【All-Steel Construction. QPQ Salt Bath Nitride Finish. Optimized Angled Position. Compatible with 1913 Picatinny Rails. Made in USA.】

The Magpul RSA® QD (Rail Sling Attachment QD) provides a forward attachment point for the Magpul MS4® Sling and other push-button QD swivels. Designed to mount on MIL-STD 1913 Picatinny rails, it offers a professional-grade solution for shooters who need to add a secure QD socket to their rail-equipped platforms.

Key Features & Tactical Benefits:

• 🛡️ Battle-Hardened Steel: Machined from solid steel and treated with a QPQ salt bath nitride finish. This ensures maximum resistance to wear and environmental corrosion, providing a lifetime of reliable service.
• 📐 Strategic Placement: The RSA QD's geometry is designed to position the attachment point close to the rail, maintaining a low profile. This prevents the sling hardware from snagging on gear or obscuring the operator's sight picture.
• ⚡ Seamless Transitions: The deep-seat QD socket allows for rapid attachment and detachment of the sling. Its smooth internal finish ensures your QD swivel can rotate freely, preventing the sling from bunching or twisting under movement.
• 🏗️ Extreme Duty Performance: Unlike aluminum alternatives, the all-steel RSA QD is built to withstand the heavy recoil and dynamic stress of professional operational use.
• 🎯 MS4 & QDM Optimized: While universal for all QD swivels, it is the factory-recommended forward mount for the Magpul MS4 Dual QD Sling and QDM hardware.
• Proudly Made in the USA: Manufactured to Magpul's exacting standards for fit and finish.
