About the Magpul QD Sling Swivel
The Magpul QD Sling Swivel is a machined heat-treated steel push-button quick-detach swivel that mates with every standard MIL-STD 1/8" QD sling socket on the market. Pull the button, slide the swivel into the socket, release — the locking detents seat with a positive click and the swivel spins freely under load. One-handed attach and detach.
It works with the matching Magpul M-LOK QD Sling Mount, with Magpul stocks pre-cut for QD (CTR, STR, ACS, MOE SL-K), and with any third-party QD-equipped rail, endplate, or stock socket from BCM, Daniel Defense, GG&G, Vickers, Mission First Tactical, etc. The swivel head accepts both 1" and 1.25" webbing, so it pairs with virtually any 2-point or single-point sling. Two of these is the standard kit for a 2-point setup.

Frequently Asked Questions
Will this fit my sling mount?
Yes if it has a MIL-STD 1/8" QD socket. That covers Magpul (M-LOK QD Mount, CTR/STR/ACS/MOE SL-K stocks), BCM, Daniel Defense, GG&G, Vickers Tactical, Mission First Tactical, and virtually every modern manufacturer.
Is this stronger than a polymer swivel?
Yes — all-steel construction has a much higher pull-strength rating. Strongly recommended for heavier rifles (AR-10, precision rifles) or any hard-use application.
Do I need two for a 2-point sling?
Yes — a 2-point sling needs a QD swivel on each end (one at the buttstock socket, one at a handguard or endplate mount). This listing includes one swivel per pack.
Does it work with both 1" and 1.25" slings?
Yes — the loop is dimensioned for both widths, so it pairs with Magpul MS1/MS3/MS4, Blue Force Gear Vickers, Ferro Slingster, Edgar Sherman, and virtually every standard tactical sling.
Will it rattle or wear loose over time?
No — the steel detent and tight socket tolerances stay quiet and tight through normal duty cycles. Backed by Magpul's lifetime limited warranty.
