IMHO the s400 MPR FT is one of the most under rated rifles out there. Easy to work on and the 2 I've owned were super accurate. The rifle (in good condition) would be around the £550 to £600 with another £50 the pump. Check for any rust spots on the barrel or cylinder as the AA bluing is prone to this but even if there are i wouldn't worry too much as long as the price reflected it. Barrel and cylinder are easy to source and replace and if marked can be covered with dipping or carbon look tape. If you need any more info then please feel to PM me and i'll help in any way i can.
