How can I upgrade my weapons to level 10?

In multiplayer, I have opened enough crates to get some of my weapons to level 10 (X). But in single player, I can only research upgrades through level 5 (V).

Can you get weapons to level X in singleplayer?

Additionally, is level V the max level for mods?

You can only level up weapons to level X in a New Game+ in single player. V is the max level in your first playthrough.
