While not technically black or green, the CZ858, VZ-58, AK-47, AK-74, etc...are generally lumped in with them because they basically share the same general "tactical" niche in terms of range, firepower & intended purpose. They can be equally well discussed under Milsurps. If you want to get really technical, there are aftermarket stock kits for many of these traditionally wood stocked firearms that will make them "black" rifles. Others are being newly manufactured with modern synthetic furniture with/without picatinny rails, etc...i.e., VEPR AK variant, etc...
