I am trying to decied between these two stocks, I am planning on buying a 700 Police this weekend and would like to upgrade the stock to either the aics or the 700 RSA. Which one of these stocks are the most comfortable? Do you need to bed the 700 RSA? I have heard that the AICS is great for prone shooting, and not the best for shooting off the bench. Also how much do the 700 RSA's cost? Thanks for your help!
