version of the US Colt Model 723 (M4)
carbine. Technical data package was provided by Colt to the
Canadian Government. However Canadian Diemaco reviewed the design
and made numerous changes to this weapon, before it entered
production. These changes include materials and manufacturing
processes. Improvements are similar to those of the
C7 assault rifle.

that do not need a full-size assault rifle, such as vehicle drivers, artillery crews, airborne
troops and special operation units. The C8 carbine was adopted in 1994. Currently it is used
by the Canadian armed forces. Also this weapon has been exported to

police. In 2005 Diemaco was acquired by Colt Defense and became
known as Colt Canada Corporation.
