  2. M16 rifle - Wikipedia

    en.wikipedia.org/wiki/M16_rifle

    This concurs with the pre-M16A2 maximum effective range of 460 m (503 yd). [112] The Colt 3×20 telescopic sight was factory adjusted to be parallax-free at 200 yd (183 m). [ 113 ] [ 114 ] In Delft, the Netherlands Artillerie-Inrichtingen produced a roughly similar 3×25 telescopic sight for the carrying handle mounting interfaces.

  3. Point-blank range - Wikipedia

    en.wikipedia.org/wiki/Point-blank_range

    [1] [2] For targets beyond-blank range, the shooter will have to point the barrel of their firearm at a position above the target, and firearms that are designed for long range firefights usually have adjustable sights to help the shooter hit targets beyond point-blank range. The maximum point-blank range of a firearm will depend on a variety ...

    en.wikipedia.org/.../Comparison_of_the_AK-47_and_M16

    Note ****: The maximum range of a small-arms projectile is attained at about 30° elevation. This maximum range is only of safety interest, not for combat firing. [14] The M16 rifle is "accurate beyond description". [171] Its light recoil, high velocity, and flat trajectory allow shooters to take headshots out to 300 meters.

  5. Effective range - Wikipedia

    en.wikipedia.org/wiki/Effective_range

    With the addition of clinometers fixed machine gun squads could set long ranges and deliver plunging fire or indirect fire at more than 2,500 m (2,730 yd). This indirect firing method exploits the maximal practical range, that is defined by the maximum range of a small-arms projectile while still maintaining the minimum kinetic energy required to put unprotected personnel out of action, which ...

  6. Range of a projectile - Wikipedia

    en.wikipedia.org/wiki/Range_of_a_projectile

    g is the gravitational acceleration—usually taken to be 9.81 m/s 2 (32 f/s 2) near the Earth's surface; θ is the angle at which the projectile is launched; y 0 is the initial height of the projectile; If y 0 is taken to be zero, meaning that the object is being launched on flat ground, the range of the projectile will simplify to:

  7. 5.56×45mm NATO - Wikipedia

    en.wikipedia.org/wiki/5.56×45mm_NATO

    The maximum effective point target range of an M4 carbine with M855 rounds is 500 m (547 yd), with a maximum effective area target range of 600 m (656 yd). These mark the greatest distances the rounds can be expected to accurately hit the target, not the ranges that they have terminal effectiveness against them.

  8. 125 mm smoothbore ammunition - Wikipedia

    en.wikipedia.org/wiki/125_mm_smoothbore_ammunition

    It has an effective range of 75 m to 5000 m, and takes 17.6 seconds to reach maximum range. Refleks can penetrate about 900 millimetres (35 in) of steel armour and can engage low-flying air targets such as helicopters. [14] Country of origin: Soviet Union; Projectile weight: 16.5 kg; Warhead weight: 4.5 kg; Guidance system: Laser beam riding

    Figure 1: Rangekeeper Coordinate System. The coordinate system has the target as its origin. The y axis value range to the target. US Navy rangekeepers during World War II used a moving coordinate system based on the line of sight (LOS) between the ship firing its gun (known as the "own ship") and the target (known as the "target").
