Magpul Industries Quick Detach Sling Swivel Black

Product Description

The Magpul Industries Quick Detach Sling Swivel Black (MAG540) is a QD-style attachment point that installs into standard quick detach sockets for rapid sling mounting and removal. This swivel features a black finish and uses the push-button quick detach mount type found on modern rifles and carbines.

Quick detach swivels give you the ability to attach or remove a sling in seconds without tools. The push-button release locks into any mil-spec QD socket, creating a secure connection until you press the release.

This type of swivel works with two-point slings that terminate in a QD-compatible loop or attachment point. Most modern tactical slings are built around the QD standard because it eliminates the need for permanent hardware.

How QD Sling Swivels Work

A quick detach swivel has a spring-loaded button on one end and a hardened steel ball-bearing locking mechanism inside. When you push the swivel into a QD socket, the bearings engage and lock it in place. Pressing the button retracts the bearings so you can pull the swivel free.

The advantage over traditional loop swivels is speed and versatility. You can move a sling between rifles in seconds, or remove it entirely when it is not needed. QD sockets are standard on most modern AR-15 handguards, receiver end plates, and stock assemblies.

What to Know Before Buying a QD Swivel

You need a QD socket on your rifle to use this swivel. These sockets are threaded holes roughly 0.25 inches in diameter, usually found on the receiver end plate, stock, or handguard. If your rifle does not have a factory QD socket, aftermarket mounts and end plates are available.

Some slings come with built-in QD swivels already attached. Others use a loop or webbing end that requires a separate swivel like this one. Check your sling hardware before ordering to confirm you need a standalone swivel.

Most QD swivels rotate freely to prevent sling twist. Call 817-393-4000 to confirm rotation and compatibility details for the MAG540.

Frequently Asked Questions

Q: Will the Magpul MAG540 QD swivel fit my AR-15?

A: It will fit any AR-15 or other rifle that has a standard quick detach socket installed. QD sockets are common on modern rifles, but if your rifle does not have one, you will need to add an aftermarket QD-compatible end plate, stock, or handguard mount. Call 817-393-4000 to confirm compatibility with your specific setup.

Q: What is the difference between QD and traditional loop swivels?

A: QD swivels use a push-button release and lock into a threaded socket, allowing tool-free attachment and removal in seconds. Traditional loop swivels thread through a sling loop and are held in place by a screw or pin, making them slower to install or remove but compatible with older rifle designs that lack QD sockets.

Q: Can I use this swivel with a single-point sling?

A: Yes, as long as the single-point sling has a loop or attachment point designed to accept a QD swivel. Most modern single-point and two-point slings are built to work with QD hardware, but verify that your sling is QD-compatible before ordering.

Q: Does the MAG540 swivel rotate to prevent sling twist?

A: Call 817-393-4000 to confirm the rotation feature and other mechanical details for the MAG540. Rotation is common on QD swivels to keep the sling from binding, but we recommend verifying the specification before purchase.

Q: How do I install a QD sling swivel?

A: Press the button on the swivel and push the swivel body straight into the QD socket until you hear or feel it click into place. Tug on the swivel to confirm it is locked. To remove, press the button and pull the swivel straight out of the socket. No tools are required.

Q: Where is Western Sport located and how do I order?
