I would talk to one of the heat treating outfits,before parting it out.It's a positive sign that not all the springs were ruined, and that the front scope mount didn't come unsoldered.If the barrel is still bright, you might still have a chance.Thin parts, like small springs, might get to the critical temp.,and the heavier parts not.Spalling on the steel parts isn't a good sign,though.
