Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture would contain a variety of pure gases much like the air. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colorless gas invisible to the human observer. The interaction of gas particles in the presence of electric and gravitational fields are considered negligible as indicated by the constant velocity vectors in the image. One type of commonly known gas is steam.
The gaseous state of matter is found between the liquid and plasma states, the latter of which provides the upper temperature boundary for gases. Bounding the lower end of the temperature scale lie degenerative quantum gases which are gaining increasing attention. High-density atomic gases super cooled to incredibly low temperatures are classified by their statistical behavior as either a Bose gas or a Fermi gas. For a comprehensive listing of these exotic states of matter see list of states of matter.
So over the past few years I've built around a dozen black guns with pretty good success. But a current build has me scratching my head.

Could I remove the part of the gas key that would normally slip over the gas tube (see photo) and retain the non gas related function of the gas key?
I would be removing the portion of gas key covered by the green tape.

I have question on the AK-47 gas piston. With my M14 you keep the gas piston and cylinder dry. Is it the same for AK-47 to keep it dry as well? What about the gas cylinder too?
Just using CLP to cleaning and lubing right now.
New old stock. I bought this about a decade ago. I've never put a drop of fuel in it. Gas tank is bone dry having never been filled. It's never been turned on, obviously. It's been stored covered under plastic in my garage. Cord is still coiled and zip tied as it was when new.
Mine is the...
