If you enjoy winning field target matches, the Air Arms S400 MPR FT (multi-purpose rifle field target) can help you achieve your goals! The gun is highly adjustable to meet your individual shooting needs. The match trigger is not only adjustable for first-stage length and second-stage pull weight, but it also can be moved up or down and forward or back. Plus, the trigger pad can be adjusted! An adjustable cheekpiece moves up and down to align your eye with the rear sight, while the thick rubber buttpad is also adjustable. If you need a longer pull, unscrew the buttpad and add spacers (not included). There are no sights on the gun, so be sure to get a scope and mount! This is a breechloader and the S400 MPR FT has a 12-groove Lothar Walther barrel and poplar stock. The correct air pressure for the MPR is 200 bar (2,900 psi). The tank is not removable. You refill it while it's attached to the gun.
