I have built several of the stripped FAB10 politically correct lowers. I enjoyed building them and my kids and I like shooting them. They still raise eyebrows when we pull them out at the local range in Agoura Hills. As others have noted, these are "fun" plinker type rifles, and not tatical in any sense. If it ever came to having to reach out and touch someone, then I would more than make do with the M1A and the 1911 style 45.
One other nice thing about the FAB10 is you can build them any way you want. There is no pre or post ban with these. My first one I built up in an A1 style, topped with a mint, in the bag, surplus Colt SP1/M16 upper that I bought via the Equipment Exchange from Georgia Precision. Lightweight and fun to shoot. The second FAB10 was built with a collapsable stock and a flat-top Phantom II carbine upper from Fulton. They were both fun projects, and a nice departure from working on Garands and the M1A.
My local FFL (in Santa Paula) sells the FAB10 if you are interested. Send me an email, and I will give you his name and number.
