Magpul RSA Side Mount for QD Swivel on Picatinny/Weaver

Magpul RSA QD is a front side mount for a quick-detach (QD) swivel, designed for secure attachment of two-point slings. It mounts on a standard Weaver/Picatinny rail (MIL-STD 1913 Picatinny or STANAG 4694) and allows the swivel to be positioned on the handguard to the left or right without increasing its bulk.

The construction is made of stainless steel with a matte black finish, ensuring corrosion resistance and minimal glare. Weighing only 37 g, the mount can withstand loads exceeding 136 kg, guaranteeing reliability in field conditions and during active weapon use.

Advantages and Purpose

The RSA QD is designed for quick attachment of a QD swivel to rail platforms when a low-profile handguard installation is required. It is suitable for users who value compactness, ease of installation, and the ability to choose the mounting position (left or right). Thanks to its compatibility with MIL-STD 1913 / STANAG 4694, the mount easily integrates with most modern tactical rails.
