If you want it done absolutely perfectly, then yeah. Get a vice and a torque wrench and a lapping bar and a scope level kit.
Or just do it like 99% of hunters. Use a screwdriver and the universal german torque spec: "guttentite"
If this is a $1500 precision long range rifle, then, by all means, disregard my advice. Otherwise, just watch some youtube videos and set it up yourself. You won't hurt anything by trying and you will learn in the process. Consider getting some blue loctite as insurance on your bases and rings. Best of luck!
