Antimaterial Rifle

South African DENEL 20X110HS NTW-20 Rifle procured for evaluation in the United States

The antimaterial (antimateriél or equipment) rifle is the successor to the antitank rifle of World War I and early World War II. Essentially a large-caliber, high-velocity rifle firing special armor-piercing ammunition, it is designed to operate against enemy equipment, such as thin-skinned and lightly armored vehicles. The weapon can also be used for long-range sniping. Antimaterial rifles are often favored by special operations military units.

The offensive use of anti-materiel rifles or special application scoped rifles (SASR) is termed hard target interdiction (HTI) by the United States military.

Anti-materiel rifles can also be used in non-offensive roles – for example, for safely destroying unexploded ordnance

The U. S. Army Browning M2 .50-caliber machine gun, which can be fired single shot as a sniper rifle, fits in this category. The Austrian Steyr 25mm antimaterial rifle, with a claimed effective range of 1.2 miles, features both a muzzle brake and a hydropneumatic sleeve to lessen recoil. The weapon has a bipod and can be broken down for ease of transport by its crew. Among other such weapons is the South African Denel NTW-20. This 20mm bolt-action rifle features a 3-round side-mounted box magazine. There is also a 14.5mm model. To reduce recoil, the NTW-20 utilizes a hydraulic double-action damper along with a double baffle muzzle brake.

The British will tell you to beware wily, Dutch-African farmers with rifles.

Among other such weapons are the U. S. Armalite AR50 and Barrett M82A1, both of which fire the 12.7mm NATO (.50-caliber) round; the British Accuracy International AW50F, firing the 12.7mm NATO (.50-caliber) round; the Hungarian Gerpard M1(B) and M2(B) 12.7mm rifles, which with changed barrel can also fire the .50-caliber round; and the Russian KSVK 12.7mm rifle.
