I think this rifle either sold a couple years ago and is back on the market, or they may just be leaving it on the site for interest.
All in all, a well executed rifle other than the choice of wood and the front sight doesn't look to be particularly well fit.
Regarding the wood, is maple inherently more brittle than walnut?
Seems like there would be all sorts of opportunity for a birdseye maple stock to form cracks, especially in a .458 Lott.
