Yeah, I saw that recall and thought maybe I had a defective one at first, too, but the rollpin is there. At least, if it's the roll pin I think they're talking about. What I see is a rollpin through the endcap, running top to bottom (dustcover to pistol-grip). The wiggle is not really all that pronounced, but it's enough to be noticable and irritating.
Also, I noticed that Tromix's buttstocks have what looks like the same type of sling mount that AR collapsible stocks have. I'd been wanting to try out a 3-point sling on my 308 but wasn't sure how to attach it at the buttstock. Unless
