Depends on the aftermarket stock you choose. I assume you are going to need to pillar and glass/epoxy bed any of the wood/laminated aftermarket stocks to get the most accuracy potential. The Accustock recoil lug should work fine until you need to replace the factory barrel with a custom match barrel for F-Class. At that time, I would replace the factory recoil lug with an aftermarket precession ground recoil lug.
