Magpul MS4 Dual QD Sling GEN2 MAG518 Convertible 1/2-Point Rifle Sling - Multiple Colors Available

Magpul MS4 Dual QD Sling GEN2 MAG518 Convertible Tactical Rifle Sling Multiple Colors Available

Product Description

The Magpul® MS4® Dual QD Sling GEN2 (Model MAG518) is a mission-adaptable, convertible one-point and two-point tactical weapon sling engineered for rapid transition between close-quarters shoulder-to-shoulder manipulation and stabilized two-point retention. Offered across four operational colorways—Black (MAG518-BLK), Stealth Gray (MAG518-GRY), Coyote Brown (MAG518-COY), and Ranger Green (MAG518-RGR)—the GEN2 architecture upgrades the platform with Magpul's low-profile MS1® quick-adjust slider and extended overall webbing length to accommodate full plate carriers, chest rigs, and cold-weather layering.

Built in the U.S.A. to strict Berry Amendment standards, the MS4 Dual QD GEN2 utilizes custom-milled 1.25-inch wide nylon webbing engineered for high tensile strength and anti-chafe comfort against the neck and shoulder. All colored webbing variants (Stealth Gray, Coyote Brown, and Ranger Green) receive specialized Near Infrared (NIR) treatment to minimize night-vision signature. Critical load-bearing hardware features heavy-duty push-button Quick Disconnect swivels paired with a precision-cast steel QD D-ring treated in a QPQ salt-bath nitride (Melonite) finish, delivering superior resistance against salt spray, carbon fouling, and abrasive wear.

The streamlined MS1® polymer slider eliminates loose webbing tails, snag hazards, and bulky buckles while providing 10 inches of smooth, single-handed tension adjustment in two-point mode. With 48 to 60 inches of nominal length plus ± 5 inches of gross sizing travel, operators can instantaneously unclip the forward QD swivel and lock it into the steel D-ring to convert from a cinched two-point patrol carry into an agile single-point CQB configuration without removing the sling from the body.

*Armorer Bench Notes & Real-World Staging Guidance:*

Fitment Matrix: Compatible with AR-15, M4, AR-10, SCAR, AK, and tactical shotgun platforms outfitted with standard Mil-Spec push-button QD sling swivel sockets (such as the Magpul ASAP® QD end plate, M-LOK® QD Sling Mount, or RSA® QD rail mount). CRITICAL WARNING: Do NOT attempt to run this sling on fixed wire loops, HK hooks, or un-chamfered aftermarket aluminum handguard sockets that lack a hardened steel locking race, as soft aluminum sockets can wear and allow accidental swivel detachment under recoil or dynamic movement.

1. Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty before attaching or sizing any sling hardware.
2. Select your desired color variant and verify that both push-button QD swivels and the QPQ nitride steel D-ring actuate smoothly with positive spring return.
3. Size the base webbing length through the tri-glide buckles with your primary armor or range attire worn, leaving the MS1® slider in the mid-to-rear position for maximum cinch range.
4. Insert the rear QD swivel into the receiver end plate or stock socket and the forward QD swivel into the handguard socket, then pull sharply on the webbing away from each socket to confirm full ball-bearing lockup.
5. Conduct dry-fire shoulder transitions and one-point to two-point D-ring conversions to verify zero interference with charging handles, ejection ports, or optic controls prior to live-fire staging.
