25th Anniversary GL/SSC Reissue

Daniel Defense celebrates its 25th anniversary by bringing back the legendary GL/SSC configuration. The original GL/SSC was a slightly shorter RIS II variant intended for 12.5-inch barrel use, maintaining grenade launcher mounting ability in a more compact package. The new production GL/SSC rails are marked "Savannah, GA" rather than the "Black Creek, GA" markings of the original 125 units, making the true OG rails distinguishable for collectors.

12.5" Cold Hammer Forged Barrel

The 12.5-inch barrel is cold hammer forged from 4150 Chrome Moly Vanadium steel—an intense hydraulic pressure process that forms the most accurate and longest-lasting barrels attainable. The government profile barrel features chrome-lined bore and Mil-Spec heavy phosphate coating for exceptional durability and corrosion resistance. The 1:7 twist rate stabilizes a wide range of bullet weights including heavier 77-grain match ammunition. Threaded 1/2x28 for muzzle device attachment.

Carbine-Length Gas System

The carbine-length direct impingement gas system with internal hammer firing system ensures reliable cycling with both 5.56 NATO and .223 Remington ammunition. The low-profile gas block is pinned to the barrel for secure attachment.

GL/SSC RIS II 11.5" FDE Quad Rail System

The free-floating, battle-proven GL/SSC RIS II Rail System provides real estate for accessories without affecting barrel harmonics. This slightly shorter variant of the standard RIS II retains the grenade launcher mounting ability of the original through its versatile two-piece design. The quad rail configuration offers four continuous Picatinny rails for maximum accessory mounting flexibility including lights, lasers, vertical grips, and backup sights. CNC machined from 6061-T6 aluminum with Type III hard coat anodized Flat Dark Earth finish.

M203 and Suppressor Compatible

The GL/SSC design accommodates both M203 grenade launcher mounting (or M320 with adapters) and suppressor use. The free-float handguard system allows for M203 attachment without making contact with the barrel, ensuring barrel harmonics and accuracy are not affected during operation. The threaded muzzle with A2 flash hider enables suppressor attachment for sound signature reduction.

SB Tactical SBA3 Pistol Stabilizing Brace

The SB Tactical SBA3 pistol stabilizing brace provides adjustable positions for different arm lengths and shooting positions. The SBA3 design improves handling and stability during firing while maintaining pistol classification, eliminating NFA registration requirements.

GRIP-N-RIP Charging Handle

The independently ambidextrous GRIP-N-RIP charging handle accommodates both left- and right-handed shooters. The body is CNC machined from 7075-T6 aluminum while handles and latch are machined from 6061-T6 aluminum. The extended latches provide positive purchase for reliable operation even with gloves.

Daniel Defense Pistol Grip

The ergonomic Daniel Defense pistol grip features integral trigger guard. The grip angle and texture are optimized for positive control and comfortable extended shooting.

7075-T6 Aluminum Receivers

The upper and lower receivers are CNC machined from 7075-T6 aluminum with matte black Type III hard coat anodized finish. This aerospace-grade aluminum provides exceptional strength-to-weight ratio and durability.

32-Round Magazine Capacity

The included 32-round polymer AR-style magazine provides substantial capacity for extended shooting sessions, training, or defensive applications. The standard capacity reduces reload frequency during high-volume shooting.

Non-NFA Pistol Configuration

As a pistol rather than Short Barreled Rifle, the GL/SSC does not require NFA registration, tax stamp, or Form 4 approval. This classification enables immediate transfer upon purchase while providing the compact dimensions and capability of the legendary GL/SSC platform.

Collectible and Functional

The GL/SSC reissue appeals to both clone enthusiasts seeking authentic SOPMOD Block II aesthetics and shooters demanding proven Daniel Defense performance. The 12.5-inch barrel with carbine gas system provides optimal balance between velocity, accuracy, and maneuverability for CQB and tactical applications. The Daniel Defense DDM4 GL/SSC delivers legendary quad rail heritage with modern enhancements—the return of an icon that defined an era of special operations rifles.
