For those who demand excellence from their rifle setup, the mounting system for a sling is more than a detail—it’s a critical piece of the overall performance puzzle. Whether you're running an AR-15 for tactical use, training, or personal defense, your sling mount should enhance—not hinder—your setup.
Enter the QDX® M-LOK Sling Mount by RailScales. Designed to replace outdated, bulky, or underperforming sling attachment options, the QDX delivers smarter, lighter, and more reliable performance across every metric. Here's why this isn’t just another QD mount—it’s the next level of quick detach sling solutions.

M-LOK QD Sling Mount Reimagined

While most M-LOK QD mounts do the job, few do it well—and fewer still bring innovation to the table. The QDX® leverages 7075-T6 aluminum, a material trusted in aerospace and defense, providing nearly twice the strength of common 6061 aluminum and vastly outperforming budget polymer mounts. Combined with Type 03 hardcoat anodizing for advanced corrosion resistance, the QDX is built to withstand abuse in any environment.

• Material: 7075-T6 aluminum
• Finish: Type 03 hardcoat anodized
• Mounting System: M-LOK
• Weight: Ultra-lightweight without compromising strength

Reduced Rail Footprint and Enhanced Integration

Unlike standard QD sling mounts that create unnecessary bulk or interfere with neighboring AR accessories, the QDX® was engineered with streamlining and modularity in mind:

• Parallel QD Insertion: This design innovation lowers the sling height off the rail by 37% and reduces overall mount footprint by 16%, making it an excellent fit for slim-profile rifles or handguards.
• Low-Profile Design: Sits flush with the rail, eliminating sharp edges or snag points common in raised QD mounts.
• Mounting Efficiency: Unlike conventional mounts that block M-LOK slots, the QDX’s compact profile opens up more usable real estate on the handguard for additional accessories such as light mounts or handstops.

Better Functionality, Lower Weight

When every ounce matters, especially on tactical rifles or SBR builds, the QDX makes a measurable difference. Compared to commonly used budget sling mounts:

• The QDX is up to 35% lighter than most steel-based QD mounts.
• The anti-rotation feature keeps slings from twisting or torquing during transitions.
• Offers enhanced sling placement flexibility when paired with XOS-H™ Scales, enabling seamless ergonomic integration.

QDX vs. Budget Sling Mounts: Not Even Close

Feature	QDX M-LOK Sling Mount	Common Budget Mount
Material	7075-T6 Aluminum	Polymer or 6061-T6
Anodizing	Type 03 Hardcoat	Standard Anodizing
Sling Height Offset	Reduced by 37%	Raised off rail
Mounting Footprint	Reduced by 16%	Takes up multiple M-LOK slots
Anti-Rotation	Yes	Often lacking
Compatibilty	Pairs with XOS-H™ Panels	Limited
Weight	Ultra-Light	Often heavier

The QDX isn’t just about attachment—it’s about optimization. From better transitions to improved balance and less interference, it adds performance rather than bulk.

Why QDX® Beats Standard QD Sling Mounts

In short, the QDX® M-LOK Sling Mount from RailScales:

• Reduces snag points


Thanks to its ultra-low-profile design and recessed QD cup orientation, the QDX minimizes sling height and eliminates protrusions that commonly catch on gear, clothing, or barricades—critical in high-mobility or CQB environments.

• Preserves M-LOK slot real estate


The QDX’s streamlined footprint uses fewer M-LOK slots than traditional mounts, freeing up valuable handguard space for lights, foregrips, or other mission-essential accessories without crowding your rail.

• Improves accessory stacking


Because it sits tighter to the rail and mounts with parallel insertion, the QDX integrates more cleanly with adjacent accessories, making it ideal for shooters running XOS-H® panels, weapon lights, or pressure switches in confined spaces.

• Strengthens overall rifle control

A stable sling point allows for better rifle retention and transitions, especially when running a two-point sling. This directly translates to smoother target acquisition, improved reloads, and tighter control in dynamic movements.

• Delivers a rugged, featherweight footprint


Machined from aerospace-grade 7075-T6 aluminum and hardcoat anodized to Type 03 spec, the QDX offers the durability of duty-grade gear at just a fraction of the weight—essential for lightweight rifle builds where every ounce matters.

FAQ: QDX® M-LOK Sling Mount

Q: What material is the QDX made from?

A: The QDX is machined from 7075-T6 aluminum, known for its strength and performance in aerospace and military applications.

Q: How does it compare to standard QD sling mounts?

A: The QDX reduces rail footprint by 16% and sling height by 37% compared to traditional mounts. It’s also lighter, stronger, and built with better integration in mind.

Q: Is this compatible with any sling swivel?

A: Yes, the QDX is compatible with most standard push-button QD sling swivels on the market.

Q: Will this fit on my current M-LOK rail?

A: Absolutely. The QDX is designed for any standard M-LOK slot, and its compact design ensures minimal interference with other mounted accessories.

Q: Can I use this on both sides of my rifle?

A: Yes. The QDX’s low-profile geometry and universal M-LOK compatibility make it suitable for mounting on either side of the handguard.
