Mounting a scope is a basic do-it-yourself project that is easily accomplished. View a couple of videos and dive in. There are countless videos of varying quality available for free on the internet.

I once watched an employee at a gun store mount a scope for a customer so that one of the turrets was on the bottom (that is really wrong). The guys behind the counter at places like BPS may or may not know how to do it properly.

A torque wrench that reads in inch pounds (as opposed to foot pounds) is helpful, but not necessary.
