Transferable machine guns made or registered before May-19th 1986 are worth far more than their original, pre-1986 value. And items like registered “auto-sears,” “lightning-links,” trigger-packs, trunnions, and other “combination of parts” registered as machineguns before the aforementioned date are often worth nearly as much as a full registered machine gun. For instance, as of September 2008, a transferable M16 rifle costs approximately $11,000 to $18,000, while a transferable "lightning-link" for the AR-15 can sell for $8,000 to $10,000. New manufacture M-16s sell to law enforcement and the military for around $600 to $1000.
