The Vz.58 Czechs out

Some interesting things have been posted over at The Firearm Blog – which I’m only just now catching up on…

First up is the news that the Czech Army appear to have decided – at last – to ditch their ancient Vz.58 rifles for a modern, 5.56x45mm NATO chambered weapon.  However, true to their traditions they have developed its successor themselves.

The new rifle, designated CZ S805A (in its standard infantry configuration), is a home-grown “3rd generation” design that was first publically revealed at the IDET military expo in Brno back in May.

The standard assault rifle / carbine is chambered for 5.56x45mm NATO ammunition.  However, the rifle can also be modified to fire 7.62x39mm M43 or 6.8x43mm Remington SPC ammunition by swapping out the barrel, bolt head, magazine well and magazine.  

An Automatic Rifle and a Designated Marksman Rifle version are also available.  All versions feature a trigger group with semi-auto, 2-round burst and full-auto settings.

The rifles feature an aluminium upper receiver and a polymer lower receiver, mag well, pistol grip and side-folding / adjustable-length stock.  the rifle also features a full-length built-in Picatinny Rail on the upper receiver and 3 shorter rails attached to the sides and bottom of the forward receiver.

The standard 5.56x45mm NATO magazine is made from semi-transparent polymer – but appears to be a unique design which is not interchangeable with any other 5.56x45mm NATO magazines.

A modular underslung grenade launcher system has also been designed to accompany the new rifle.
