The AO-63 assault rifle was used by the Spetsnaz during the Abakan trials in May/June 1986, in search of a more accurate alternative to replace the standard issue AK-74.It was described in the official report as being highly accurate as well as simple and reliable; despite its accuracy and performance, it was later dropped out of the competition for unknown reasons, with the AN-94 emerging ...
This proven system was combined with a purpose-made mounting, capable of fast elevation and traverse speeds, to track incoming targets. An entirely self-contained unit, the mounting houses the gun, an automated fire-control system and all other major components, enabling it to automatically search for, detect, track, engage, and confirm kills ...
Typical cyclic rates of fire are 600–1100 rpm for assault rifles, 400–1400 rpm for submachine guns and machine pistols, and 600–1,500 rpm for machine guns. M134 Miniguns mounted on attack helicopters and other combat vehicles can achieve rates of fire of over 100 rounds per second (6,000 rpm).
Firearm muzzle velocities range from approximately 120 m/s (390 ft/s) to 370 m/s (1,200 ft/s) in black powder muskets, [3] to more than 1,200 m/s (3,900 ft/s) [4] in modern rifles with high-velocity cartridges such as the .220 Swift and .204 Ruger, all the way to 1,700 m/s (5,600 ft/s) [5] for tank guns firing kinetic energy penetrator ammunition.
The Fast Forty is an improved version of the Compact mounting with a higher fire rate of 900 round/min (450 round/min × 2), dual magazine and dual feed mechanism to allow switching from High Explosive (HE) rounds to Armour-Piercing Fin-Stabilized Discarding Sabot (APFSDS) rounds when a target gets within 1,000 meters from the vessel.
It is currently the fastest production .22 caliber round in the world with muzzle velocities as high as 4,600 feet per second (1,402 meters per second). However, the .220 Swift still holds the record as the fastest .22 caliber centerfire cartridge with a published velocity of 4,665 ft/s (1,422 m/s) using a 29-grain (1.9 g) projectile and 42 ...

In the spring of 2007, TDI announced their development of a new submachine gun. It was an experimental weapon under advanced stages of development at that time. The name Kriss comes from a Southeast Asian dagger with a flame-shaped blade. [6] [7] The second generation prototype of the Vector, called the K10, was announced at 2011 SHOT Show. It ...
