Your HP seems ok, the problem comes from smoothing groups on your LP. Theres a thread on this forum somewhere that details how to properly set up your smoothing groups according to your UVs. Can you post some wireframes for the LP? What are you using for baking?
Already increased the polycount on the scope. I just left my computer but I'll send the wireframes as soon as I can. When you see them keep in mind I'm using a bevel/chamfer modifier workflow so it has lots of ngons and Tris because it's not intended for subdivision. Thanks for your feedback btw @teodar23
