Slings and safes do not mix.....period! So I took off all the slings. Now I have a box of slings. Some single point, push button QD, HK hook, 2-point slings, you name it, I probably have it.
Really do not know how others address the sling issue. Getting down to it, three slings would address my needs accross my AR15 platforms.
What do you do for multiple AR15s?

The adaptors give you multiple mounting options, and the upcoming attachment is working very well on shotguns as well as rifles (AK/FAL/SP-1 are a few I've been using it on) . The standard attachment works fine for carbines, and gives a few mounting options. I'm working with the prototype attachment, and I can't find anything to change at this point.
One sling for all weapons (rifle/carbine/shotgun)? I think he has got a pretty good system worked out for you.
