From what I can make out, it appears that the Czech Army may be planning to replace their well known Vz. 58 assault rifles.

Vz. 58 rifle

All the articles I have read were very badly written and incredibly confusing. The Czech news website Ceskenoviny.cz , for example, seems to be confused by the different between a pistol and a rifle.

The new arms will replace machine guns 58 based on the Soviet-made Kalashnikovs AK 47, Pravo writes.

…

“It was originally said that only special units will get offensive handguns. The whole military could be rearmed for two billion crowns,” Seda told Pravo.

It writes that the military also plans to spend 3.49 billion crowns on the purchase of light armoured vehicles. Next year 418 million crowns are to be spent on the purchase and a greater part in 2013 and 2014.

Earlier this year I covered the launch of the CZ S805 rifle, which was developed in conjunction with the Czech Army. I guess that this will be the replacement.
