Ok I’m checking out the file now! Pistol_Sights_Adjust_Dial_LOw and Pistol_sights_Adjust_Low need sharp edges, but that’s not the main thing. What you need is cage objects for the rest of your low poly pieces! Currently your low poly and high poly are directly on top of each other, which will cause all sorts of issues. To make this as painless as possible, try combining all of the pieces that are not touching each other so that you have less low poly and cage objects to deal with. Hope that helps!
