Test drill from top and bottom to locate the aluminum bedding block. Look for aluminum shavings to determine depth. Mill on the side that gives you room for half inch aluminum square stock and still be able to fill and sand to the original contour ....if possible. mill milling a half inch spot/key 1/8th inch the bedding block. Drill 4 screws holes on each end/corner of the square bushing to match tapped holes.

Mount and fill. Epoxy mount in the bushing. this will make your project bullet proof and could be done on any mill with some good cribbing and a good vice.
i think i follow what you are saying.
That said, i know where the aluminum is at this point as the swivel stud holes are drilled all the way thru to the barrel channel and the aluminum is the only part threaded for the screws. So pushing the screw in from the barrel channel and from under the stock confirms its about dead center. Only about 1/8th inch closer to the barrel channel, not leaving enough room to go above, or below the aluminum reinforcement. It will have to be embedded into the aluminum as well. That is why im thinking mill the channel (from the barrel channel side) instead of drilling/boring. This way i can leave about 1/8" of aluminum untouched to jb weld the spigot to. then drill and tap the spigot to accept the very same swivel studs. Fill in the channel and finish the stock cosmedicaly. Then the two swivel studs screw into the spigot bar, sandwiching at least some of the original aluminum support between the stock and spigot. So kinda double duty. I know a mill can accomplish this task in just a few minutes. the rest i can do at home. Currently this is my plan. Unless my machinist friend has a better idea

going to be a lot of work just for a bipod lol. But when you want something that does not exist.......
