In shooting sports, a shot grouping, or simply group, is the collective pattern of projectile impacts on a target from multiple consecutive shots taken in one shooting session. The tightness of the grouping (the proximity of all the shots to each other) is a measure of the precision of a weapon, and a measure of the shooter's consistency and skill.
The Colt AR-15, a type of semi-automatic rifle. A semi-automatic firearm, also called a self-loading or autoloading firearm (fully automatic and selective fire firearms are also variations on self-loading firearms), is a repeating firearm whose action mechanism automatically loads a following round of cartridge into the chamber and prepares it for subsequent firing, but requires the shooter to ...
The main advantage of semi-automatic rifles is their ability to fire multiple sequential shots quickly, as avoiding manually chambering cartridges helps to maintain the aiming position. Repeatedly engaging single or multiple targets rapidly greatly increases the effectiveness of a firearm in most applications.
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.
Some selective fire weapons utilize burst fire mechanisms to limit the maximum or total number of shots fired automatically in this mode. The most common limits are two or three rounds per pull of the trigger. Selector: The part of a selective fire weapon that allows the user to choose their desired mode of firing.
To qualify as a precision guided firearm, the system must: Be a complete firing system – rifle, ammunition and networked tracking scope; Persistently track the target, automatically compute a multi-variable firing solution, and ensure precise engagement when target and firing solution are optimally aligned
In order to develop a weapon with a more reliable, higher rate of fire, General Electric designers scaled down the rotating-barrel 20 mm M61 Vulcan rotary cannon for the 7.62×51mm NATO ammunition. The resulting weapon, the M134 Minigun, could fire up to 6,000 rounds per minute without overheating. The gun has a selectably variable rate of fire ...
Anti-aircraft machine guns often have extremely high rates of fire to maximize the probability of a hit. In infantry support weapons, these rates of fire are often much lower and in some cases, vary with the design of the particular firearm. The MG 34 is a WWII-era machine gun which falls under the category of a "general purpose machine gun ...
