Since the begining of the developpement, lazers always have been weird when looked through a scope. They get bigger and bigger depending on the zoom level you have. Here's an example :
The size of the dot in the screenshot above is proportionally the size of a human head, if not even bigger. It's not right. This is only with a 2x scope. It looks really weird and annoying with a 4x - 7x scope...
Can it be fixed ? I don't recall Insurgency 2 having that issue.
