A Bolt rack is the form of ammunition used exclusively by Karil's crossbow, Karil's pistol crossbow, and Karil's off-hand pistol crossbow. Bolt racks can be found by opening chests in the Barrows, buying from Ak-Haranu on the Port Phasmatys docks for 420 coins each, or they can be bought from another player. The price of bolt racks is variable on the Grand Exchange so buying them from Ak-Haranu is sometimes cheaper. Used bolt racks cannot be picked up, which makes them a more fiscally consuming bolt type. One bolt rack is used per shot, despite the fact that it is a rack.
