Take 2 ea used leather HK 91 slings with the fancy spring loaded clip (that sells for $15 each as an ATAS clip most places) for $10 total from CTD.
Pass the 2 free ends through the sling keepers and attach clips to either end of firearm.
You now have a multi-purpose 2.5 point sling (if that's your desire) that is about 90" long when extended for $10.
I've used this configuration for over 40 years.
I can carry "behind back w/sling across chest" and deploy the firearm to shoulder, aimed fire, in less than 1.5 seconds. Less time if slung across front of chest
Just sayin you don't need to spend $60 on a sling.
