I have 2 vz58 in 223 love both of them very much plus a conversion to use 10rd lar mags the one upside I see the wk having is from some CGN talk is if you get the 223 wk you could buy a separate upper in 7.62x39 without buying a whole other rifle.
Are you using the plastic mag like the MFT or the steel mag like the CPD ?
