ABSTRACT:
A firearm-securing device providing tamper resistance features which device includes a keyway that operates a threaded rod which, in turn, controls spring-loaded cams that obstruct a tubular area including a chamber, a barrel, and a muzzle of a firearm. The cams have either fixed or articulated contact pads. Operating the keyway in clockwise rotation causes the cams to wedge against the inner chamber and barrel surfaces, locking the device in place. Counterclockwise keyway rotation unseats the cams, allowing the device to be remove from the chamber and barrel and thus allow operation of the firearm. The device includes several components designed to minimize tampering of the device itself as well as tampering of the firearm.
