The rifle itself is offered in two variants: the S-5.56 A1 with a 19.9-inch barrel and 1:12 pitch rifling (1 turn in 305 mm), optimized for the use of the M193 Ball cartridge; and the S-5.56 A3 with a 20-inch barrel and a 1:7 pitch rifling (1 turn in 177, 8 mm), optimized for the use of the SS109 cartridge.

The maximum effective range is approximately 150 meters. [211] This cup-type launcher can also be used to launch tear-gas grenades. All current M16 type rifles can mount under-barrel grenade-launchers such as the M203 and M320: All current AK-47 type rifles can mount under-barrel grenade-launchers such as the GP-25 series
"At ranges over 500 m (550 yd), a battlefield target is hard for the average rifleman to hit. Therefore, 500 m (550 yd) is considered the maximum effective range, even though the rifle is accurate at much greater ranges". [8] Simultaneously, armies of both sides had put submachine guns to extensive use.
However, high cost and skepticism over the effective firepower of the 20mm grenade led to the decision to provide 2 K11s to each squad, keeping 2 grenadiers as well. Consequently, the standard 9-person infantry squad of the Republic of Korea Armed Forces is currently equipped with 2 K2 rifles, 2 K2 rifles with K201 grenade launcher, 2 K11 DAWs ...
The Close Quarter Battle Receiver (CQBR) [5] is a replacement upper receiver for the M4A1 carbine developed by the US Navy.. The CQBR features a 10.3 in (262 mm) length barrel (similar to the Colt Commando short-barreled M16 variants of the past) which makes the weapon significantly more compact, thus making it easier to use in, and around, vehicles and in tight, confined spaces.
The barrel was changed to a DPMS Ultra Match barrel with a 1 in 8" RH twist, and the M16A1 stock and pistol grip were replaced with A2 versions. The third generation rifle, introduced in 2004, retained the second generation features but replaced the Tasco scope with a Bushnell variable 3-9 x 40mm scope with a Mil-dot reticle, mounted with three ...
To increase the range of the Minimi, the round was created to penetrate 3.5 mm of steel at 600 meters. The SS109 had a steel tip and lead rear and was not required to penetrate body armor. Barrels required at least a 1:9 in rifle twist, but needed a 1:7 in rifle twist to fire tracer ammunition.
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 ...
