Im trying to replace the handguard, pistol grip, and folding buttstock on a Century VZ2008 Sporter. I know that most people turn their nose up at anything from Century, but my question is are these milspec to the Czech Sa vz. 58?? If I buy a stock system advertised for the 58 will I have any problems mounting it to the century? the stock that came on the rifle looks like its made from recycled grocery bags. I appreciate any help, just dont beat me up too bad for owning the weapon, thank you
