ohihunter - could you answer a couple of questions? How old is the rifle? How many feet did it drop? What was the air temperature? And, where did the rifle actually hit the ground, under the receiver where it broke or on its side? Did it hit a rock?
I ask as that break almost looks like the receiver was a metal casting for that sharp a break OR it hadn't been properly heat treated. If you know somebody that works with metal that heat treats their work, they may have a "hardness gauge". If you find the metal to be sub-par for a firearm, that might indicate a "manufacturing defect". That's where the age of the gun comes into play as it might still be under warranty. I'm betting it is based on your title. Get the hardness tested, if possible, before contacting CVA as that might make the process easier.
Good luck !
ETA - just saw your post about distance (20') and casting. To have fallen on the scope and not damage it is surprising.
