I've got a McMillan with the integral cheek piece. Is it possible to upgrade now to the thumb wheel cheek piece? Is that the $45 dollar one listed under GAP's services page?
That price is to order a new stock with the thumb wheel upgrade in addtion to the the adj cheek piece. If you already have a MM stock with the standard two screw adj piece I do not belive it can be changed out now.
I have done a number of them. You need the stock cut and, what I use, is the Mcgee adjustable cheek hardware. I think the hardware alone runs almost $100 and the labor involved is around that also.
