Product Description

The Sons of Liberty Gun Works (SOLGW) Angled M-LOK QD Sling Socket (4140ANGLEDSOCKET) is a low-profile, duty-grade sling attachment point engineered for hard-use carbines and M-LOK handguards. Designed with a 45-degree angled orientation, this mounting socket tucks the sling swivel tight against the handguard, reducing snag hazards and improving rifle ergonomics during dynamic transitions.

Precision-machined from 4140 steel and treated with an ultra-durable QPQ (Quench-Polish-Quench) salt bath nitride finish, the 4140ANGLEDSOCKET delivers extreme wear resistance, friction reduction, and deep environmental corrosion protection. The internal socket features integrated anti-rotation stops, preventing push-button quick-detach sling swivels from spinning freely and twisting two-point or single-point tactical slings into knots.

Attaching securely to any standard M-LOK rail slot with included steel hardware, the Sons of Liberty Gun Works Angled QD Socket provides a bombproof sling mounting interface built to endure severe recoil and demanding operational use.

Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits standard M-LOK rail slots on aluminum or polymer handguards. Accepts all standard 0.37" push-button Quick Detach (QD) sling swivels.

1. Perform a complete firearm safety check: drop the magazine, lock the bolt rearward, and visually inspect the chamber to verify zero live rounds are present.
2. Insert the M-LOK T-nuts and screws through the SOLGW angled QD socket body.
3. Position the T-nuts into the desired M-LOK rail slot, orienting the angled socket inward toward the top receiver plane for the sleekest profile.
4. Apply a drop of medium-strength blue threadlocker to the screw threads before tightening.
5. Tighten the hex/Torx screws while pulling outward on the mount until the T-nuts rotate 90 degrees and seat perpendicular across the inside rail lip.
6. Torque M-LOK mounting screws to 30–35 in-lbs (for aluminum handguards) and insert a push-button QD swivel to test smooth insertion and anti-rotation lockup.
