EGWs are nice for looks, but as na1lb0hm suggests, aren't really necessary. I've built-up a 93 with a Boyd's stock and the necessary metal from Savage. (mag plate, trigger guard, fasteners) and I think it was about $175+ when the dust settled. I recently bought a Savage FV-SR (.22lr) that has a factory EGW base, if you want to know what they look like on a Savage 93-type action. I knew going in I didn't want to blow a hole in a $200 bill

so I ordered a black rubber, "monte carlo" screw-on riser from "Accu-Riser" in the states. Makes these Savage stocks perfectly acceptable, even pleasant to use. I'm very pleased, and feel NO temptation to go the Boyd's route. As nice as they are. In fact, it's re-ignited my interest in getting another 93FV one day..
I've posted this photo a couple of times recently, but this is my daughter putting the FV-SR to good use on some shotgun hulls @ 50 yards.
