Aura faint divination; CL 3rd; Weight 1 lb.
This sight can be attached to a single two-handed firearm. When this is done, the sight becomes part of the weapon, but can be removed from that weapon with a full-round action. A firearm wielder can choose to spend a full-round action to make a single shot with a firearm that has this sight. When she does, she can resolve the attack against the touch AC of her target regardless of the range increment.
