If it's not blemished I would think you could get 350 (give or take) for it?, especially from someone that is more of a fan of the sitka pattenr than I. The problme with those, the ascents and adirondacks is that finish is boarder line garbage and doesn't withstand near the abuse the solid color montana or ascent stocks do. The camo wouldn't be a price raiser in my eyes (if anything the opposite) but may to others.
I was quoted a similar price from kimber for a replacement montana stock. Trying to think about it from my own standpoint if someone had a perfect, never shot montana 8400wsm stock for $350 I'd consider it, I'd be all over it for $300. If you start asking close to the full price I'd personally start looking at other, after market options for not much more.
