I'd like to see "Jury-rigged" changed a bit.
Firstly, I'd suggest removing the ability to reduce the Advantage cost on triggering a weapon's quality, because it makes Auto-fire broken again. I'm fine with the +1 damage and reduced Critical cost, but reducing Auto=fire back to just 1 Advantage per activation makes this a very powerful option.
Also, the text doesn't cover what happens when the weapon or armor in question is lost. Assuming the bonus does not automatically convey to another of the character's weapons or pieces of armor, then the character has in effect lost XP equal to the cost of the talent. Is this what the designers' intend?
