need help with texture artifacting

[chamferarea]

i have tried everything i can think of but nothing fixes it, this issue seems to effect specific models but its really annoying and ive scrapped a whole hard surfaced MK14 EBR project because of it.

things i have tried:
- making the whole low poly object out of quads
- adding more topology
- averaging normal's, playing around with projection distances

Are these artefacts on the normal map or the mesh itself?
If it's the mesh, what format do you use and where do you export from?

[chamferarea]

its on the normal map,
i also get the same effect but worse with the normals flipped when i bake the normals in 3ds max

edit (they also dont show up on the high poly object)
