I like the sling set ups where you can sling it in front of you like an AR. Plus this allows you to still use American or African carry. I have used the padded Vickers sling in classes with Awerbuck and Haught. Easy to sling that way with the Magpul stock, you just need a sling plate adapter for the forend. I'm sure GG&G has something.
I don't like the sling plate that goes between the receiver and stock. When you go to sling it has a tendency to hang at more of an angle as opposed to muzzle straight down, and it's easier to inadvertently laser peoples feet.
