Premade table for range estimation showing target sizes, distances and corresponding angular measurements. Angular sizes are given in milliradians, ranges in meters, and target sizes are shown in both in centimeters, millimeters and inches. Many telescopic sights used on rifles have reticles that are marked in mrad. This can either be ...
The Low Level Bombsight, Mark III, sometimes known as the Angular Velocity Sight, was a Royal Air Force (RAF) bombsight designed for attacks by aircraft flying below 1,000 feet (300 m) altitude. It combined components of the Mark XIV bomb sight with a new mechanical computer .
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]
Reflector sights were invented as an improved gun-sight and since their invention they have been adapted to many types of weapons. When used with different types of guns, reflector sights are considered an improvement over simple iron sights (sights composed of two spaced metal aiming points that have to be aligned). [16]
Norden proposed removing the electrical switches used to move the pointer and using the entire bombsight itself as the indicator. In place of the thin metal wires that formed the sights on the Mark III, a small low-power telescope would be used in its place. The bombardier would rotate the telescope left or right to follow the target.
In 1926, the British Army changed its nomenclature; the SMLE became known as the Rifle No. 1 Mk III or III*, with the original MLE and LEC becoming obsolete along with the earlier SMLE models. [37] Many Mk III and III* rifles were converted to .22 rimfire calibre training rifles, and designated Rifle No. 2, of varying marks.

Originally (from 1889) Martini–Henry conversions used Metford rifled barrels (and were known as Martini–Metford rifles), which were more than suitable for the first .303 cartridges, which used black powder as a propellant but wore out very quickly when fired with cordite/nitrocellulose cartridges (introduced in 1895). In 1895, the Enfield ...
