Seriously good idea on the sling keeper...I'd buy a couple too.
Good idea. However I'm curious if the rifle is going to want to still move and bounce back and fourth without a solid attachment point on the stock. Similar to the MR setup.
I haven't used either just curious?
I'll see what I can dig up. To answer an old question no it's not locked on your shoulder rock solid. Don't think of it as an alternative to a gun bearer, think of it as just something that keeps the sling on your shoulder while wearing a pack
