Are these guns still selling quite well?

You cannot expect the quality of the originals for the price Chiappas is charging. They're only about $400 in the US.

But then I remember a time when the original 604 came in for its fair share of criticism for leaks and perished seals. I think some retailers stopped selling it because of these problems.

Maybe for someone who just likes to shoot at home the 6004 would be a fnice alternative to the huge top heavy HW75.

What bothers me is the low velocity the gun appears to produce. I read somehwhere that a gun producing less than 390 fps will not make clean holes in a Bisley paper target.

If any owners would care to comment on this I'd appreciate it. Does it seem sturdy enough to last a few years? Would a HW40 for home use be a more sensible option, or is the 6004 worth the extra money?
