I'm thinking about taking advantage of the sale & upgrade both the Revolver & Marksmen Sniper. But I have a couple of questions:
1) Can a MkII Revolver with FMJ rounds kill a Kuruma occupant(s) with a single shot?
2) I only used the Marksman Sniper once (when Heists came out), is it worth it?
Can't answer your first question as I've only used incindeary and hollow point rounds for it. As for the marksman Rifle mk2, you gain the ability to use it without the scope but the auto aim distance isn't really that far in comparison to weapons like combat MG mk2, plus the ROF is low so it's only OP in realitively close quarters. IMO, there are better weapons for these situations like the bullpup Rifle mk2 or shotgun so I would save your money.
