CZ S805

   The new CZ S805 modular assault rifle was revealed in 2009. This weapon was developed in conjunction with the Czech Army and is aimed to replace the ageing vz.58. Currently Czech MoD is planning to obtain several thousands of these new rifles for special forces, reconnaissance battalions, and rapid deployment forces.

   It is a gas operated, selective fire weapon, chambered for the standard NATO 5.56 x 45 mm ammunition. It's design was influenced by the Heckler & Koch G36. Modular design of the S805 enables simple changing of the caliber. This assault rifle can be also converted to 7.62 x 39 mm and 6.8 x 43 mm ammunition. Caliber change is performed by the shooter by simply replacing the barrel, gas-piston unit, breech block and magazine housing. Three barrel lengths are available for each caliber. Consequently this weapon is available in three versions - carbine, standard assault rifle and light machine gun / marksman rifle.

   The S805 has an aluminum receiver. A number of parts are made form polymers.

   An ambidextrous cocking handle can be mounted on either side of the housing. The trigger group is also ambidextrous. It has semi-auto, two round burst, full auto and safe modes. Spent cases are ejected to the right side only, however there is a case deflector, which propels cases from the left-handed shooter.

   The CZ S805 assault rifle is fed from 20-, 30- or 100- round magazines. The 5.56 mm magazines are translucent and allow to determine a number of rounds left. It is worth mentioning that magazine of the CZ S805 is not compatible with other STANAG magazines.

   A polymer shoulder stock folds to the right side. When folded it do not obstructs ejection port. It is adjustable for length. It is worth mentioning that the shoulder stock can be completely removed, without affecting operation of the weapon.

   The CZ S805 assault rifle comes with integral Picatinny-type rail on top of the receiver. It can be fitted with detachable iron sights or a wide array of scopes and night vision sights. This weapon is compatible with a multi-purpose knife-bayonet, 40-mm underbarrel grenade launcher and a number of other accessories. A sound suppressor can also be fitted if required.

   A semi-automatic civilian version is currently under development.
