They are quite nice rifles but in conversation with Tony Belas a few years ago he said they stopped making them basically because they were losing money on them. So many were being returned to the factory with faults. One pump gives around 5 - 6 ft lbs while the 2 pumps will get you 10 or so but the second pump is hard going. I did an HFT course with one once ... and once was the operable word as somehow I did not want the effort again.
