Black lines appearing on blueprint actor from lighting

Hey all,
I am currently having an issue with my scene where I am having a hard black line being drawn on my blueprint actor from the lighting. The actor contains 3 sk meshes that are within the blueprint to drive blendshape/morphs. I have attached 4 images from the scene where you can see that the lighting isnt coming from the texture, and is coming from the lighting. Any tips or solutions would be much appreicated.

So I am unsure if this is the issue, but it seems like the bounding box of the object might be causing the lighting issue. It seems like part of the gun is outside of its bounding box which is causing weird issues with the lighting.
