Light durable sling swivels uncle mike's - Uncle Mike's QD Super Swivel w/Tri-Lock

These lock and screw down. They are very durable and can be used on just about any gun, great for hunting rifles in my opinion.
Pros: Lockable, durable, lighter than some competitors
Cons: locking mechanism can take time to get undone
