The Bilge Rat Blunderbuss is a weapon in Sea of Thieves. This Blunderbuss can be purchased from the Weaponsmith's Shop in Outposts. Once purchased, weapons can be accessed and swapped from the Armory located on the player's ship. Ammunition is required to use the Blunderbuss.
Once prone to barrel explosions after overfilling with shot. Should be OK now though.
