Here's what it could be:

1) Vigilante mods: the Vigilante mods has a special effect that enchantes your critical chance. This means that your weapon could deal orange or red crits.

2) Adarza Kavat's Cat's Eye or Smeeta Kavat's Charm's Critical Chance Bonus: Their power is to respectively boost your crit chance to 60% and set your crit chance to 200%.

Basically, not an hidden mechanic, but mods.
