Za'tarc ring

The Za'tarc weapon (true name unknown) is a small weapon which was probably invented by the Goa'uld.

Functions
The device is very small and is worn around the wearer's finger, much like a ring. Thus it can be easily concealed, making it an ideal weapon for a brainwashed Za'tarc. After activation the device enlarges a bit and then can be used to fire a laser-like red energy beam which is powerful enough to blast through a persons body and has a large recoil. A secondary effect of the weapon is its self-destruct device which can be triggered by pressing a small blue button on the weapon. After a few seconds the device explodes, completely destroying the wearer.

History
The device became first known to Stargate Command during a meeting with the Tok'ra. There Major Graham pulls out such a device to kill the Supreme High Councilor Per'sus of the Tok'ra but fails and subsequently kills himself. Another such device is later used by Martouf to kill the President of the United States but he is also stopped.

Another such weapon is used by Osiris about three years later in her fight against SG-1.

The last known user of the device is a female bounty hunter who attacks Daniel Jackson after a bounty had been placed on the team by Netan, leader of the Lucian Alliance.
