An unfinished AR upper made from a 60% Beryllium alloy is being sold on GunBroker. Dr. Strange gun pointed out that Beryllium is toxic. Machining and finishing it off could cause Berylliosis, a chronic lung disease that has no cure.

Even handling it could be have unpleasant side effects. According to wikipedia:

Beryllium contact with skin that has been scraped or cut may cause rashes, ulcers, or bumps under the skin called granulomas.

Scary stuff, considering the buyer may not be aware of this.

    gyrfalcon, wikipedia still says that it is toxic. The problem is that it is unfinished.

    "In solid form and as finished parts, beryllium copper presents no particular health hazard." Wikipedia

    "Handling -- There are no special toxic hazards associated with the handling of copper beryllium alloys or with material taken orally. However cuts and abrasions should be treated by normal first aid methods and it is advised that after contact with copper-beryllium alloys the hands should be washed before food is eaten. Care should also be taken, as with other metal alloys, to remove all metal particles from the wound whilst normal hygiene standards should be observed." -- http://www.cda.org.uk/megab...
