Brass Eagle Tigersharks. These are bore drop Nelson-based pumps, however, all of the parts are proprietary and not compatible with any other nelson clone. The introduction of the Tigershark in the early 90's marked a new direction for Brass Eagle, as the company began focusing on very basic, low cost entry-level guns. The purchase of Brass Eagle by Daisy lead to a wider distribution network, and the Tigershark was one of the first paintball guns to be sold in national chain department stores.
