Xisico XS-B9-1 is a tactical airgun that assembles in seconds by simply attaching the barrel group to the receiver with a hand turned knurled nut...and it shoots pellets from a ten round magazine or can be fired in single shot mode. The XS-B9-1 is equipped with a 4X32 scope which is attached to the barrel so it retains its superb preset accuracy. To use the XS-B9-1 as a repeater, just cock the piston spring powered air gun with the side lever, drop in a loaded clip of pellets, and fire up ten rounds simply by cocking the rifle and pulling the trigger.
