The Windrunner SA99 Takedown is a bolt-action, single-shot rifle chambered for the Browning Machine Gun cartridge (.50 Cal. BMG or 12.7x99mm NATO). This rifle can be differentiated from all others in the fact that it can be taken-down into 5 pieces or assembled, without any tools, in less than 1 minute. The complete take-down overall length is less than 32 inches.

This model shares all the features of the Windrunner Model 98, without the magazine well and the magazine.
