A cylindrical insert (42) having a recess (50) in one end and a notch (46) disposed between either end of the cylindrical insert (42). The cylindrical insert is placed within a bolt carrier (122) of a rifle or firearm. The recess (50) is positioned to receiving the firing pin (132), preventing the cylindrical insert (42) from contacting it. The notch (46) is sized and positioned to receive the hammer (130), preventing it from impacting the firing pin (132) when the trigger (126) is pulled releasing the hammer (130). The insert (46), being placed within the bolt carrier (122), is not readily visible and effectively disables the rifle from being fired. This prevents the possibility of any accidental discharge or unauthorized use. A locking device may be attached to the insert (42) preventing its unauthorized removal. The present invention is applicable to many different rifles or firearms and may also be used to safely dry-fire a firearm without damaging the firing pin, and requiring only limited movement of the bolt carrier to reset the hammer for dry-firing.
