You can still get them... sort of. The market has fallen out (aftermarket parts that is) for these guns as electros are becoming cheaper, the trilogy cockers, etc...
Heck, by the time you figure out the cost of a few aftermarket parts, you could have a whole new gun.
And since it is quiet and guns are cheap, the makers are aftermarket parts have more or less stopped producing new parts.
There are still some hold outs, and they are just the top of the line parts... But not much around, I agree.
