Has anyone put together an Bulgarian AK74 kit yet? Can anyone explain how to install the firecontrol group for the AK74? Are there any steps and pics available here? I picked up a kit and receiver from ORF awhile back - Bulgarian I think, but I'm left with lots of extra parts and no instructions for this setup. The "AK47" parts differ dramatically from these in that there are more parts included for the "74" and darned if I know whre they are supposed to go. Any help would be greatly appreciated.
