User blog comment:Didikins/How I Thik AW Weapons Should be Revised/@comment-5189447-20141123100837/@comment-3967954-20141123161336

Those weapons do have their own unique models; it's the animations that have been reused. You don't know what "reskinned" means, either - a reskin is when you lift a model and give it new textures, kind of like what they did with the ARX-160. The Pytaek and MP-11 both have original models made by Sledgehammer which use the animation sets of the LSAT and CBJ-MS, respectively.
