Product Overview
Now shipping with our new custom Torx T20 fastener!
QDX® M-LOK Sling Mount - Our versatile take on the standard QD sling mount. Made out of 7075-T6 Aluminum with a Type 03 Hardcoat Anodizing, and weighing in at a scant 0.3oz to help minimize overall weight. By rotating the mount to allow for parallel QD insertion, we effectively reduced the QD socket footprint (with sling attached) by 16% and the sling eyelet “height” off the rail by 37%. With a mounting footprint of only 1 M-LOK slot, the QDX is also designed to fit perfectly inside the accessory cutout slot on our XOS-H Scales, available in both Machined G10 and High Temp Polymer. Additionally, the QDX allows for use with most HK-style hook attachments to provide our end users with a variety of options, and the flat forward side of the mount can even be used to brace against vertical barriers to provide a more stable shooting position.
