in its current form its a non destructive setup but i will be extending the rails over the existing rear sight block and lowering the rail profile. because having a riser mount for optics to see over the fixed ironsights looks ugly and also because i dont really care about the MP5s
another reason for this is... wearing a face mask and using the guns sights is extremely uncomfortable. so when i have the tools to create the custom diopter and front sight it will be added on this MP5
