  • Patent number: 6543171
    Abstract: A firearm safety lock comprises a chamber insert and a muzzle insert secured together through the barrel of a firearm by an swiveling adjustable-length cable connection. The chamber insert is sized to fit within the breech of a firearm, and to prevent the loading of ammunition therein. The chamber insert receives a first end of a flexible cable, which is secured to the chamber insert by a swivel connection. The flexible cable extends the length of the firearm barrel, and is fitted, at the opposite end, to a lock receiving rod. The lock receiving rod includes at least one circumferential groove, and passes through an axial bore in the muzzle insert. The flexible cable length is adjusted such that a portion of the lock receiving rod is retained within the barrel, and a portion extends external thereto.
