Hooks are old school and have been replaced by more modern solutions.

QD sockets are found pre-installed on some stocks (like the Victor Titan), or can be added to any wood stock like I did on this Boyd's Pro Varmint. This emulates the placement of those on the Victor stock and they're great.

But what I've used the most over the years is the basic quick detach sling swivels like this.

Both of these solutions are more modern, easier, and faster than the hooks from yesteryear.
