The Magpul RSA is a steel fixed-loop sling mount that clamps to any MIL-STD 1913 Picatinny rail section.
The original rail sling attachment — a steel fixed-loop sling point built to outlast hard use.
The Magpul RSA (MAG502) is a rugged, steel-bodied sling attachment that clamps to any MIL-STD 1913 Picatinny rail and presents a fixed loop compatible with both snap-hook slings and clip-in swivels, including the Magpul Paraclip. Where polymer sling points flex and aluminium loops wear oval, the RSA's steel construction takes years of loaded carry without complaint.
Its genius is its simplicity: no bearings, no buttons, nothing to fail. Mount it to a top, side or lower rail section to set the sling angle that suits your carry — the loop's geometry keeps webbing and hooks captive and quiet. For duty rifles, trainers and any gun that gets slung more than it gets shot, the RSA is the fit-and-forget answer.
Clamps to any 1913 Picatinny rail section, so a handguard rail or a short rail panel is all it needs — leave enough clear rail for the clamp body once your lights and covers are accounted for. An M-LOK-only handguard would need a rail section adding first. It takes looped slings, snap hooks and QD swivel adapters, and pairs naturally with the Magpul MS3 GEN2's Paraclip. Seat it against a rail slot so recoil cannot walk it forward.

It clamps to any 1913 Picatinny rail section, so a handguard rail or a short rail panel is all it needs. Leave enough clear rail for the clamp body once your lights and covers are accounted for. It is a rail attachment only, so an M-LOK-only handguard would need a rail section adding first.
The RSA is a fixed-loop attachment, so it will take looped slings, snap hooks and QD swivel adapters. That makes it a useful choice if you run more than one sling with different end hardware. If you want a true push-button socket instead, the <a href="/products/magpul-rsa-qd-rail-sling-attachment-qd-mag337">RSA QD version</a> is the one to look at.
The MAG502 is steel, so it is intended to take the loads a sling puts through a single point. It clamps on with ordinary hand tools; seat it against a rail slot so recoil cannot walk it forward, and check the fastener again after a few outings. There is nothing to service beyond keeping it clean and the screw tight.
Just a sling that can attach to a fixed loop, or a snap hook or adapter if your sling ends in a QD swivel. It is supplied in a single finish, so the decision is mainly where on the rail to mount it. Options for the sling itself are in <a href="/collections/rifle-slings-sling-mounts">rifle slings and sling mounts</a>.
