The present invention provides a simple and economical means for securing most firearms and consists of a unit body base used in conjunction with a conventional bore cleaning apparatus. The unit body base is designed to precisely fit firearm chamber dimensions with the rim circumference altered from standard ammunition casing profile. Consequently dry firing operation of the firearm can occur while maintaining a secured chamber. The unit body base is threaded to receive a bore cleaning apparatus oversized to the firearm chamber diameter, this provides mechanical resistance to manual removal of the device from the action or breech of the firearm. When the device is properly seated, live ammunition can not be readily chambered, so as to protect the firearm from unauthorized or unintentional discharge.
