Thats what you should put on your Tshirts right there! How 'bout a green gun with black furniture.

Greetings all! I have perchased my first saiga !!! I had some questions about making some mods. (ie folding stock ect.) I have never bought an import firearm before and with all the rules reguarding U.S. Sec 922R is it legal to add the TG folding stock to my shotgun? (I have NO problem stating that I am green to all the legal stuff.) any advise on a coarse of action/options to leagly build up my sagia 12? The stock it came with is hollow and crapy! Thanks for all your help!
