Sons of Liberty Gun Works QD Socket Features The Sons of Liberty Gun Works QD Socket is machined from 4140 steel and finished with a QPQ treatment a process that improves wear resistance and corrosion protection compared to a standard black oxide finish. Its angled design lets shooters position a front sling attachment point tightly beneath accessories mounted at the 12 o clock position such as a laser or weapon light without the sling point getting in the way. By using the 10 and 2 o clock M-LOK slots instead of a straight down mount the socket frees up valuable rail space for other accessories. The anti rotation design keeps the socket securely fixed in place once installed preventing it from shifting under use. This QD socket is built for direct installation onto any M-LOK compatible handguard or rail segment found on an AR-15 or similar platform. Sons of Liberty Gun Works builds its small parts to fit most mil spec firearms making this socket broadly compatible with common AR-15 builds. Shooters should note that a QD swivel is not included with this socket and must be purchased separately to complete the sling attachment point. For AR-15 owners looking to optimize their M-LOK rail space while adding a secure front sling mount the Sons of Liberty Gun Works QD Socket is available for sale at GrabAGun.
