If you have lots and lots of money you're just dancing on both feet to throw away on lottery tickets, here's your rifle.
The Israelis and the Finns went the other way: they got the solid as a stove bolt/impervious to all debris, dust, rain, rocks AK action and mated it to our 5.56mm NATO. The Israelis even stole the FN CAL folding stock and made the Galil.
Now if only they had figured out a better sighting system and a less amusing/goofy safety, and maybe gravitated towards something in the 6.5mm range,just think how great that would be..
I notice the Israelis are no longer issuing the Galil.
