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.
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. [172] [173] Newer M16s use the newer M855 cartridge increasing their effective range to 600 meters. [128]
Government-specified barrel profile increased to between 0.675 and 0.575 inches; A2: Also referred to as the "government" or "gov't" profile. Barrel profile for which the portion of the barrel in front of handguards is thickened to 0.715 inches; HBAR: A barrel that in some portion is thicker than government-profile, usually underneath the ...
The weapon was essentially a modified M16A1 with a new square handguard to cover the enlarged straight gas tube and almost 1 inch thick heavy barrel to make the barrel less susceptible for overheating and hence increase the sustained or effective rate of fire capability, a carry handle on top of the handguard, with a hydraulic buffer assembly ...
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 ...
The development of the S&T Daewoo K11 dual-barrel air-burst weapon, which uses 5.56×45mm NATO and 20×30mm air-burst grenade, prompted the South Korean military to plan for the replacements of all K2 rifles in service with the K11, making K11 the standard service rifle for the armed forces.

Designated marksman rifles have to be effective, in terms of hit rates and terminal ballistics, at application ranges exceeding those of ordinary assault rifles and battle rifles, but do not require the extended-range performance of a dedicated sniper rifle. For this, depending on the military, sometimes specialized 7.62×51mm NATO ammunition ...
