If you take the venerable Blue Force Gear Vickers Combat Applications Sling (VCAS) and put it on a diet, you would probably end up with something pretty close to the new Vickers ONE Sling.
The Vickers ONE Sling (VOS) shares many of the same features with the classic VCAS. It has Blue Force Gear’s excellent webbing, their extremely durable custom hardware, and the quick adjust slider with contrasting pull tab. However, unlike the standard VCAS, this slimmed down version has 1″ webbing (the VCAS has 1.25″ webbing). This makes the VOS more easily compatible with some firearms like the CZ Scorpion Evo or others with integral 1″ sling loops. It also makes for an extremely lightweight sling for applications that do not require a wider or padded sling.
