Magpul MS4 Dual QD Sling Fits AR Rifles Gen 2 Black

Product Description

The Magpul MS4 Dual QD Sling Gen 2 is a convertible rifle sling designed for AR-platform rifles that switches between one-point and two-point configurations. It uses quick-detach swivels to attach to QD sling cups on your rifle or receiver end plate.

This sling gives you flexibility when moving between shooting positions or transitioning to a sidearm. The dual-configuration design means you can adjust your carry method on the fly without removing the sling from your rifle.

The MS4 Gen 2 suits shooters who train in multiple disciplines or who need different carry options during a single range session. It works with standard QD attachment points found on many modern AR receivers, stocks, and handguards.

• SKU: MAG518-BLK
• Finish: Black
• Mount Type: Quick Detach (QD)

How the MS4 Dual QD Sling Converts Between Configurations

The MS4 uses a modular design with removable sections. One-point configuration keeps the rifle close to your body and allows rapid transitions. Two-point configuration distributes weight across your shoulder and keeps the rifle secured while you walk or use both hands for other tasks.

You switch between modes by clipping or unclipping a section of the sling. The QD swivels lock into compatible sling cups with a push-button release. Most modern AR stocks, lower receivers with QD end plates, and free-float handguards accept QD swivels.

The adjustment system lets you tighten or loosen the sling while it remains attached to your rifle. This is useful when wearing different layers of clothing or transitioning from shooting to administrative handling.

What to Know Before Buying a QD Sling for Your AR

Your rifle must have QD sling cups or sockets to use this sling. These are threaded steel inserts, usually found on the receiver end plate or integrated into the stock and handguard. If your rifle lacks QD attachment points, you will need to install compatible hardware separately.

Send us a message to confirm fit for your specific rifle setup if you are unsure whether your attachment points are compatible with QD swivels.

The Magpul MS4 Gen 2 competes with fixed two-point slings that offer simplicity and with dedicated single-point slings that prioritize close-quarters maneuverability. The MS4’s advantage is that you do not need to own two separate slings or swap hardware when your training focus changes.

Frequently Asked Questions

Q: Does the Magpul MS4 Gen 2 fit all AR-15 rifles?

A: The MS4 Gen 2 fits AR-platform rifles equipped with QD sling cups or sockets. Many modern AR stocks, receiver end plates, and handguards include QD attachment points. If your rifle does not have QD cups, you will need to install compatible mounting hardware before using this sling.

Q: What is the difference between the MS4 Gen 2 and a standard two-point sling?

A: The MS4 Gen 2 converts between one-point and two-point configurations using removable sections, while a standard two-point sling remains fixed in one mode. This lets you switch carry methods without removing the sling or changing hardware on your rifle. A fixed two-point sling is lighter and simpler but offers only one carry option.

Q: Can I use the MS4 Dual QD Sling on rifles other than ARs?

A: You can use this sling on any rifle with QD sling cups. The product name specifies AR rifles because that platform most commonly uses QD attachment points. If your bolt-action, shotgun, or other rifle has QD sockets installed, the MS4 will attach and function the same way.

Q: How do QD swivels attach and release from the sling cups?

A: QD swivels have a spring-loaded ball-detent mechanism. You push the swivel into a QD cup until it clicks and locks. To release, you press a button on the side of the swivel body, which retracts the locking balls and allows you to pull the swivel free. The system is designed for quick attachment and removal without tools.

Q: Does Magpul cover the MS4 Gen 2 under warranty?

A: Send us a message to confirm current warranty terms for this sling. Western Sport can provide the information you need or help you contact Magpul directly if a warranty claim is necessary.
