Just bought some guns from a friend who'd rather have the cash. One is a Remington Model 700. It has a beautiful walnut Montecarlo stock with cut checkering and scroll work. The stock has black accents. The rifle is blued. The odd part is that it's a 6mm Remington. Never seen one before accept the Varmint Sendero rifle. Looks like the date code is 1972. Any idea what this is? I'd like to sell or trade it for something useful but have no idea what it's worth. No mention of it in the model 700 history.
