This is a list of United States Army fire control, and sighting material by supply catalog designation, or Standard Nomenclature List (SNL) group "F".The United States Army Ordnance Corps Supply Catalog used an alpha-numeric nomenclature system from about the mid-1920s to about 1958.
The degree of rotation of the compensator determines the range to the target by simple triangulation. [1] Coincidence rangefinders made by Barr and Stroud used two eyepieces, and may be confused with stereoscopic units. The second eyepiece showed the operator a range scale so the user could range and read the range scale simultaneously. [2] [3]
The Barrett Optical Ranging System (BORS) was an integrated ballistics computer manufactured by Barrett Firearms that aids snipers and long-range marksmen in taking precise and accurate shots. The system mounts directly to the riflescope and couples with the elevation knob. With the aid of the BORS, marksmen can rapidly account for temperature ...
The optic has two standard reticles: both are a cross, feature a range finder out to 600 m (656 yd) for 5.56x45 and 800 m (875 yd) for 7.62x51, where they differ is in the bulletdrop design, where the one called CX5395/CX5396 uses circles to denote the range, while the other called CX5455/CX5456 uses lines and also features lines for windage.
The Sight Unit Small Arms, Trilux, or SUSAT, is a 4× telescopic sight, with tritium-powered illumination utilised at dusk or dawn. The full name of the current model is the SUSAT L9A1 . The sight is not designed as a sniper sight, but is rather intended to be mounted on a variety of rifles and to be used by all infantrymen.
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. Assume that a range finder is available that determines that the target is exactly 300 meters distance. 2. Determine the elevation angle of the target.
It can be used standalone on a stock or mounted on the rifle. ... Infantry range finder ... [113] Spotting Scope M/20
A long-range laser rangefinder is capable of measuring distance up to 20 km; mounted on a tripod with an angular mount. The resulting system also provides azimuth and elevation measurements. A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object.
