Just put a magpul CTR 6 position stock on my bushmaster predator. Looking for advise on mounting a sling. There is a slot for the sling but also a hole that I'm assuming there is some type of stud I could mount in the hole to make the sling detachable. Any thoughts on what I need. Thanks
I use the Blackhawk Heavy Duty Push Button QD Sling Swivels -
