I would agree that the original FAS604 is superior to the newer 6004, they are a fine, well made and very accurate pistol, it's also nice being able to shoot it under its own power, no need for bottles, pumps etc. Always had a soft spot for these and for good reason too . I also have a modern sci fi looking pistol (Steyr) but can shoot the older SSP pistols just as well, the modern PCP does come into its own when shooting a full 60 shot comp though,
