The C7A1 assault rifle is an improved version of the basic C7 combat rifle, incorporating a low-mounted optical sight. It is a Canadian adaptation of a U.S. firearm known as the M16A1E1. The C7A1 eliminates the carrying handle of the C7 and substitutes an optical sight. The weapon is equipped with a 3.5x optical sight, which is mounted in place of the carrying handle.
C7A1 rounds are 5.56 x 45 NATO standard. The weapon has an effective range of 400 metres and a rate of fire of 700 to 940 rounds per minute. Along with the optical sight, optional attachments include the M203A1 40mm grenade launcher, the AN PAQ 4 Laser pointer and the Image Intensification Night Sight (Kite sight). It has been in service with the Army since 1986.
