Does what it needs to do. - BlackHawk Universal Swift Sling

Even with an Ivy League education I had trouble figuring out how to put this thing on my AR. Another reviewer called it a "Rubik's cube" accurately. However, once in place, it is a solid sling that does what it's meant to do. It doesn't have the frills of much more expensive slings, but it works well. One note: the "quick detach" option only detaches you from the sling, not the gun from the sling. Normally not an issue except if you're in active duty (armed forces, police, etc.) and need the ability to detach both yourself and the gun from the sling with a snap.
Pros: Cheap, solid construction, multiple configs
Cons: not too easy to figure out
