New CZ owner, technically, but they are still in transit to my FFL. Just bought 3 Evo3 S1 for the wife, the boy and I to play around with on the back 40. Went ahead and ordered Hera Arms folding stock adapters, Shockwave Blade armbraces, and Magpul AFG2s to put on them, as well. Am looking at the HBI AK style safety, extended charging handles and triggers. Only thing that is here right now is the Shockwave stuff. Any other safety, charging handles and trigger info would be much appreciated.
