Just got my sling. Cheated a little on a tour at work and somehow ended up at my mailbox, which oddly enough had a package from TAG in it. First look indicates the sling is great, and everything that you've heard. I ordered the coyote brown with an extra attachment. Later today when I have time to switch my receiver plate out with the DD ambi plate from Jason and pick up my 590 I'll start trying out the sling on the shottie and the M4, as well as an 870 top folder. I got the extra attachment as a way to use one sling on three (at least) weapons, but I can already see that I'll probably be ordering from Jason again, at least to the tune of one more sling.
I've got a few points in my head right now, but I'll post again after I have a chance to work with the sling and let everybody know what I think
Jason, again your customer service is beyond comparison IME.
