Headscratchers / Mobile Suit Gundam Narrative

• The Silver Bullet Suppressor. Because the recoil of the Beam Magnum causes the systems of mobile suits outside of the RX-0 series to malfunction, it circumvents this by being able to swap out its arm for all five shots. Ok, that's fine and dandy, but if they have a fancy system to swap out arms and the materials to build said system and extra arms, why don't they just use their resources to reinforce the right arm to keep it from malfunctioning in the first place?
  • Possibly because the stock Silver Bullet, thanks to its ancestry in the Doven Wolf, has detachable arms as a stock feature, so the Suppressor needed practically no modifications to that end.
