TAR-21

The TAR-21 is waterproof and lightweight. The weapon has a built in laser and MARS red dot sight, but the TAR-21 can also be mounted with an array of different sights such as a holographic weapon sights, night vision systems and other electronic devices.

The rifle uses a long-stroke piston system to redirect high pressure gases from rounds being fired to eject spent shells and reload new ones.The TAR-21 has ejection ports on both sides of the rifle so it can easily be reconfigured for right or left-handed shooters. However, this process requires partial disassembly, so it cannot be quickly reconfigured while the rifle is in use.The barrel features 6 grooves in a 178 mm (1 in 7 inch) or 32 calibers right hand twist rate. The IDF uses both 55-grain M193 and 62-grain M855 5.56×45mm rounds. M193 rounds will be used by regular infantrymen for better terminal effects at shorter distances, while the heavier M855 will be used by sharpshooters. The barrel has a flash suppressor similar to the one on the M16A2.

The TAR-21 accepts standard STANAG magazines. It can also be mounted with the M203 grenade launcher. Its ambidextrousfire mode selector above the pistol grip has a semi-automatic mode and a fully automatic mod
