You are correct sir! I went back and found the YouTube video I had seen with a similar slightly canted forward grip and it was an actual SBR it was mounted on. Definitely remove it and the pic, like you said I'm sure it's an honest mistake. Now I'm curious , at what angle to the centerline of the bore does the ATF view as being OK on a pistol? I myself SBR'ed my Scorpion years ago but I'm curious.
