I bought a r700 5r I want a new stock, and I want a SS 5-20 scope and they are on sale ( thanks facebook). I have to choose one. they are pretty much the same price, I am torn between a whiskey 3 stock and a manners with an adjustable cheek. can you guys help me a little. I have a nikkon prostaff 3-9x40 on it already. and I think the stock would help with the accuracy. The range I am joining is out to 600 yards.
