What's it's worthLooks like a Mark V stainless that someone put in a Bell & Carlson stock.
Nothing wrong with it, as we have some in the same configuration.
I'd bed the action and tune the trigger, and it probably will shoot very well.
Theses are all I got
My serial was SS006214I had one just like that it that I sent to scorehi in New Mexico that added the BC exact stock, tapped the scope mounts to the larger M700 screws , it shoots amazing! I was offered a good price for a friend that wanted it so he has it now and it's still shooting 215hybrids into 1/2 groups. He is an outfitter and the rifle gets used my different clients that come with rifles that can't shoot long distance confidently.
