Cadex Defence is a Canadian firearms manufacturer based in Saint-Jean-sur-Richelieu, Quebec. It produces high-end bolt action rifles, precision sniper rifles, rifle chassis and defence accessories. The company was founded in 1994 as Cadex. Initially it was specialising in helmet and eyewear testing equipment. In 2000, after it secured a number of orders from military units and police departments, it created the defence division. Cadex Defence worked with Remington Arms to create the Remington RACS chassis for the M2010 Enhanced Sniper Rifle, a modern revision of Remington Model 700 rifle. The company offers a similar chassis to Remington RACS under the name Cadex Dual Strike.
