##EDIT:
##This guide is outdated, you can find @DemoniteBL’s new guide [here] (Revisited Critical Hit Modifier Guide) for more information.
Disclaimer: There is almost no new info in this thread: most things in here comes from Loot turtle and Sljm’s work on BL2 (which can be found here and here respectively)

This thread is a “port” from a similar work we made for BL2 that lists all critical hit bonus sources in the game, as well as explains the relationship and workings between all of them.
Before we start, a word about the 3 different types of crit modifiers:
Type A is the most common, it’s generally what you get when you have a crit bonus.
Type B or “Jakobs type” only comes from a handful of guns, 95% of them Jakobs. Generally considered more valuable (and is often referred to as a “multiplicative” bonus.)
Type C is not a “bonus” as it’s impact is negative. Assault rifles have it.
the Critical hit equation is as follow:
Crit Damage = Damage * 2 * (1 + .Type A) * (1 + .Type B) / (1 + .Type C)
Guns:
(Note: generally, when a gun has more than one type of bonus, the weapon card will be incorrect.)
Basic guns:
Jakobs snipers: 160%
Other snipers: 100%
Hyperion lasers: 50%
Jakobs Shotguns: 15%
Jakobs pistols: 25%
Jakobs Assault rifles: 15%
Other Assault rifles: 20%
Unique guns:
Fremington’s Edge: 100%, 175% when scoped
Fatale: 75%
Hail: 20% and 200%
Striker: 15% and 50%
Wallop: 15% and 60%
Gwen’s other Head: 37.5%
Gun modifiers:
Snipers critical hit accessory: 20%
Shotguns critical hit accessory: 50%
Pistols with Hyperion Barrel: 7.5%
Hyperion lasers with the Hyperion barrel: 50%

Punishing Luneshine: 10%
Overload (Red) glitch on Snipers and Hyperion Barrel lasers: 50%

A word about Cryo and crits:
The Cryo status effect buffs crit damage (as well as melee and explosive damage). When enemies are frozen, they take an extra 200% bonus damage. In that regard, cryo acts a bit like slag did in BL2 UVHM, but only buffs certain types of damages.
here’s a pretty good video by Poka showcasing this effect:
