A sniper rifle is a precision-rifle used to ensure more accurate placement of bullets at longer ranges than other small arms. A typical sniper rifle is built for optimal levels of accuracy, fitted with a telescopic sight and chambered for a highly accurate military cartridge. Sniper rifles manufactured for military service are often designed for very high durability, range, reliability, sturdiness, serviceability and repairability under adverse environmental and combat conditions, at the sacrifice of a small degree of accuracy. Military snipers and sharpshooters may also be required to carry their rifles and other equipment for long distances, making it important to minimize weight.
Modern sniper rifles are also anti-materiel rifles (AM or AMR). An AMR is a rifle that is designed for use against military equipment (materiel), rather than against other combatants (“anti-personnel”). The AMR started life during World War II as anti-tank rifles. While modern tanks and most other armored vehicles are too well protected to be affected by anti-materiel rifles, the guns are still effective for attacking unarmored or lightly armored vehicles. They can also be used against stationed enemy aircraft, missile launchers, radar equipment, small watercraft, communications equipment, crew served weapons and similar targets. Their value is in being able to precisely target and disable enemy assets from long range for a relatively low cost.
