Rankin Industries MLOK QD Sling Mount

Product Description

The Rankin Industries MLOK QD Sling Mount is a quick-detach sling attachment point that installs into any M-LOK accessory slot on your rifle handguard. It accepts standard push-button QD sling swivels and lets you position your sling attachment exactly where you need it.

M-LOK handguards allow modular placement of accessories without the weight or bulk of continuous rails. This mount gives you a low-profile sling attachment that sits flush when installed and rotates freely under load to prevent sling twist.

Quick-detach sling hardware has become the standard for two-point rifle slings because it allows tool-free attachment and removal in seconds. The QD swivel locks into the mount with a spring-loaded ball detent that holds securely during use but releases instantly when you press the button.

How M-LOK QD Mounts Install

M-LOK mounting hardware uses a recoil lug and T-nut system that locks into the handguard slot. You slide the mount into the slot from the front or rear of the handguard, align it at the angle you want, then tighten the fastener from the exterior side. The recoil lug engages the internal slot geometry to prevent rotation under load.

Most shooters place QD mounts at the three o’clock or nine o’clock positions near the front of the handguard for two-point slings. Mounting further forward shifts weight toward the muzzle and changes how the rifle hangs across your body. Some prefer a rear mount on the receiver extension for single-point configurations.

QD vs Fixed Loop Sling Mounts

Quick-detach mounts let you remove your sling completely in seconds without tools. Fixed loop mounts require you to thread the sling webbing through during installation, which means the sling stays attached unless you disassemble the mount or cut the webbing.

QD systems add a small amount of weight compared to a simple loop, but the convenience matters when switching slings between rifles or removing a sling for storage or cleaning. The swivel itself also rotates to prevent the sling from binding as you transition shoulders or move through barriers.

What to Confirm Before Installing

Verify that your handguard uses M-LOK slots, not KeyMod or Picatinny rails. M-LOK slots are elongated ovals with internal recoil lugs, while KeyMod uses keyhole-shaped cutouts. Picatinny rails have raised cross-slots and require a different mount style entirely.

Check the handguard wall thickness and internal clearance if you are installing near the gas block or inside components. Some ultra-lightweight handguards have thin walls that limit fastener engagement. If you have questions about fit on your specific handguard, send us a message and we can walk through the installation.

Frequently Asked Questions

Q: What handguards is the Rankin Industries MLOK QD Sling Mount compatible with?

A: The Rankin Industries MLOK QD Sling Mount fits any handguard with M-LOK accessory slots. M-LOK is a standardized mounting system used across hundreds of handguard models from manufacturers including Magpul, BCM, Midwest Industries, Aero Precision, and many others. It will not fit KeyMod or Picatinny rail systems.

Q: Does this mount work with all QD sling swivels?

A: Yes, this mount accepts all standard quick-detach sling swivels that use the push-button ball-detent locking system. QD sling hardware follows a common specification, so swivels from Magpul, Blue Force Gear, Viking Tactics, and other manufacturers will lock into this mount securely.

Q: Can I rotate the QD mount after installation?

A: Most M-LOK QD mounts allow you to set the rotation angle during installation before final tightening. Once the fastener is torqued down, the mount position is fixed to the handguard. The QD swivel itself rotates freely inside the mount to prevent sling twist, but the mount body stays locked in place.

Q: How many mounting screws or T-nuts does this sling mount require?

A: Send us a message to confirm the hardware included with the Rankin Industries MLOK QD Sling Mount. M-LOK mounts typically use one or two T-nuts depending on the mount length and load requirements, but confirming the specific kit contents ensures you have the right tools ready for installation.

Q: Where should I position a QD sling mount on my rifle handguard?

A: Most shooters install QD sling mounts at the three o’clock or nine o’clock positions on the handguard, typically one-third to halfway forward from the receiver. This placement balances the rifle well for two-point slings and keeps the mount clear of your support hand grip. Front-heavy or muzzle-device-heavy rifles benefit from mounts positioned further back to shift the balance point rearward when slung.
