First thing is you have to make sure that the Outback stock was on a gun chambered in one of the WSSM's. If it wasn't it won't work. The WSSM's are not a short-action, they are shorter and a gun that was chambered for a 243, 308, 223, 22-250, etc ,etc their stocks won't work on your WSSM. Second thing you have to consider is the barrel channel. Was the barrel the same diameter as your coyote ? The barrel channel isn't a deal killer if it doesn't match, you can always take a little material from the stocks channel if needed. The most important thing is to make sure that the Outback gun was chambered for a WSSM. Dave
