A C79 Optical Sight. The C79 optical sight (SpecterOS3.4x) is a telescopic sight manufactured by Elcan. A variant, the M145 Machine Gun Optic is in use by the US military. It is 3.4×28, meaning 3.4x magnification, and a 28mm diameter objective lens. A tritium illuminated reticle provides for normal and low-light conditions sighting. [1]
Assume a rifle is being fired that shoots with the bullet drop table given in Table 1. This means that the rifle sight setting for any range from 0 to 500 meters is available. The sight adjustment procedure can be followed step-by-step. 1. Determine the slant range to the target.

The iterative procedure involves firing a group of shots from a cool gun barrel, then determining the geometric center of the shot pattern, adjusting the sights to move the point of aim to that group center, and repeating the process until further groups consistently center on the point of aim.
Denmark: Hæren adopted three custom versions developed jointly between DALO and Elcan in 2020. The models picked where the Specter DR 1–4× for 5.56, Specter DR 1–4× for 7.62 and the Specter DR 1.5–6× for 12.7 as all with a unique reticle and was adopted as a replacement for the ageing C79. [15]

The diopter sight is easy to use and usually allows for very accurate aiming, because a relative long sighting line can be used. A long sighting line helps to reduce eventual angle errors and will, in case the sight has an incremental adjustment mechanism, adjust in smaller increments when compared to a further identical shorter sighting line.
The FN FAL from which the L1A1 Self-Loading Rifle was derived was not designed for mounting optical sights like the SUIT. To mount the SUIT, a new top cover was designed. This had a rail welded to the top to accept the sight mount, and two tabs at the rear of the pressed sheet steel cover which butted against the back of the upper receiver, preventing the cover from sliding on its rails and ...
