Not very often you find a 222 with a full stock. Uncommon or not, if the bore is pitted or damaged so that the gun is not accurate will put the whole package on a gunsmith's bench for a few hours turning a new barrel to the correct contour for the stock and refitting the sights. If the bore was good, I wouldn't balk at paying $450... the light cosmetic damage is not difficult to repair... it's just paint gone off the aluminum and some blue rubbed off the steel floorplate with some pitting. Looks like some of the chrome plating has chipped off the bolt knob... light wood scratches are normal on guns that are used. I like how that rifle looks and that someone bothered to make such a gun in 222... most full stocks are big game calibers.
That scope (don't even recognize what it is) is ghastly on that particular rifle but that's also easy to change. (It needs something like a Leupold VX2 ~ 2-8x(less than 40mm ) in gloss finish and mounted in lower rings)
