The standard saiga triggers for the 7.62, 5.45, and 5.56 models are decent enough. The trigger for the .308 is terrible. I replaced the fcg (counts as 3 parts) and stock (1 part) on my 7.62 to achieve the correct number of US compliance parts...You need to replace at least 4 foreign parts with US parts if you modify a stock saiga and make it truer to original form.
A buddy took in a fal at his shop a few months ago when this subject came up. One dumba** regulation.
