I need to get a sling put on my shotgun in the near future. I already have an Uncle Mike's Super sling (quick detatch) that needs to be put to use but I'm not sure how to mount a stud on the front part of the gun. I have a Mossberg 500 w/ a 20in barrel. Mounting the rear stud won't be a problem but I need some ideas for the front stud... Thanks!
