The C7 is a variation of the M16 rifle that is manufactured by Diemaco and used by the Canadian Armed Forces as its main infantry weapon. Following trials, it also the weapon of choice of the British SAS.

It is a variant of the M16A1E1; like earlier M16s, it can be fired in either single shot or automatic mode. Many of the modifications made for the C7 were sold back to the US and incorporated in the M-16A2.

The C7A1 replaces the iron sight/carrying handle used on the C7 and M16 with variable Picatinny rail mount. The mount can use traditional iron sights or the C7/9 3.4x power optical sight, both of which can be adjusted for individual eye relief. The optical sight was designed for the C9 light machine gun and includes horizontal and vertical mil-bars used for range determination and deflection, and a tritium glow-in-the-dark aiming parapet rather than the tradition crosshairs. The 3.4x is powerful enough to properly see targets at the maximum accurate range of 300m while in no way interfering with target speed acquisition or close quarters combat as most optical sights would.

The C8 carbine is the Canadian variant of the XM177 Colt Commando. Unlike the Commando, the C8 has a barrel longer than that of the M4 Carbine but shorter than the M16. This design combines the accuracy of a full-length rifle (such as the M16) with the weight and rapid target acquisition of a compact carbine (such as the M4).

The C8 is usually fielded to the Canadian Special Forces.
