I just traded into a Saiga 12 that is not converted. I am looking at converting it. Any advice who had a better parts kit? How long should it take a gunsmith to do the work correctly? Any components better than others? I did go looking at parts kits and there are a lot of options. I am just not up which parts are better quality or not. Appreciate the ideas, opinions and assistance in advance. But please, keep it on topic.
