gas tube
A gas-filled tube, also known as a discharge tube, is an arrangement of electrodes in a gas within an insulating, temperature-resistant envelope. Gas-filled tubes exploit phenomena related to electric discharge in gases, and operate by ionizing the gas with an applied voltage sufficient to cause electrical conduction by the underlying phenomena of the Townsend discharge. A gas-discharge lamp is an electric light using a gas-filled tube; these include fluorescent lamps, metal-halide lamps, sodium-vapor lamps, and neon lights. Specialized gas-filled tubes such as krytrons, thyratrons, and ignitrons are used as switching devices in electric devices.
The voltage required to initiate and sustain discharge is dependent on the pressure and composition of the fill gas and geometry of the tube. Although the envelope is typically glass, power tubes often use ceramics, and military tubes often use glass-lined metal. Both hot cathode and cold cathode type devices are encountered.

PS don't tell anyone I have an AR15 or two, remember comrades rifle is fine.

I ordered a gas tube and it says the roll pin is included but there wasn't in the package. Can I go to the hardware store and buy an appropriate sized buy one? I have a few spare extractor roll pins but they are too large. I have fewer lower parts kits does anyone if roll for the lower kit will...

Anyone got one lying around that they don't need? Checking local before I break down and buy one online. I waited in line at Keith's today to get one and they were asking $21. No thanks. I could trade for a box of 9mm ammo or cash.
