Daniel Defense® Rail Mount QD Swivel Attachment Point – Patented Rock & Lock™ 1913 Picatinny Clamp – Includes Heavy-Duty 1.25" Push-Button QD Sling Swivel – Limited Rotation – Matte Black – 03-021-30029
Product Description
The Daniel Defense® Rail Mount QD Swivel Attachment Point (03-021-30029) represents an elite, battle-proven milestone in multi-mission tactical sling logistics, structural weapon retention ergonomics, and low-profile gear attachment staging, masterfully engineered and manufactured in Black Creek, Georgia, USA. Purpose-built to serve as the ultimate high-efficiency retention anchor for hard-use carbines, this compact interface module completely modernizes how professional operators sling their weapon platforms. While traditional thread-on or loose sling loops clutter valuable handguard space and slide erratically under dynamic movement, the Daniel Defense system mounts flush anywhere along your rail. This premium hardware asset (852548002141) establishes an indispensable foundation to optimize rifle security, secure clean cross-body transition loops, and maintain absolute structural uniformity under hard field tracking operations.
The foundational design triumph of this streamlined mounting hub relies on Daniel Defense's patented Rock & Lock™ one-piece mounting infrastructure. Moving past multi-piece clamps that require complex armorer alignment drills or suffer catastrophic stress fractures from rough handling, this single-piece aircraft billet block hooks directly onto any standard MIL-STD 1913 Picatinny track. A single high-tensile steel cross-bolt applies continuous, even clamping torque across the rail channel, achieving an ultra-tight, absolute zero-play lockup configuration that withstands punishing combat environments. Precision CNC-machined from 6061-T6 structural aluminum alloy and treated with a Military Specification Type III Hardcoat Anodized finish, the mount shrugs off invasive moisture, chemical solvent wear, and abrasive trail grit with flawless ease.
The true tactical victory of this American-engineered masterpiece lies within its integrated limited-rotation receiver geometry. By integrating physical internal stopping nodes within the QD socket walls, the mount permits a full range of tracking motion while successfully halting the quick-detach swivel from spinning into infinite full rotations. This structural constraint entirely blocks your 1.25-inch tactical sling from twisting, binding up, or knotting during high-tempo workspace manipulation. Shipping straight from the factory complete with a matching, heavy-duty Push-Button Quick Detach (QD) Sling Swivel out-of-the-box, this ultra-lightweight 1.5-ounce system matrix grants you complete administrative and operational authority over your weapon staging ecosystem.
Includes: (1) Authentic Daniel Defense Rock & Lock Picatinny Rail Mount QD Attachment Base (Matte Black Type III Hardcoat Anodized), (1) Heavy-Duty Push-Button 1.25" Quick Detach Sling Swivel Loop, (1) Integrated Steel Locking Cross-Bolt Assembly, Packed in Original Branded Factory Sealed Retail Staging Packaging.
*Administrative Mounting & Sling Safety Guidance: The Daniel Defense 03-021-30029 sling attachment point is calibrated exclusively for standard MIL-STD 1913 Picatinny rail tracks; it will not interface directly with M-LOK or KeyMod slots without a standalone rail section adapter. When installing the Rock & Lock base onto your upper receiver or handguard rail, torque the mounting hardware down firmly using a high-quality hex wrench; do not over-torque to avoid stripping the fastener threads. Always test the integrity of your sling system by pushing the central button, seating the swivel fully into the socket, and giving a sharp outward tug to confirm complete ball-bearing lock engagement. Prior to executing workbench installation, visually and physically verify that your host firearm frame is entirely unloaded, cleared, and safe.
