Turrets cant mount components, so the lack the ability to boost their performance while mechs can do so. Some components would be useless for turrets like the Vulcan, but most would be useful to improve performance.
also here are some ideas about components
1 Alter the Hawk to increase Machinegun weapon range by 5% per tier so a tier 3 Hawk would boost machinegun range by 15% for example.
2 Bring up a new component that reduces weapon minimum range by a percentage between 10% and 50% based on tier.
