Not a bad sling - a little bulky - BlackHawk SWIFT Sling Collapsible Stock M16/AR15- Left 70GS00DE-LEFT

This is a nice, durable sling that will retain a weapon securely. After adjustment it is very easy to bring the weapon on line quickly. The construction is excellent - the webbing is heavier than many other slings I've seen/used, and it's much more durable. It has a couple of nice features too; one is a buckle quick-release so you can pickle your rig in a hurry (although dropping your primary weapon is obviously a pretty desperate measure). The other feature I like is a latch to release the loop in three-point mode, giving some slack and allowing you to transition from a right-hand to left-hand shooting quickly (usually not very easy in a 3-point sling). The biggest drawback to this sling is that all the buckles make it a little bulky, and possibly noisy - they keep rattling on the weapon if there's any slack while you're moving around. I solved that issue with some duct tape.
Pros: Good construction; durability; features
Cons: Bulky for a sling; buckles can be noisy
