15%. Precisely, 15% for each step of upgrade when comparing to the basic requirement of the weapon. For some examples, Grenade Launcher can get a maximum of 75% when upgrading Heavy 1 to 6, Laser Rapier can get a max of 30% when upgrading Energy 4 to 6, Wrench can get a max of 90% when upgrading Standard from 0 to 6 (since that's the only weapon that works without a minimum weapon requirement and IS of the Standard type), and weapons that require a Weapons Skills of 6 (like the Assault Rifle) logically do not have any bonus damage.
