Single point qd sling vism - VISM Qd Mount Single Point Bungee Sling

Purchased 5 of these slings. The material the sling is made of is up to the task. However, the quick detach portion of the sling is quite simply, junk. The QD hardware is not at all up to anything more than looks. These slings were paired up with MCarbo QD attachments for the Kel Tec Sub2000 9mm Gen2 Carbine. After only 1 day of use at the range, 2 of the 5 are unserviceable and all 5 slings are incapable of remaining attached to the carbine during the discharge of the weapon. The recoil of the weapon causes the release of the QD. One of the metal sling loops pulled apart during transition from right to left shoulder drills. Would never purchase these again. Very, very dissatisfied.
