Magpul RSA QD Rail Sling Attachment (MAG337, Black) — a low-profile, case-hardened steel QD sling socket that clamps to any 1913 Picatinny rail, with an anti-rotation socket angled for two-point slings.
$88.95
Available on back-order
The Magpul RSA QD (Rail Sling Attachment QD) adds a push-button QD sling socket to any MIL-STD-1913 Picatinny rail. Its anti-rotation socket stops the swivel twisting while still allowing a useful range of movement, and the socket angle is optimised for two-point slings. The low-profile body keeps clear of optics and does not interfere with operating the rifle. It is made in the USA from precision-cast, case-hardened steel with a QPQ salt-bath nitride finish for corrosion and wear resistance, and accepts standard push-button QD swivels including the Magpul QDM and QD Sling Swivel (MAG540).
What does the Magpul RSA QD fit?
Any MIL-STD-1913 Picatinny rail section, top, side or bottom.
Does it come with a QD swivel?
No — the RSA QD is the socket only. Pair it with a push-button QD swivel such as the Magpul QD Sling Swivel (MAG540) or QDM.
What is the difference between the RSA and the RSA QD?
The RSA (MAG502) is a loop for clip-on Paraclip-style slings; the RSA QD (MAG337) is a push-button QD socket.
