Dry Firing Device for Anschutz Super Air 2002 SSP

[lognom]

Hi,
In a recent post, one of the other forum members pointed out that the owner's manual of the Anschutz Super Air 2002 single stroke pneumatic rifle alludes to a dry firing accessory. Has anyone every seen this? I'd like to purchase one, but my internet search has drawn a blank. My rifle is left handed, so I hope this won't make any difference.

Regards,
Lloyd
