Our Assessment: The Canadian Diemaco C7 Light Support Weapon (LSW) is a variant of the M16 rifle, designed for sustained fire roles in infantry squads. Diemaco, now part of Colt Canada, developed the C7 series as a modified version of the M16A2, tailoring it to meet the requirements of the Canadian Armed Forces. The C7 LSW is intended to serve as a squad automatic weapon (SAW), providing a higher rate of fire and greater firepower than the standard C7 rifles. The C7 LSW retains the core design of the M16 platform, including the 5.56x45mm NATO chambering, but incorporates several changes to enhance its role as a support weapon. One of the key modifications is its heavier, longer barrel, which improves heat dissipation and allows for more sustained fire without overheating. This feature gives the C7 LSW an advantage in prolonged engagements, where automatic fire is required to suppress enemy forces. This C7 LSW also features a bipod, providing the stability needed for accurate automatic or rapid semi-automatic fire. The bipod allows the shooter to support the weapon during long bursts, maintaining better control and accuracy than shooting from the shoulder or unsupported prone positions. This rifle in particular has a properly marked Diemaco upper & barrel with a proper bipod and forend. The lower is a non-color matched Colt AR-15A4 with A2 furniture.
Overall, the Canadian Diemaco C7 LSW serves as a critical component of the Canadian Armed Forces’ small-unit tactics, offering a balance between the mobility of a rifle and the sustained fire capability of a light machine gun. Its robust design, high-capacity magazines, and integration of M16-based components make it a versatile and effective support weapon in a variety of combat scenarios. This rifle would make a fantastic piece for collectors or anyone that wants to get their hands on real Canadian C7 parts. -R.E.
