The Grizzco Blaster is a modified type of Blaster Weapons that can only be obtained in Salmon Run. It is a rare Grizzco Industries weapons that can be granted to a player during Wildcard Rotations.

The Grizzco Blaster is an illegally modified version of the Blaster, with the range of a Luna Blaster, but with a very high fire rate that is equivalent to the fire rate of a .96 Gal. It also has the fire power of a "nerfed" Clash Blaster. This weapon is very efficient, capable of firing 32 shots per full ink tank. When used properly, the Grizzco Blaster can do devastating damage to regular Salmonids and take out some Boss Salmonids in seconds, such as the pilot of the Steel Eel or the Scrapper. During Rush waves, it can tear through the berserking Chums quickly, and cause some damage to Goldies before they can slip past to target the player surrounded by Glowflies. This weapon struggles the most with Cohocks because they have 400hp, and this blaster only deals 50 points of damage per direct hit, making it the weakest Grizzco weapon when it comes to the amount of damage dealt per shot. However, it makes up for it by having the fastest fire rate of the Grizzco weapons.
