts have attempted to replicate the configuration using surplus and aftermarket parts. Now, as part of the company’s 25th Anniversary celebration, Daniel Defense is bringing the GL/SSC back as a faithful reproduction available to the civilian market.

The modern GL/SSC retains the defining characteristics that made the original so desirable. The rifle features a 12.5-inch cold hammer forged government-profile barrel, a carbine-length gas system, and the iconic RIS II free-float quad rail. Most notably, the rail incorporates the integrated hanger system that allows for direct M203 mounting while maintaining suppressor compatibility.

The lower receiver remains true to the original concept, utilizing a standard Daniel Defense mil-spec lower receiver paired with a mil-spec trigger and buffer system.

Below is the product description from Daniel Defense:

Product Description

The legend returns. The once unobtainable GL/SSC

Some rifles aren’t just rare — they’re legendary. The GL/SSC is both. The original was so unobtainable that only 25 ever reached civilian hands — and even then, builders went to extraordinary lengths just to get close.

Now, for the first time, it’s available to the general public. The GL/SSC is built around a 12.5” Cold Hammer Forged Government profile barrel on a carbine-length gas system, paired with the iconic free-float RIS II rail and integrated hanger system for full M203 and suppressor compatibility. No workarounds. No compromises. The real thing.

• 12.5” chrome-lined, heavy-phosphate-coated government profile barrel.
• Free-floating GL/SSC RIS II. Integrates all M203 grenade launcher mounting components directly into the rail without additional parts or special tools. Provides real estate for accessories without affecting barrel harmonics.
• Chrome Moly Vanadium Steel, Cold Hammer Forged, 1:7 Twist, Government Profile, Chrome Lined, Mil-Spec Heavy Phosphate Coated, 12.5” Carbine Gas System.
• Compatible with suppressors and M203 mounting accessories via free-float hanger system.

Final Thoughts

The return of the GL/SSC gives enthusiasts an opportunity to own a rifle that was once nearly impossible to acquire. Between its military pedigree, limited production history, and unmistakable GWOT-era configuration, the GL/SSC remains one of the most recognizable rifles ever produced by Daniel Defense.

Whether you’re a collector, clone builder, or simply a fan of military small arms history, the GL/SSC represents a rare chance to own a faithful recreation of a rifle that helped define an era of modern warfare.

The Daniel Defense GL/SSC is available as an SBR, pistol, or upper receiver assembly. The SBR and pistol configurations retail for $2,026 MSRP, while the upper receiver assembly retails for $1,700 MSRP.
