I recently purchased a set of Uncle Mike's ttuds and swivels for my MK-II LV. The forearm stud is a machine screw, the rear a wood screw. I was told this was the best set up for this gun. In order to install the machine screw I have to take the barrell and action off to countersink a hole for the nut. I have never taken a gun apart before, and was wondering if it is complicated to do. Should I have someone experienced do it for me? Or is it fairly straightforward as to taking apart and assembling the gun?
