+2 Assassin's Crossbow

Like all +2 weapons, the DM adds +2 to the AC hit when using this weapon but the damage bonus has already been factored into the damage wheel.

If a rogue (not bard) scores a critical hit while wielding this weapon, that attack deals triple damage.

Multiplication Note: If the rogue is benefiting from some other effect which causes ranged attacks to deal double-damage, the damage from this weapon gets quadrupled (×4), not sextupled (×6)

Assassin (Sub-Class) Note: +2 Assassin’s Crossbow by itself does not allow the wielder to make a Ranged assassination attempt. For that you’d need a token that specifically allows you to circumvent that rule. (e.g., Lenses of Agility)
