The EDM Arms Windrunner is a bolt-action, magazine-fed, takedown sniper rifle created by American firearms designer Bill Ritchie. Several models are available: the M96 (chambered in .50 BMG or .510 DTC EUROP), the M98 (chambered in .338 Lapua Magnum), the XM (chambered in .408 Chey Tac) and the M12 (chambered in 7.62x51mm NATO and .223 Remington). All models have no forearms, though several manufacturers, including Cheyenne Tactical and RND Manufacturing, produces forearms which can be fitted onto a Windrunner.  The biggest seller is the M96 in .50 BMG.
A modified version of the Windrunner is manufactured by Cheyenne Tactical as the CheyTac M200 Intervention. The smaller reciever version of the Windrunner, previously manufactured by EDM Arms as the Mini-Windrunner, is currently manufactured by Nemesis Arms as the Vanquish.
