Sons Of Liberty Gun Works 4140 Angled QD Mount - M-LOK Steel QD Socket

The Sons of Liberty Gun Works 4140 Angled QD Mount is a steel quick-detach sling attachment point engineered for AR-platform rifles and M-LOK compatible handguards. Built from 4140 steel with QPQ corrosion treatment, this angled QD mount solves a common rigging problem: how to run a front sling attachment without sacrificing rail real estate or fighting with gear mounted at 12 o'clock. The angled design lets you route your sling cleanly beneath weapons-mounted optics and lasers, opening up your valuable 10 and 2 o'clock M-LOK slots for lights, pressure switches, and grips.

Sons of Liberty Gun Works manufactures small parts and accessories built to mil-spec tolerances, and this QD mount reflects that standard. The 4140 steel is tough enough for duty and hard-use applications, and the QPQ finish resists corrosion in the field. If you run a modern rifle with an M-LOK rail system and want a clean, low-profile sling anchor that doesn't clutter your handguard, this is a straightforward choice.

Note that this is the socket only—you'll need to source a QD swivel separately. Installation is direct: secure it to any M-LOK slot on your handguard. It's the kind of small-parts solution that pays dividends once you've sorted out your sling routing and freed up space for the rest of your setup.

Frequently Asked Questions

Will this work with my M-LOK handguard?

Yes. The Sons of Liberty Gun Works 4140 Angled QD Mount is designed for any standard M-LOK slot on AR-platform handguards.

Do I need to buy a QD swivel separately?

Yes. This product is the socket only; a QD swivel is not included and must be purchased separately.

Why would I use this instead of a standard front sling mount?

The angled design routes your sling beneath mounted optics and lasers at 12 o'clock, keeping your 10 and 2 o'clock M-LOK slots open for accessories like weapon lights or infrared illuminators.

Is the QPQ finish durable?

QPQ (Quench, Polish, Quench) treatment provides corrosion resistance suitable for field use and outdoor conditions.
