Why drop in autosears sold for $40k–$52k — the tiny device worth more than many guns
This entry details the function and legal classification of a Drop-In Auto Sear (DIAS), a device that converts an AR-15 receiver to full-automatic fire. It highlights the extreme rarity and value of registered, transferable DIAS units, with only two known to exist in the US before 1986, commanding prices of $40,000-$52,000. Unlike registered receiver guns, a DIAS is considered a self-contained legal machine gun.
