Firefright and Whitout Remorse RED BORDER!

[shell badger]

is there any good way to farm the red borders for these two weapons ?
i want specially the Whitout Remorse for my builds whit knife because its hard to get a good shotgun from random drops

[sullen crag]

nah no good way, just spamming containment and the story mission when you get the special drop is the only way afaik

you could buy them and should buy the red border every week, but i would not recommend buying more since the rates for buying proceeding red-borders from RNG is very bad
