I've been thinking about buying a remington 700 sps tactical in 308 and then upgrading the stock and making it use AI magazines and putting a larue 20moa scope mount on it. But got an offer to buy a remington 700 police 308 and Leupold VXIII 6.5-20x Long Range Target scope for $1500 should I get this setup? I like the sps's 20inch barrel and would probably have the barrel cut on the 700p
