The BPS has a mix of a classic look with modern fit and handling. It starts with a satin finished walnut stock, a matte blued barrel with a ventilated rib, as you would expect from a Browning. Then the stock has been slightly reconfigured to offer a faster, more natural feel. The Inflex recoil pad offers excellent comfort and the new checkering surfaces offer a superior grip. The S/R selector ring on the 5th photo means "Single shot or Repeat". It will enable you to change the shell in the chamber or open the action for crossing a fence without emptying the magazine. No choke
