Sig MCX – HK Hook Attachment Sling Mount
The ST-MCX is a robust and unobtrusive sling mount for your MCX lower receiver. Although the ST-MCX is quick to attach, it is not quick to remove. The downfall of QD sling swivels is that they can become accidentally detached, posing a danger to yourself and others. The ST-MCX gives the operator a hard point to attach any hook style sling.
**Currently works with Gen 1 and 2 MCX only. This will not work with the SPEAR LT.**
