Spent the afternoon converting my Saiga 12 today. It took a few hours- I spent a lot of time following Youtube vids to make sure I didn't screw anything up.
I went with the CSS trigger guard and trigger group, MFT Engage pistol grip, Tapco standard AK buttstock and metal barrel thread ptotector. It went pretty smoothly, except for that pain in the ass BHO spring. One thing I have to pass on is that Dupli-color part # DE1634 Low Gloss Black engine paint is a PERFECT match to the original Saiga paint.. I didn't have to do any masking at all- Just hit it with wax & grease remove and spray
