I'm a lefty,most stocks can be modified if the action portion of chassis is flat on top, on both sides to clear any bolt stops and port.,some have the material removed in the saftey area for rh or Lh,but no bolt notch.I've made several RH,LH out of wood,plastic and aluminum.I prefer LH bolt,RH eject
Minor machining a Savage RH bolt action into a LH bolt ,RH eject, is not difficult,finding the left hand bolt body can be.
Milling machine is a lefy's No. 1 tool or friend with one.
KRG Bravo,Decent stock for winter time,outer stock is composite,inner is a aluminum.
I just milled a cheap rh TRYBE to lh,made buy MDT to turn a Savage 110 PCS handgun into LHB,RHP rifle.
PDC Customs makes on of the best,he makes LH,he also will make it ambi,he has done several that way for LH CZ457's with extra clearence for RH safety next to bolt stop.
