Description
Overview
The Magpul RSA (Rail Sling Attachment) QD is engineered to provide a secure, low-profile forward attachment point for the Magpul MS4 Sling and other push-button QD slings on 1913 Picatinny rail systems. Manufactured from case-hardened steel with QPQ (Quench-Polish-Quench) salt bath nitride finish, the RSA QD delivers extreme resistance to wear and corrosion for long-lasting durability in harsh environments and demanding tactical applications. The robust steel construction ensures the mount can handle the dynamic stresses of sling use without failure or deformation.
The RSA QD’s design places the QD attachment point at an optimized angle for comfortable two-point sling use, positioning the sling naturally for improved weapon control and reduced neck/shoulder fatigue during extended carry. The angled orientation maintains easy push-button access for quick sling detachment when needed, while the low-profile, unobtrusive design minimizes snag points and bulk on your rifle’s rail system. Compatible with all push-button QD swivels, the RSA QD mounts securely to any MIL-STD-1913 Picatinny rail, making it ideal for AR-15, M4, M16, and other platforms with Picatinny handguards. Made in the USA with Magpul’s renowned quality and attention to detail.
