Yeah, that's an occasional issue with new hunter chest pieces. For whatever reason that particular torso body mesh doesn't play nice with that particular leggings body mesh. (pretty sure you'll see the same issue with the optimacy leggings ornament too). With how often it happens you'd think Bungie would have fixed the two base body meshes so they're not constantly having seam issues. Rather than having to repeatedly go back to fix the armor pieces afterwards.
