The biggest changes from the Icon are out of sight. For starters the Renegade 2 does not have the flat-bottomed receiver that the Icon does. For those not familiar with the Icon, one of its accuracy-enhancing features is its bedding system, which mates a flat-topped aluminum bedding block to the flat-bottomed receiver. The theory behind the flat-on-flat design is that there is no chance for the action to roll or torque in the stock. In addition, the flat bedding block adds rigidity to the whole business, which is always a good goal as far as accuracy is concerned. Instead, the Renegade 2 has a round bottom design (round is always cheaper and easier to make) that mates to a stock that doesn't have any special bedding features.
