SRC AK bodies TM compatible, but their AKS-74U is a VFC clone.
LCT AKs are their own style. Same as Guarder and Inokatsu, all made by LCT back in the day. But they do make TM compatible bodies as well.
ICS are their own thing.
TSD just rebrands, so it depends what the original manufacturer is.
GnG are their own thing (they use 4 screws on the bottom but are not compatible with TM at all), except their newer cheap clear lines that are simply TM clones (not the nicer ones with the full bolt carriers and such).
King arms are TM compatible.
Cyma AK-47 style bodies are TM compatible. Bodies off their sidefolders (AK105/AK74M/AKS74/AKSU) on the older models are close to being compatible with the 4 screws and all. Newer ones are a mix of VFC and LCT style.
JG AK-47 style bodies are TM compatible as well. Their newer AKs (AKSU/AK-74/etc) are VFC clones.
IMO King Arms and SRC make the nicest TM compatible bodies for the price.
