Rate of fire may also be affected by ergonomic factors. For rifles, ease-of-use features such as the design of the bolt or magazine release can affect the rate of fire. For artillery pieces, a gun on a towed mount can usually achieve a higher rate of fire than the same weapon mounted within the cramped confines of a tank or self-propelled gun ...
The modifications to the basic MG 42 design include an extra heavy bolt (950 g (33.51 oz) vs. the 675 g (23.81 oz) MG 3 bolt) which reduces the cyclic rate of fire to around 850 rounds per minute. The rate of fire can be varied up to cyclic rate of fire of around 1,150 rounds per minute, if necessary, by changing the bolt and return spring.
The 30 mm 2A42 autocannon was developed as a replacement for 2A28 Grom and has a dual feed. One is for HE-T and the other for AP-T rounds. The gunner can select one of two rates of full automatic fire, low at 200 to 300 rds/min and high at 550 to 800 rds/min. [4] According to the manufacturer, effective range when engaging ground targets such as light armoured vehicles is 1,500 m (4,900 ft ...
The standard Uzi has a 10-inch (250 mm) barrel. It has a rate of automatic fire of 600 rounds per minute (rpm) when chambered in 9mm Parabellum; the .45 ACP model's rate of fire is slower at 500 rpm. [21] A Mini Uzi. The Mini Uzi is a smaller version of the regular Uzi, first introduced in 1980. The Mini Uzi is 600 mm (24 in) long or 360 mm (14 ...
The M249 SAW combines the rate of fire of a machine gun with the accuracy and portability of an assault rifle. The M249 SAW is gas operated and air-cooled. It features a quick-change barrel (enabling the operator to rapidly replace an overheated or obstructed barrel) and a folding bipod attached to the front of the weapon (an M192 LGM tripod is ...
The M2 has varying cyclic rates of fire, depending on the model. The M2HB air-cooled ground gun has a cyclical rate of 450–575 rounds per minute. [29] The early M2 water-cooled AA guns had a cyclical rate of around 450–600 rpm. [30] The AN/M2 aircraft gun has a cyclic rate of 750–850 rpm; this increases to 1,200 rpm for AN/M3 aircraft guns.
United States naval gun terminology indicates the gun fires a projectile 5 inches (127.0 mm) in diameter, and the barrel is 54 calibers long (barrel length is 5" × 54 = 270" or 6.9 meters.) [1] In the 1950s, a gun with more range and a faster rate of fire than the 5"/38 caliber gun used in World War II was needed; therefore, the gun was ...
Weighing approximately 12 pounds (5.45 kg) with a loaded 71-round drum and 9.5 pounds (4.32 kg) with a loaded 35-round box magazine. The PPSh is capable of a rate of about 1250 rounds per minute, [28] a very high rate of fire in comparison to most other military submachine guns of World War II. It is a durable, low-maintenance weapon made of ...
