any MIL-STD-1913 Picatinny rail or receiver. Zero is retained despite repeated removal and re-attachment to the weapon. The M145 is extremely resistant to shock and water immersion and has an anti-reflection device and rubber lens caps. The M145 also uses a unique reticle system designed for machineguns wherein there is no single particular crosshair zeroed at a certain distance but instead the sight uses several smaller crosshairs that are marked with specific distances. The machinegun's projectile ballistics are zeroed to match these specific distances so that users can quickly engage targets at extended ranges without having to adjust the sight.

At close ranges, when rapid aiming is required, the emergency battle sights on top of the sight can be used, although they are very crude and only intended for use inside of 75 m.

The reticle is illuminated by a battery-powered LED with varying intensity settings. The mount fits directly to

The reticle of the C79 sight was designed to serve on the C9 Light
Machine Gun, thus an appropriate pattern was chosen to aid the gunner in judging distance. The reticle consists of a single vertical post with a sharp tip in the center. The tip is flanked by horizontal Mil-bars on either side. Under

The C79 sight is attached to a mounting rail on the receiver of the weapon. On
Canadian Forces weapons, this is in the form of a modified Weaver rail, also known as a "Diemaco rail". Two adjustment knobs are used to secure the base to the receiver. A bore-sighting device is usually used to roughly

Canadian service, all C7A1 and C7A2 rifles come equipped with a C79 sight as standard. The C7A1 uses a C79 sight, which is easily distinguished by its matte black rubber overcoating. After reviewing feedback from the soldiers who used the sight, Elcan produced the
