Each FCS has a set box size/shape which is then modified based on your weapon lock types. WS>ST>SP>ND as far as box size goes. Each FCS if affected in different ways by lock types. An example is that F69 retains a bigger box with SP weapons while Limpet works better with ST weapons even though both are WS type FCS's. When you have dual wield weapons the FCS averages the single wield box sizes each weapon would give you then uses the parallel sight stat to reduce the size. F73H has a parallel sight of 90 so if you equip ST+WS you get a box size that is 90% of those 2 lock types averaged. Range works in the same way except WS is the shortest range up to ND which has the highest range. The range stat on weapons themselves have no affect on how far you can actually lock on, just how far the round will travel before disappearing.
In NX-LR it is very common to equip WS weapons on the left to increase the box size. It makes using SP and ND weapons a lot easier.

Fuck protoss.
