There are tons of video's on youtube that explain it. But pretty much you take the sling apart (Pretty easy to do) re-run the sling through the buckle slide the loop over the stock pull it tight then re-attach the keeper on the sling and run the end of the sling through the sling swivel run the sling through the keeper and clamp it closed. Or you can keep the hook on and hook that onto the rear stock sling swivel run the end of the sling through the front swivel and through the keeper and clamp closed.
I mean you could be but it’s really hard to tell because for me there was no comments when I put my comment so you might be first or I might be first nobody will ever know
