Knight's Armament Company SR-25 semi-automatic sniper rifle
The SR-25 (Stoner Rifle-25) is a semi-automatic special application sniper rifle designed by Eugene Stoner and manufactured by Knight's Armament Company.
The SR-25 uses a rotating bolt and a direct impingement gas system. It is loosely based on Stoner's AR-10, rebuilt in its original 7.62×51mm NATO caliber. Up to 60% of parts of the SR-25 are interchangeable with the AR-15 and M16—everything but the upper and lower receivers, the hammer, the barrel assembly and the bolt carrier group. SR-25 barrels were originally manufactured by Remington Arms with its 5R (5 grooves, right twist) rifling, with twist 1:11.25 (1 complete turn in 11.25 inches or 286 millimetres). The heavy 24 in (610 mm) barrel is free-floating, so handguards are attached to the front of the receiver and do not touch the barrel.
First military purchase was spearheaded by the U.S. Navy in the early 1990s; the first operational deployment and use of the SR-25 sniper rifle was with U.S. Navy SEAL snipers supporting operations in Somalia in 1993.
The Dragunov sniper rifle (formal Russian: Снайперская Винтовка системы Драгунова образца 1963 года Snayperskaya Vintovka sistem'y Dragunova obraz'tsa 1963 goda (SVD-63), officially "Sniper Rifle, System of Dragunov, Model of the Year 1963") is a semi-automatic sniper/designated marksman rifle chambered in 7.62×54mmR and developed in the Soviet Union.
The Dragunov was designed as a squad support weapon since, according to Soviet and Soviet-derived military doctrines, the long-range engagement ability was lost to ordinary troops when submachine guns and assault rifles (which are optimized for close-range and medium-range, rapid-fire combat) were adopted. For that reason, it was originally named Самозарядная Винтовка системы Драгунова образца 1963 года "Self-Loading Rifle, System of Dragunov, Model of the Year 1963."
It was selected as the winner of a contest that included three competing designs: by Sergei Simonov, Aleksandr Konstantinov and Yevgeny Dragunov. Extensive field testing of the rifles conducted in a wide range of environmental conditions resulted in Dragunov’s proposal being accepted into service in 1963. An initial pre-production batch consisting of 200 rifles was assembled for evaluation purposes, and from 1964 serial production was carried out by Izhmash.
Since then, the Dragunov has become the standard squad support weapon of several countries, including those of the former Warsaw Pact. Licensed production of the rifle was established in China (Type 79 and Type 85) and Iran (as a direct copy of the Chinese Type 79).
M14 rifle, officially the United States Rifle, 7.62 mm, M14, is an American selective fire automatic rifle that fires 7.62×51mm NATO (.308 Winchester) ammunition. It gradually replaced the M1 Garand in U.S. Army service by 1961 and in U.S. Marine Corps service by 1965. It was the standard issue infantry rifle for U.S. military personnel in the contiguous United States, Europe, and South Korea from 1959 until it was replaced by the M16 rifle in 1970. The M14 was used for U.S. Army, Coast Guard and Marine Corps basic and advanced individual training (AIT) from the mid-1960s to the early 1970s.
The M14 was the last American "battle rifle" (weapons that fire full-power rifle ammunition, such as the 7.62×51 mm) issued in quantity to U.S. military personnel. The rifle remains in limited service in all branches of the U.S. military as an accurized competition and sniping weapon. It is also used as a ceremonial weapon by honor guards, color guards, drill teams, and ceremonial guards. The M14 serves as the basis for the M21 and M25 sniper rifles.
The M21 Sniper Weapon System (SWS) is the semi-automatic sniper rifle adaptation of the M14 rifle. It is chambered for the 7.62×51mm NATO cartridge.
