C7 Rifle with M203 grenade launcher

The Colt Canada C7 is the Canadian military’s adoption of Colt’s Armalite AR-15 platform, manufactured by Colt Canada (formerly Diemaco), having similar design and function to the M16A3.

The C7 and its variants have been adopted as the standard-issue rifle by the militaries of Canada,

The Colt Canada C7 is a highly reliable and accurate service rifle issued to the Canadian Armed Forces since 1977. It is a licensed version of the M16 assault rifle and boasts a design similar to the Colt M16A2. The C7 has been specially crafted to suit Canada’s cold weather conditions. The gun features a longer barrel than its American equivalent, enhancing its accuracy at longer distances.

The Colt Canada C7 is specifically a Colt Model 715 AR-15 rifle, while the M16 designation has been used for the Colt Model 604, 613K, 613P, and 614 AR-15 rifles. The Colt Canada C7 assault rifle was developed in parallel with the M16A2 by Colt. Colt provided the Canadian government with a technical data package, but the Canadian company Diemaco made over 150 modifications to the design before it went into production. These changes included changes to materials and manufacturing processes. The C7 was adopted as the standard infantry rifle by the Canadian military in 1984

he M203 is a single-shot, pump action,40 mm under-barrel grenade launcher designed to attach to a rifle. It uses the same rounds as the older stand-alone M79 break-action grenade launcher, which utilizes the high-low propulsion system to keep recoil forces low. While compatible with many weapons, the M203  launcher can also be mounted onto a C7, a Canadian version of the M16 rifle; this requires the prior removal of the bottom handguard.
