Select fire, is the capability of a weapon to be adjusted to fire in semi-automatic, fully automatic, and/or burst mode. [1] The modes are chosen by means of a selector switch, which varies depending on the weapon's design. Some select-fire weapons have burst fire mechanisms to limit the maximum number of shots fired automatically in this mode.
[13] [14] The resulting sound signature is significantly lower than an unsuppressed rifle, and even from a short distance it cannot be recognized as the discharge of a rifle. [15] The VSS Vintorez suppressor and operating systems are exactly the same as the AS Val, but optimised to fire the 9×39mm SP-5 subsonic cartridge with a hardened steel ...
In automatic firearms, burst mode or burst-fire is a firing mode enabling the shooter to fire a predetermined number of rounds, usually two or three rounds on hand held weapons [1] [2] to fifty or more rounds on autocannons, [3] with a single pull of the trigger. This firing mode is commonly used in submachine guns and assault rifles.
The CZ 805 BREN is a gas-operated modular assault rifle designed and manufactured by Česká zbrojovka Uherský Brod. [1] The modular design enables users to change the calibre of the weapon to 5.56×45mm NATO or 7.62×39mm intermediate cartridges by quick change of barrel with gas tubes, breech block, magazine bay and magazine.
The larger diameter, shorter 6 mm cartridge is optimized for these shorter barrel lengths, and would perform less efficiently from rifle-length barrels. The round's muzzle energy is 831 ft⋅lbf (1,127 J) versus 792 ft⋅lbf (1,074 J) for a 5.56 mm bullet, again from the same 10" standard barrel.
The rifle is compatible with Desert Tech caliber conversion kits that allow the rifle to change caliber. [8] [2] This provides a unique feature in which the rifle chassis can accept both intermediate cartridges and full-powered rifle cartridges on the same serial number platform (such as 5.56×45mm NATO and 7.62×51mm NATO magazines).
These early prototypes, initially designated wz. 1981, were modeled on the Soviet 7.62mm AKM assault rifle. [1] As the weapon was intended to be able to launch rifle grenades , a newly designed, multi-functional muzzle device and a sturdier folding shoulder stock were used (the wire stock is a copy of the wire stock used on the East German MPi ...
The felt recoil is therefore eliminated, enhancing accuracy and assisting control during fully automatic fire. The travel distance of the AK-107 reciprocating parts is less than other Kalashnikov designs, so the cyclic rate is higher at 850–900 rounds/min rather than 600 rounds/min on other AK rifles. However, as the felt recoil is virtually ...
