Magpul RSA QD Rail Sling Attachment - MAG337

A quick-detach sling point for any Picatinny rail — low-profile, over-engineered and ready in minutes.

The Magpul RSA QD (MAG337) bolts to any MIL-STD 1913 Picatinny rail section and provides a standard QD socket wherever your sling geometry needs it. Machined for a precise rail fit and finished in a hard-wearing black, it sits tight against the rail with minimal overhang — no rattle, no bulk, no snag points.

Sling attachment placement makes or breaks how a rifle carries and mounts. The RSA QD lets you put the front sling point exactly where it balances the rifle for your build and your body, rather than where the factory happened to leave a loop. Paired with any push-button QD swivel it gives positive, silent lock-up that shrugs off hard use.

Why shooters choose the RSA QD

• Adds a QD socket to any Picatinny rail — place your sling point precisely
• Low-profile machined body — tight fit, no rattle, no snags
• Positive QD lock-up — secure under load, silent on the move
