Weapon perks

Your weapon gains experience as you kill NPCs or use Upgrade Parts on it. Upon gaining enough experience it will unlock new perks and their color will change.
First three perks on tier 3 gear are always predefined. Some tier 4 items have random perks even on first three levels.
Fourth perk you are able to chose by dialog window once you unlock it. Exception to this is when you level your weapon by Upgrade Parts then perk will be random.
Fifth perk and legendary perks are always random.
Every weapon can be upgraded by Roger to gain one additional perk.
