You are not limited to the stripper clip top-loader as was the previous plan. According to DSA, you can order any rifle from their inventory and they will ship it to your dealer minus the pistol grip with a 10-round magazine, which they already produce. I don't remember if I read it here or at FAL Files, but someone mentioned seeing some guys at the range with the pistol grip duct taped to their hand. They would slide the grip on the pistol grip stud (you don't need the nut), fire their mag, and slide it off. This is certainly not the ideal solution, but they got away with it and didn't have to drive to Nevada to break-in and sight-in their rifle. I don't know if it's legal or not.
If you live in the Bay Area and don't have an FFL who will handle the transfer, I would suggest you call M&N Armory in Fremont as he is already a stocking Entreprise dealer and seems like the kind of guy who would do the transfer.
Anyway, the goal is to acquire SA rifles in CA. Maybe the FAL is not your first choice, but compared to having nothing it's a no brainer. :)
