Air Arms S400 MPR – Poplar Stock – To fill the gun, unscrew the air reservoir and attach it to the 200-bar DIN hole of a scuba tank or hand pump. The end of the reservoir has a manometer (air pressure gauge), so you’ll always know how much air is left in the tank. The correct air pressure for the MPR is 200 bar (2,900 psi).
