In 2002, Colt Defense was split off from Colt's Manufacturing Company. Colt's Manufacturing Company served the civilian market, while Colt Defense served the law enforcement, military, and private security markets worldwide. The two companies remained in the same West Hartford, Connecticut location cross-licensing certain merchandise before reuniting in 2013. Following the loss of its M4 contract in 2013, the reunited Colt was briefly in Chapter 11 bankruptcy, starting in 2015 and emerging in January 2016. The company was bought by Česká zbrojovka Group in 2021.
