It’s not a Winchester model 70 Extreme Weather SS but I occasionally see Montana Rifle Company Xtreme X3 in .308 Winchester for sale as new old stock. I believe the idea behind the MRC Xtreme X3 was to make an upgraded Model 70 Extreme Weather SS. I see a few now NOS on Gunbroker chambered in 6.5 CM and an X2 in .308 Win.
